The way back up took way longer than the way down.
Almost at the top, where "almost" is more than two hours. I
finished around 10pm, going very slowly since I was out of breath
too often (it is pretty high).
The end of more than 20km of walking, with an additional 1km down
and then up (Tony had about the same distance but an additional 500m
vertically). Brought back memories of basic training... Still, I
wished we'd do more.
