Triathlon is a complex sport and takes a lot of research, effort, and knowledge for those just getting started. We talk to professional triathletes and GB Age-Groupers about what they wish they'd known before they started out. 

Paul Suett - Team GB Age Group Triathlete

I wish I had known how to properly pace a race rather than going out as fast as I can for as long as I can. I seem to have got the grips of it now though.... well, most of the time!

Alice Tourell North - Team GB Age Group Triathlete

I wish I’d known how completely obsessed I would become with it! I did two races as a total beginner then went to my first Age Group World Championships in Edmonton, Canada and was instantly hooked. It’s the most competitive hobby I’ve ever had but I wouldn’t change a thing - my husband may disagree with this though as all his holidays, including our honeymoon, now include a triathlon!

Dominic Garnham - Team GB Age Group Triathlete

1. Quality training over quantity. Train smarter, not more.

2. Build up training slowly to prevent injury.

3. Just have fun! if you're not a professional triathlete, you don’t get paid to do this.

Megan Powell - Team GB Age Group Triathlete

I wish I'd realised how different the run at the end of a triathlon feels!

Melissa Hinojosa - Mexican Triathlete

1. How addictive it is

2. How expensive it can be to gear up (especially bike-wise)

3. When travelling to compete, your luggage will multiply and flying with your bike can be challenging/uncomfortable.

Ian Dodds - Amateur Triathlete

That silly 'kicking my bum with my heels' thing at the start of the run is actually super helpful and worth looking a bit ridiculous.

Ali Trauttmansdorff - Team GB Age Group Triathlete

That lots of people start to think you are either nuts or superhuman or both, but really you are just someone with resilience and motivation who is willing to feel challenged and push the limits for a few hours.

Sophie Kennedy - Team GB Age Group Triathlete

1. I wish I knew how much I would love races! I certainly would have enjoyed doing them earlier in life, but didn't enter until my boyfriend suggested I should.

2. Don't be put off by the price, have a look around at different events and locations as prices can differ quite a lot. Also they are worth every penny anyway!

3. In terms of the triathlon itself: My first one I'd never swum in open water before so I zig-zagged my way round the lake. It's definitely worth looking into spotting techniques and practising beforehand. Your cadence on the bike and the run can massively help with the weird legs feeling from bike to run.

What gear do I need for a triathlon?

Before you begin your training, make sure you have all the gear you need to train and race. Triathlon is a complex sport with lots of moving parts, so you'll need a few different pieces of kit. Read our beginner's kit guide for first-time triathletes which outlines all of the gear you will need from a trisuit to running trainers and everything in between.

What do I need to pack for a triathlon?

Wetsuit

Official British Triathlon events have a steadfast rule that if the water temperature is below 15 degrees Celsius you are obliged to wear a wetsuit for the swim. If the triathlon you have entered takes place in an indoor pool then you will not be required to wear one, but most open water swims in the UK will require one.

Wetsuits keep you warm and also aid buoyancy, so for new triathletes, they’re an important bit of kit. 

For your first triathlon, it can be expensive to buy a wetsuit that you may only wear once, but you can hire a wetsuit just for the one event, and at some there will be the option to hire one on the day and even have it fitted there and then.

Tri suit

A triathlon suit is a key piece of triathlon gear. Specifically designed for the sport, the tri suit is made from thin, breathable material with a second-skin feel to prevent chafing and to stay comfortable throughout all three disciplines. By wearing a tri suit you won't need to get changed, meaning your transition times will be vastly improved and it will save a lot of hassle! 

Tri suits are made with a built-in chamois pad to protect you on the ride, but this will be somewhat smaller than on cycling shorts so that it does not inhibit you on the run. You can wear your tri suit under the wetsuit for the swim.

Goggles

Goggles will be a must for the swim, especially in open water. Higher spec goggles will not only protect your eyes from the water but will also prevent glare and UV damage from the sun.

Swim Cap

Often, race organisers will provide these, as your swim cap may have your number on it. It is often advised to still bring your own to wear underneath. Wearing a swim cap will stop your hair getting too wet during the swim which would then irritate you during the ride and run. It also keeps your hair out of your face while you are racing! The swim hat can be ditched as soon as the swim is over.

Bike

Depending on your level of experience and your intentions for future races, your bike can vary a lot. If you are new to triathlon and just plan to compete casually at a few sprint distance events, you will be able to race with a normal road bike. However, if you plan on doing a lot of longer triathlons - and even Ironman events - you will want to invest in a higher spec bikes. TT bikes come with different handles that you can lean on to improve speed and aerodynamics, and some will have special wheels as well. Choose your bike wisely and keep it in line with your goals.

Helmet

You will not be allowed to race in any British Triathlon event without a bike helmet. Again, your level of investment depends on your level of commitment to the sport. Some helmets at the higher end of the range will be more aerodynamic and some proper racing helmets can set you back up to £500.

Trainers

Triathlon-specific trainers have bike clips and quick fastening laces, but they’re not essential for a beginner.

Transition Towel

Having a brightly coloured or easily noticeable towel will help you find your station in transition more quickly after the swim. Most triathletes stand on their towel whilst they quickly transition to the bike.

Water

Water should be handed out by marshalls throughout the race course, but it’s always best to have your own in case you need extra. You can keep a bottle at the transition to top yourself up before the next leg of the race.

Triathlon season has begun and it's the most exciting time of year for multi-sport athletes. All those hours spent in the pain cave over winter have paid off and now it's time to reap the rewards. But what if it's your first triathlon? You're bound to have a lot of questions. Follow these 5 tips to not only survive but thrive in your first triathlon.

1. Don't underestimate an open water swim

If you've done all of your swim training in the local pool but are taking part in an open water swim event, there may be an element of surprise waiting for you. An open water swim is very different from a pool swim in lots of different ways. Not only this, it depends on the type of open water, as events range from lakes to canals to the sea and even oceans, all of which come with their own challenges. 

When choosing your first triathlon, it might be an idea to choose a pool-based swim as this will ease you into the sport and is less likely to scare you off! Especially if you are not such a confident swimmer, swimming in open water can be very tough, especially if it's tidal. Practice in a lake or the sea before the race so that you have an idea of what to expect.

2. Wear the right kit

A triathlon is very different from a running race as there is a fair bit of specialist kit you will need. Make sure you have a good quality trisuit that is comfortable and has the right support for you. You want a triathlon suit that has a chamois pad to keep you comfortable on the bike but one that isn't so big and bulky it'll get in the way on the run.

There are also other items of triathlon clothing that you may wish to get such as cycle socks, a race number belt, and even race number temporary tattoos. These are all triathlon-specific items that you probably won't have otherwise, so do your research first and make sure you have all the kit you need before the big day.

3. Don't neglect brick training sessions

If you have never tried running after cycling, you need to practice! Running off the bike is a totally different experience to running on its own and you might be taken by surprise at how your legs feel. If you haven't practised, you are more likely to get injured and it would be a shame to ruin your day.

Brick workouts are training sessions where you practice doing two or even three of the triathlon disciplines back-to-back. This is usually running after cycling as this can be one of the toughest aspects of a triathlon. Getting your legs used to doing different types of movement and being under different types of strain is very important and will prepare you well for your big day.

4. Recce the course first

If you have been training on flat ground the whole time and there is a huge hill on your race course, you are likely to suffer! Make sure you check the course before you even sign up so that there are no nasty surprises. Things you want to consider are whether the bike leg is done on closed roads or if there is going to be the hazard of traffic, whether there are any notable ascents and descents, and whether the entire race is done on road and tarmac or if any of the run or bike are off-road.

Being fully prepared for the race will be great for you mentally and will mean there is less to worry and stress about on the day. It will also mean you can train appropriately and wear the right gear!

5. Remember to have fun!

This is perhaps the most important point. It's always important to remember why you signed up in the first place and to not take it too seriously. Unless you are a professional athlete and rely on prize money and sponsorships, it doesn't matter if something goes wrong. Make sure you enjoy yourself! 

Choosing a triathlon can be tough if it's your first time. Open water or pool swim? Sprint or standard distance? There are lots of things to consider. Follow our step-by-step guide to get you to the starting line of your first event.

1. Choose a distance

There are levels for everyone of every ability in triathlon. From super sprint to full Iron distance, the distance you choose can make a big difference to your success. The distance you choose will depend largely on your current level of fitness and also whether you prefer short, fast events or longer endurance events. Going for a full Iron distance triathlon for your first ever event is probably not advisable as there are serious risks involved if you do not execute it properly.

Triathlon Distances

2. Choose a location

For your first ever triathlon, you'll probably want to stay quite close to home. There's nothing worse than being exhausted and sweaty and having to then drive for hours to get home. You'll also want to make sure the location you choose has the right hills for your level. Some events are a lot tougher than others simply because of the gradients you face, so for your first event, it may be an idea to choose a location by the coast as they are less likely to have a lot of tough hills involved.

With that said, some triathlons offer incredible locations for their races with views and scenery that you would not otherwise be able to enjoy. There is a Castle triathlon series which sees triathletes race around famous castles in the UK, while the London Triathlon allows you to enjoy the landmarks of London while you race. Some routes use disused railways and some use private grounds, so check out some of the more interesting routes to make the most of your experience. 

3. Indoor or outdoor?

An indoor triathlon can be a great way to ease yourself into your first triathlon as it removes the element of the open water swim, which can often be the most daunting discipline for newcomers. This allows you to practice performing the three sports and perfecting your transition before you tackle a sea swim, which comes with the worry of battling the tide, getting into and out of a wetsuit, and being hit by other swimmers.

4. Choose your price

Triathlon can be an expensive pursuit, and some events cost a lot more than others. Decide on your budget and then choose a race accordingly. Entry prices can range anywhere from around £30 to over £100.

5. Get your entry in early!

Races tend to sell out very quickly, especially the popular ones, so make sure once you have decided which event you're going to do that you get your entry in quickly to secure your place.
