Introduction to Strategic Pacing
Stepping into the world of ultramarathon running is a monumental challenge that demands more than just grit; it requires a sophisticated approach to energy management. As an experienced coach, I have seen countless runners collapse in the final stages of a race simply because they ignored the most powerful tool in their arsenal: the Run-Walk-Run method. This technique is not a sign of weakness, but a professional strategy used by elite trail runners to preserve muscle fibres and maintain a consistent pace over gruelling distances.
When you transition from road marathons to the trails, the terrain changes the game entirely. You are dealing with steep gradients, technical footing, and unpredictable weather. By integrating walking intervals early, you allow your heart rate to stabilise and your legs to recover before the inevitable fatigue sets in. It is about playing the long game, ensuring you have enough fuel in the tank to cross the finish line with a smile rather than a grimace.
The Biomechanics of Walking
Running is a high-impact endeavour that creates significant micro-trauma in your muscles. Conversely, power-walking engages a different set of muscle groups and allows for a moment of recovery. When you walk, you shift the load from your calves and quads to your glutes and hips, providing a vital break for your aerobic system. This rhythmic oscillation between running and walking is the secret to sustained performance.
To execute this effectively, you must prioritise your gear. A high-quality hydration vest is non-negotiable for trail ultras. It keeps your nutrition and water accessible, allowing you to refuel during those walking breaks. When you choose your kit, look for stability and breathability, as these will ensure your vest remains comfortable even after ten hours on the move.
Will It Make me Faster
Many runners fear that walking will inevitably slow them down. However, the data tells a different story. In an ultramarathon, the goal is not to maintain a sprint, but to minimise the time spent stationary or struggling. By walking the steep inclines and the technical sections, you avoid the 'blow-up' phase where your pace drops to a crawl. You are effectively keeping your average pace higher by being disciplined.
Think of it as a tactical advantage. If you run until you are completely exhausted, your recovery time increases exponentially. By incorporating walk breaks, you maintain a steady state of effort. This ensures that when the terrain levels out, you have the physical capability to return to a strong running gait. You are essentially 'banking' energy for the final quarter of the race, which is where most ultramarathons are won or lost.

How long before I see improvements
Consistency is the cornerstone of progress. You should start integrating the Run-Walk-Run method into your long weekend runs immediately. Within four to six weeks of dedicated practice, you will notice that your heart rate remains lower for longer periods and your muscle soreness post-run is significantly reduced. This adaptation allows you to increase your weekly mileage safely, which is the most effective way to build endurance.
It is important to remember that this is a skill. You must practise your walk-to-run transitions so they become second nature. Do not wait until the race day to test your intervals. Use your training runs to find the rhythm that works best for your specific physiology. Over time, you will find that you can sustain higher intensity efforts for longer, proving that intelligent pacing is superior to sheer willpower.
10 alternative training techniques
- Hill Repetitions: This involves finding a steep incline and running up it with maximum effort before walking back down to recover. It builds explosive power in your glutes and quads, which is essential for navigating technical trails. By training your body to handle the climb, you improve your overall efficiency and aerobic capacity.
- Fartlek Training: A Swedish term meaning 'speed play', this technique involves varying your pace throughout a run. You might sprint to a tree, then jog to a fence, then walk for a minute. This unstructured approach helps you adapt to changing terrain and keeps your training sessions engaging and highly dynamic.
- Tempo Running: This requires running at a 'comfortably hard' pace for an extended period. It teaches your body to clear lactate more efficiently, which is critical for maintaining performance in the middle stages of an ultra. Consistent tempo work will shift your anaerobic threshold, allowing you to run faster for longer.
- Long Slow Distance (LSD): The foundation of all endurance training, LSD runs are performed at a conversational pace. The primary goal is to build capillary density and strengthen your tendons and ligaments. These runs should make up the bulk of your training volume, providing the aerobic base required for ultra-distances.
- Negative Splits: This involves running the second half of your workout faster than the first. It is a mental and physical challenge that trains you to conserve energy early on and finish strong. Mastering negative splits is an excellent way to prevent starting too fast and burning out prematurely.
- Strength and Conditioning: Incorporating bodyweight exercises like lunges, squats, and planks is vital for injury prevention. A strong core and stable hips allow you to maintain proper running form even when fatigue sets in. Prioritising two sessions a week will significantly improve your running economy and overall longevity on the trails.
- Plyometrics: These are explosive movements such as box jumps or bounding that improve your reactive strength. By increasing your power output, you become a more efficient runner, capable of handling uneven ground with greater ease. Plyometric training should be done carefully to avoid injury, starting with low-impact variations.
- Trail Technicality Practice: Spend time on paths filled with roots, rocks, and mud to improve your proprioception and balance. This training helps you navigate tricky terrain without wasting energy on unnecessary foot strikes. Increased technical confidence allows you to maintain momentum where other runners might be forced to stop or slow down.
- Heart Rate Zone Training: By using a monitor to stay within specific zones, you ensure you are training the correct energy systems. This prevents 'junk miles' where you run too hard for recovery or too slow for aerobic development. It is the most scientific way to structure your effort and monitor your physiological progress.
- Cross-Training: Engaging in low-impact activities like cycling or swimming can boost your cardiovascular fitness without the repetitive stress of running. This is an excellent way to maintain your aerobic base during periods of recovery or when managing minor niggles. It provides a comprehensive approach to fitness that supports your primary running goals.
