As a continuation of the previous article in which we described how to start trail running, this month we wanted to focus on an post about how to start preparing for your first short trail races.  

This post offers strength and resistance workouts, an 8-week training plan for a 15km trail run, and a calendar of races in Spain, France and Switzerland. It also provides practical advice for beginners and highlights the importance of adapting training to each runner.

Why is Trail Running different from Running?

Trail running is a sport that combines a passion for running with a love of nature. Unlike running, trail running involves facing irregular terrain, steep inclines and variable weather conditions. If you are thinking of participating in a 15km trail run, it is crucial to prepare your body properly to avoid injury and improve your performance. In this article, I will guide you through key strength and resistance exercises, how to structure your first training sessions. And provide you with an initial training plan so that you can tackle your first mountain race with confidence. We'll also give you a calendar of races in Spain, France and Switzerland, and give you practical tips to help you get the maximum enjoyment out of the experience.

Trail running presents unique challenges that differentiate it from running on asphalt. Firstly, irregular terrain, such as rocky trails, roots and mud, requires greater balance and stability. In addition, steep inclines require greater leg strength and adapted running technique. In fact, according to a study published in the Journal of Sports Sciences, trail runners experience 20-30% more impact on their joints due to irregular terrain, which increases the risk of injury if they are not well prepared.

Another big difference is the variability of pace. In running it is easier to maintain a steady pace, whereas in trail running, the pace fluctuates due to elevation changes and terrain conditions. This requires greater cardiovascular and muscular endurance. In fact, a study by Loughborough University (UK) has even pointed out that trail runners have a higher aerobic and anaerobic capacity compared to road runners, due to the variability of the terrain.

Key Strength and Endurance Exercises for Trail Running

To prepare for a 15km trail run, it is essential to incorporate strength and endurance exercises into your training plan. These exercises will not only improve your performance, but also reduce the risk of injury. In future posts, we will go into more detail on each of these exercises, offering specific advice on how to maximise their benefits.

However, it is important to keep in mind that every runner is different, and what works for one may not work for another. Therefore, it is crucial to adapt strength and endurance exercises to your physical characteristics and level of preparation. So, in general, these tips may work initially, but as you progress, it is recommended that you consult professionals to design personalised plans based on your needs. 

Strength Exercises

  • Sit-ups: Strengthen the quadriceps, glutes and stabiliser muscles. They are essential for improving leg power, which is crucial for tackling climbs in trail running.
  • Step lunges: Improve balance and leg strength, while helping to prevent knee injuries.
  • Step-ups: Simulate the movement of climbing slopes. This exercise is especially useful for strengthening the muscles used in climbing.
  • Plank: Strengthens the core, which is essential for maintaining good posture on uneven terrain. A strong core improves stability and reduces the risk of lower back injuries.

Endurance Exercises

In addition, we also point out several endurance exercises that in general any trail running beginner should do; although, as we have pointed out in later phases, these exercises should be personalised and designed by a professional.

  • Long runs: Do one long run a week, gradually increasing the distance to 12-14 km. This will help you build endurance. Long runs are essential for improving aerobic capacity and muscular endurance.
  • Hill intervals: Run uphill 200-400 metres at a brisk pace, followed by a gentle descent to recover. Repeat 4-6 times. This type of training improves anaerobic capacity and leg strength.
  • Fartlek: Alternate periods of fast and slow running for 30-45 minutes. This type of training improves aerobic and anaerobic capacity. Fartlek is especially effective for improving endurance on varied terrain.

How to Structure Your First Training Session

If you are completely new to Trail Running, it is important to start with a progressive training plan. Here is a basic structure for your first training sessions:

  • Week 1-2: Focus on terrain adaptation. Do 2-3 short runs of 4-6 km on easy trails. Include strength training twice a week.
  • Week 3-4: Increase distance to 6-8 km and start incorporating hill intervals. Continue with strength training.
  • Week 5-6: Do a long run of 10-12 km and increase the intensity of the intervals. Add core and balance exercises.

In future posts, we will take a closer look at how to structure your training according to your level and goals, giving you personalised advice.

Training Plan for a 15 km Trail

Here is an 8-week training plan to prepare you for a 15km trail run. This plan is designed for beginners and combines running, strength training and active rest. However, it is important to remember that every runner is different, and this plan is only a general guide. For a personalised plan, don't hesitate to consult a professional.
