• How To Fuel Before, During, And After An Ultra Marathon

    ultra marathon running race how to fuel nutrition hydration

    Fuelling for an ultra marathon is possibly one of the most difficult areas to get right and one of the main reasons runners drop during distance racing. As runners, we tend to focus on the obvious: our physical training and endless kit choices. However, fuelling and mindset are two really important areas which can be neglected.

    This year I am competing in the Centurion Grand Slam: a series of four 100-mile foot races in May, July, August and October. I have completed this distance twice previously but doing all four within a year has been a very different experience and a massive learning curve. Time of year, trail conditions, course and temperatures all play a big part in the fuelling strategy.

    Pre-Race Fuelling

    Pre-race fuelling is the easy part. Contrary to popular opinion, 'carb-loading' shouldn't be eating everything in sight the night before the race. Instead, you should gradually increase your carbohydrate intake in the week leading up to the race in order to get your body used to storing more fuel.

    There is a limit to how much fuel can be stored in the muscles. Most sources estimate 400gm or 1600 calories, but each individual is different. Personally, my diet does not change too much the week before a race. I tend to eat little and often with 6 smaller portion meals which are easier to digest than opting for 3 larger meals which will just leave me feeling bloated and uncomfortable. I also ensure I am hydrating well.

    I tend to increase my carb intake and reduce my consumption of fruit and vegetables; the less fibre the better as this will prevent gastric issues while you are running. Normally I love spice in my food, but on endurance events your digestion system will be taking a back seat as all energy focuses through the big movement muscles, therefore it is best to stick to plain and bland foods to avoid stomach upset.

    I am very much a creature of habit on the “final dinner” which is always pasta with fresh tomatoes, garlic, basil and olive oil. I eat dinner 2 hours earlier than normal, followed by a sandwich an hour before bed. You want to allow time for your dinner to digest before bed, so when you have to get up for an early start, your body is ready to complete the digestion process – meaning no last minute toilet queues!

    Key points:

    • Don't eat everything in sight the night before the race. Carb load for an entire week before the race by eating little and often and gradually increasing your carb intake.
    • Reduce or eliminate entirely your intake of fruit and vegetables. Less fibre will prevent an upset stomach or gastric issues/emergency toilet stops.
    • Avoid spicy foods, stick with plain and bland foods.

    Race Day Fuelling

    If you can eat breakfast, keep it light. If nerves get the better of you and you feel like you can't eat: don’t worry.

    For marathon distance, gels work well for most people and are a convenient choice, however on the longer distance you really need to be able to eat “real” food. Checkpoints are usually stocked with a variety of sweet and savoury foods and on longer distances, the later checkpoints will even provide hot food and drinks.

    It is worth checking your race information, which usually lists the type of foods and drinks you can expect. If you have specific dietary requirements, you may need to be more self-sufficient – I am vegan so this applies to me. It is also worth carrying emergency supplies on your person.

    Start fuelling early and take plastic bags with you so that you can take away foods from the checkpoints to eat while you continue to run. You may need to slow your pace to allow your body to digest the food properly. 

    Some ultra marathons and most races beyond 100km will allow access to drop bags and crew at designated points so ensure you pack some food into your drop bag (in addition to extra kit). It is difficult to decide before the race what you will feel like eating, but get some of your favourites in there – it’s always nice to have a special treat to look forward to.

    Nausea is one of the most common things that prevents runners from finishing ultra marathons. If you are feeling or being sick, you are losing energy and hydration – lack of both will cause the body to dip mentally and physically. As difficult as it may be, you need to keep eating and hydrating. If you feel nauseous, try slowly chewing crystalised ginger as this can settle the stomach. Also try chewing gum.

    Hot Weather

    Weather conditions also affect your fuelling strategy. Extreme heat can make it difficult to eat and you might have a tendency to drink in excess which will cause a sloshing effect on an empty stomach. It’s always a good idea to carry some money so that you can buy a cold drink or ice cream, or ask your crew to have some ice and cold drinks available.

    Night Races

    If your race takes you through the night, the body will find it difficult to digest as it’s simply not used to eating through the night. Keep eating little and often and if there are hot drinks available from checkpoints and crew take advantage of this; it will also keep you warm.

    Sodium Replenishment

    Replenishing sodium is something you should have practised in your training. As you sweat, you will lose body salts and minerals so over long endurance events it is vital to replace as you go along, otherwise you may suffer nausea and muscle cramp. There are lots of products on the market in tablet and liquid form – get to know your body and practise in training, and carry additional in your hydration vest on race day. Also bear in mind seasonal factors; it’s easy to tell you are sweating in the height of summer, but you will also be working up a sweat in the middle of winter.

    Post Race Fuelling

    Race completed: permission to eat the world granted! Do not be surprised if in the first 24 hours you have no appetite – your digestion system has to re-boot and this generally requires sleep. I find that after a 100-mile ultra marathon I sleep for a few hours, wake up hungry, eat a little, then sleep again – this is the first 24 hour routine.

    Once your appetite returns, make sure you fuel little and often. It’s natural to feel fatigued between meals as your body runs out of food. The best advice on post ultra-fuelling is to listen to your body. Ideally, you require all food groups, but you may crave protein as the body will want to repair muscles. I tend to want protein and masses of fruit and vegetables as my body craves the nutrients from the vegetables. Dependant on the distance of your ultra, recovery will take from one week to usually six weeks for a 100-miler. A spa treat to relax both body and mind the week after a tough race is a great idea. Look after your body – it has served you well!

  • Runner's Winter Strength Workout

    Strength workout for runners winter indoors

    When it comes to running, there's more to it than just pounding the pavement. In order to avoid injury and stay strong, you need to cross train to keep your muscles and joints healthy. Follow our runner's winter workout to give you the base you need to succeed.

    Indoor Winter Workout For Runners

    Warm Up

    Leg Swings

    Hold onto a wall or bar for support, and swing one leg in front and behind you 10 times. Repeat on the other leg. Make sure you feel the stretch in the hamstring as the leg comes forward, and the stretch in the hip as it goes behind you.

    Lateral Leg Swings

    This is the same thing, but now you swing the leg from side to side in front of you. Feel the stretch in the inner thigh (adductor) as the leg swings out to the side.

    Hip Openers

    For this warm up, you imagine you are stepping over invisible hurdles. Lift up your left leg and step it sideways over an invisible hurdle, making sure as the right leg comes over it steps over too. Do 3-4 steps one way and repeat going back the other.

    Main Set

    Banded Back Squats

    Back squats are a great exercise for runners as they target all of the muscle groups in the legs. By using a resistance band round your knees, you will train your hips to stay open and encourage perfect form. This will also help to strengthen your IT band which is a common cause of injury for runners.

    Place the resistance band just above your knees and keep your knees pushing outwards for the duration of the lift. Place a bar on your back and drop into a squat. Make sure your hips drop below your knees and then use your glutes to squeeze you back up. Complete 3 sets of 10 on a fairly light weight.

    Banded Front Squats

    Front squats also work all of the muscles in the legs, but they also encourage you to keep your chest up because the bar is on your front. Front squats will work your glutes harder as you can't cheat!

    Place the resistance band just above your knees again but this time place the bar on your front, supporting it with your hands. Keep your elbows high. Keep your chest proud and drop into a squat. Make sure you really squeeze your glutes so that you can shoot back up without leaning forwards and dropping the bar. Complete 3 sets of 10 on a light weight.


    Deadlifts are another important exercise for runners as they will strengthen your back and core so that you can stay strong throughout the race and not suffer from any aches as the miles rack up.

    With the bar on the floor, place your feet under the bar so that it touches your shins and bend your knees so that you can grab the bar. Keep your bum down and your chest high, squeeze your shoulder blades together and pick the bar up off the floor. Lock out at the top by pushing your hips slightly forward and then bend back down to place the bar back on the floor. Do 3 sets of 10 on a fairly heavy weight. Make sure you keep your back dead straight throughout the lift and squeeze your core tight to protect your spine. 

    KB Single Leg Deadlifts

    This is a fantastic exercise, especially if you suffer with pain in your feet and ankles when you run. It will correct any strength imbalances between your legs and help with your balance as well as leg strength.

    Start with the right side: Find your balance on your right leg and hold the kettlebell in your right hand. Slow lean forward so that the kettlebell lowers to the floor while simultaneously lifting your left leg behind you. Squeeze your glutes so that your left leg lifts nice and high and see if you can lean all the way forward so that the kettlebell touches the floor. Slowly pivot back to centre. Repeat 10 times then switch to the other side.

    KB Side Leans

    Time to target the abs. Hold the kettlebell in your right hand and keep it by your side. Lean to the right, moving only your waist. Slide the kettlebell down your right leg and then squeeze your abs to come back up. Repeat 10 times then swap to the left side.

  • How To Fuel Long Runs

    how to fuel long runs

    If you're starting to ramp up your running and are training for a half marathon, marathon, or even ultra marathon, it's important to know that your nutrition strategy is key to success. We give you all the information you need on how to fuel for long runs.

    What is the best thing to eat before a long run?

    When running long distance, what you eat before your run is just as important as how you fuel throughout. When training for an event on a specific date, it's important to steadily increase your carbohydrate intake in the week leading up to the event so that you can get your body used to storing more energy. But beware, don't fall into the trap of 'carb loading' the night before the race by eating a load of pasta and then going to bed! You need to build up gradually over several days, rather than just eating more than usual the day before.

    For your regular training runs, there are a few different things that will fuel you well before you head out. Eating a good breakfast will set you up well whether your run is morning, afternoon, or evening. Opt for something carb-rich but also high in protein, such as eggs on toast or oatmeal with fruit. This should be eaten around 2 hours before your run so that it has time to digest and won't sit heavy in your stomach. Around 30-60 minutes before you run, eat something with simple sugars such as a banana to give you one last boost.

    What to eat 2 hours before a run

    • Oatmeal with fruit and nuts/seeds
    • Eggs on toast
    • Protein pancakes
    • Ham and cheese sandwich
    • Peanut butter on toast
    • Chicken, rice, vegetables

    What to eat 30-60 minutes before a run

    • Banana
    • Protein shake
    • Some crackers
    • Raisins
    • Apple sauce

    Mid run fuel

    When it comes to mid run fuel for long runs, different things will work for different people. The ultimate debate is whether to eat real food or not. By this, we mean the difference between a peanut butter sandwich and an energy gel. Some people are happy to fuel solely with sugary gels and drinks, but this doesn't work so well for others. 

    In order to find out what works for you, it's best to go with the trial and error method in your training runs. Remember, nothing new on race day! Try different foods and gels and see which make you feel the best. It could be that a combination of both works for you. 

    Foods which are great for mid run fuel:

    • Protein balls
    • Flapjack/Granola
    • Peanut butter sandwiches
    • Pretzels (good for sodium but can be very dry, especially if you’re dehydrated)
    • Pickles and pickle juice (great for cramps)
    • Dried or fresh fruit
    • Sugar cubes
    • Energy gels
    • Sports/electrolyte drink

    You also need to remember that whatever you decide to fuel with, you need to be able to comfortably hold or carry with you while you run. Some people don't mind holding a bottle in their hand while they run, but others may find that to be uncomfortable. Work out what you like best and practice running with a hydration bag, bottle, and snacks in various pockets. 

    It's also important to remember that being as self-sufficient as possible is best for racing as you never know what kind of fuel and hydration will be available to you on the day. There's nothing worse than gasping for a drink and running along waiting for the next water station only for it never to arrive.

    Running fuel for sensitive stomachs

    If you have a sensitive stomach or you find that certain foods or energy gels give you gastric problems during your run, you need to be extra careful. Here are some top tips for finding running fuel for sensitive stomachs:

    1. Avoid caffeine
    2. Stick with bland carbs like toast, bagels, and oatmeal
    3. Avoid spicy foods
    4. Avoid eating too much fibre 
    5. Seek out energy/protein bars with minimal ingredients

    Homemade running fuel

    If you don't like the idea of eating something full of chemicals or constantly buying expensive energy bars and gels, you can make your own homemade running fuel. There are lots of options, from homemade trail mix to even make your own energy gels! Read more in our article below.

  • How To Properly Warm Up (And Avoid Injury)

    warm up exercise workout stretch

    We all know we should do it, but many of us don't know how to warm up properly before training or running. We give you a run-down of how to warm up properly to avoid injury.

    What happens to your body when you warm up?

    Before you exercise, your muscles will be somewhat cold (dependant on outside temperature) and usually quite stiff (especially if you rarely stretch). Additionally, your heart rate will be at resting rate which is much lower than working rate and your breathing rate will be low. When you exercise, your muscles need to be warm and limber and your heart rate and breathing rate will increase. 

    When you warm up, you are easing your body into a working state. You will be warming up your muscles, increasing blood circulation, increasing heart rate, and increasing your body temperature. All of this will improve circulation to your muscles so that they can perform better while you are exercising and will reduce the likelihood of injury. Not only this, a warm up can prepare you mentally for the workout or race ahead and help you get into the right frame of mind.

    How long do you need to warm up?

    How long you need to warm up depends on what type of race, game, or workout you are about to do. If you are going to do a short run such as a 5k, you will only need to warm up for a few minutes. If you are going to do a big workout at the gym, lifting weights or doing HIIT, you may need to warm up for a little longer, up to 5 minutes. 

    If you are about to play a team sports game such as football or rugby, you will require a longer warm up, and this will usually involve drills as well as team work to prepare you for the game or match. A big event like a triathlon or Ironman will also require a much longer warm up and you may spend up to 20 minutes warming up in anticipation of an event like this. 

    lunge warm up workout stretch exercise

    What happens if you don't warm up?

    Missing or skipping a warm up can be quite costly and you could get injured. Especially if you are going to be lifting heavy weights in your workout, you could pull a muscle or end up with a tear. Not only this, by not preparing your body for a workout, it won't be ready to cope with the added stress and therefore you may not perform as well. 

    Warming up is not the only important thing: you must cool down properly after exercise, too. You will often see people whizz off the end of a treadmill after a tough workout and just walk straight out of the gym. This is a bad idea: when you exercise, your heart is pumping extra hard and pushing more blood around your body. If you don't cool down properly, you will end up with 'blood pooling' which, while not as bad as it sounds, can lead to cramping and injury. 

    What are good warm up exercises?

    It's never a good idea to do static stretches before a workout as this could tear your muscles. Additionally, it's not recommended to do static stretches after a workout either as your muscles have just torn and stretched during the workout, so you don't want to exacerbate this effect by stretching them further.

    Instead, it's best to do dynamic stretches and drills as a warm up. The best warm up exercises include things like windmills, where you swing your arms round in circles, leg swings, high knees, fast feet, and kick backs.

  • The Worst Mistakes To Make During A Race

    running mistakes race marathon professional athlete Sundried

    From forgetting something to going the wrong way, we've all been there. Sundried asked our ambassadors "what is the dumbest thing you've ever done at a race?" and these were their answers! Have you ever made any of these racing mistakes?

    Helene Wright - Triathlete

    I was once on the bike leg of a duathlon and knew I was second lady so was chasing down the leader. I saw a cyclist in the distance so pushed on to catch them. As I got closer I soon came to realise they weren't wearing a number so they weren't even in my race... But worse still I'd followed them off course and down to the bottom of a hill!  Fortunately, after getting back into the race, I hadn't lost a place but didn't track down the leader in time to win first place.

    John Wood - Team GB Triathlete and Coach

    A client of mine raced Cardiff Triathlon as part of training and forgot his wetsuit.

    Dominic Garnham - Triathlete

    I trained hard throughout all of last winter for a race early this year. I felt very confident and very excited for the race and I was in the best shape I've ever been. I turned up to sign in at registration on the day only to find I had forgotten to actually enter the race! 

    Nick Lower - Celebrity Trainer

    I fractured my ankle 7 miles into ‘Man v Mountain’ (a 20 mile race up and down Mount Snowdon). I stupidly just strapped it up and completed it!

    Alice Tourell North - Team GB Triathlete

    At a recent race I forgot to put my race belt on! I had the best swim I’ve had this season, flew into T1, got to my bike... and then had to stand there for over 3 minutes whilst the race officials tried to find my husband who had the race belt in my bag. Total nightmare!

    Steve Sayer - Triathlete and Coach

    My swim hat pinged off and I lost my goggles at Ironman 70.3 Wimbleball, but I had the fastest swim stroke ever!

    Martin Owen - Team GB Triathlete

    I had an issue until recently of not being able to pedal and drink at the same time. I used to have to coast very slowly to drink. In a standard distance Duathlon, my bottle wouldn’t go back into the holder and it dropped out on the first lap. 35 more miles on 1 gel and no water...not nice!

    Anne Iarchy - Personal Trainer

    I hadn't ridden my bike for a couple of years due to injury. I had entered a triathlon last year, hoping I would have the time to get back on beforehand. Unfortunately that didn't happen. As I got onto the bike leg, I had totally forgotten how to change the gears on the bike. I managed to take them up, but not down. So when pedalling into the wind, it was really hard work. Thankfully I managed to figure something out on the 3rd lap!

    Simon Ward - Team GB Duathlete

    I turned up to the European Duathlon Championships with a broken neck. I ran 10k, biked 60k, and then ran the final 10k in the most pain I have ever experienced!
