Critical descents

Descent destroys knees and ankles more than climbing destroys legs. Two days demand serious attention.

Trail Day 11 · Return

Trekking poles + good ankle support are non-negotiable on Trail Day 11. 6,870 ft of descent in one day. Don't skip the poles to save weight.

Speak up early

If you have symptoms, tell your Crew Leader or an advisor. Pushing through silently is how serious AMS happens. Treatment is straightforward when caught early — descent, rest, hydration.
