Training for a 50 km Ultra: Your Complete Guide

Understanding the Challenge of Ultra Running

Training for a 50 km ultra is no small feat. Whether you’re stepping up to this distance for the first time or looking to improve your past performances, there are several key considerations.

One of the biggest challenges is avoiding the trap of doing too much too soon. Your body needs time to adapt. Pushing too hard early on can lead to injury—a setback that’s best avoided at all costs. This is where load management comes into play. It’s about finding the right balance between effort and recovery. This allows for steady progress without overloading your body.

The Importance of Load Management

On the trails, no two kilometres are the same. You need a system that accounts for those climbs and how fast you ran down them. Ascend was built for trail runners. Our load management metrics—like Running Impact—account for those fast downhills and the stress they place on your body. Running Impact helps you build fitness without overdoing it, allowing you to stay strong and injury-free.

Customising Your Training Plan

Your training plan should be designed around your current abilities—not how fast you were a year ago, but where your fitness is right now. As your fitness evolves, your plan should evolve with it. To achieve this, we create a fitness profile based on your last 6–12 months of Strava data. From there, every workout and progression is tailored specifically to you. This ensures that your training remains both effective and sustainable. No templates or guesswork—just the right training load for you, at the right time.

The Role of Community in Ultra Running

Finally, it’s incredibly valuable to have a supportive community around you—like-minded people on a similar journey. Ultra running isn’t just about the miles; it’s also about everything else that comes with it. Having others to share advice, experiences, and lessons learned can help steady your nerves. This can prevent you from making the same mistakes they once did.

You can ask questions directly to the Ascend community—from world-class athletes to back-of-the-pack runners. Questions always crop up, and someone’s always there to help. The trail running community is one of the best parts of the sport, and we’ve made sure it’s baked into your training experience.
