Training tips
- 1.Back-to-back runs (Sat + Sun) simulate the accumulated fatigue of ultra racing
- 2.Work on your uphill running speed — that's what differentiates trail performance
- 3.Train with race-day nutrition: 80-90g carbs/hour from the start
- 4.Recovery is as important as sessions — sleep, stretch, eat well
- 5.Test your race gear under real conditions during long runs
Frequently Asked Questions
How do I go from finisher to performer on a 50k trail?
The key is working on uphill running speed and anaerobic threshold. Add 2 quality sessions per week (hills + threshold), progressively increase long run volume, and add back-to-back runs (Sat/Sun) to simulate accumulated fatigue.
What's the right run/walk ratio on a competitive 50k?
On a competitive 50k, you'll run ~75-85% of the time depending on the profile. Climbs above 15% grade are power-hiked at a sustained cadence. The goal is to run all flat and downhill sections at a sustained pace.
How do I avoid hitting the wall on a 50k trail?
The "wall" comes from glycogen depletion and/or overheating. To avoid it: start slower than planned for the first 2 hours, begin fueling in hour 1 (60-80g carbs/h), hydrate consistently, and manage your heart rate.
