I just did the hike up to Kuelap near Chachapoyas in Peru. Only 5 hours but probobally the hardest hike I have done, in the swealtering heat with NO shade. I wouldn't have got through it if it wasn't for Aphex Twin giving me a beat to march too.
Yr lucky you didn't break a leg if you were marching to the Twin's beat
I have to say that even though I'm a massive music fan, when I'm out in the wilds I just want to tune in to the natural sounds
