Intro

The Running Channel’s Taking On The WORLD’S BEST Ultra Runner | Pau Capell Sets Running Channel Challenge has plenty of lessons. Here are the essential details so you can attempt this workout when you’re ready. Watch the full video for complete context.

Key points

• The challenge: cover the 12.2 km (7.6 mi) Ultra X125 England section within 2 hours, or push harder and try to match Pau Capell’s elite 50-minute split.
• Terrain: the first 3 km climb steeply (Jacob’s Ladder), then it flattens to a technical trail section. Plan for heat exposure, significant elevation (466 m), and sparse water.
• Practical tips:
  • Start at a measured pace (target 2 h) and adjust as the terrain and your body dictate.
  • Drink often from the start. Bring a bottle or scout water stops before the first checkpoint.
  • Track your progress with a running watch or the Pacing app, monitoring pace, heart rate, and distance.
  • Don’t get caught in the comparison trap. Run your own race.
  • Dress for warm conditions, apply sunscreen, and secure your eyewear.

Workout example

12-km trail challenge (12.2 km, 466 m gain):

1. Warm-up: 5-10 min easy pace on flat terrain.
2. Segment 1, uphill (0-3 km): aim for a steady climbing pace (around 10-11 min / km) to save energy for what comes next.
3. Segment 2, rolling/technical (3-8 km): pick up to a sustainable effort (around 6-7 min / km), with balance and technique over uneven ground.
4. Segment 3, downhill (8-12 km): run the descent with control, around 5-6 min / km, without sacrificing safety.
5. Cool-down: 5-10 min recovery jog and stretching.

Goal: complete the 12.2 km in 2 hours or less (averaging around 10 min / km) while staying fueled.

Closing note
