Takeaway

Smart hill repeats turn steep climbs into a strength engine for any ultra.

What happened

I tried a 4‑week hill repeat program on the 800‑ft climb at Ridge Trail, adding progressive overload each week. By week three, my VO2 max numbers rose and my descent times dropped noticeably.

Why it matters

Hill strength translates directly to faster ascents, safer descents, and lower injury risk on technical terrain. For ultrarunners, the ability to sustain effort on long climbs often decides podium placement.

How to think about it

Start with a conservative volume—4 repeats of 2 minutes at 85% max effort, with equal jog recovery. Add 10‑15% volume each week, and mix in longer, slower repeats for endurance. Listen to your legs; cut back if you feel lingering soreness.

Pros
  • Boosts leg power
  • Improves lactate tolerance
  • Transfers to race terrain
Cons
  • Increases muscle soreness
  • Requires a suitable hill
  • Can be mentally taxing
Watch out

Avoid hill repeats on steep, unstable ground to prevent ankle twists.

FAQ

How often should I schedule hill repeats?

Aim for one session per week, allowing at least 48 hours of recovery between hard efforts.

Can I use a treadmill incline instead of a real hill?

Yes, set the incline to 10‑15% and keep the speed consistent with your target effort, but complement with outdoor hills for technical specificity.

What if I have knee pain?

Reduce the incline and volume, focus on low‑impact strength work, and consult a physiotherapist before progressing.
