Trek day 5 (and high altitude strengthening exercises!)

7M; walk 7M and 1 hour strengthening exercises
Altitude 16,500ft

Again, no space for a safe run. But I added in five cycles of Runners World strengthening exercises (each cycle consists of: 15 single-leg squats; 24 hops; 15 single-leg reaches; 10 plank-alternate leg lifts and 15 Y-squats).

I didn’t realise quite how high an altitude we were at until later and perhaps would have given them a miss had I known. Still, I only had a mild headache overnight. No other ill effects.
