Two reasons off the bat: I was wearing my nearly falling apart sandals, and I didn't bring any water. I fought anyways, and was actually making good progress until mother nature decided to help with the lack of water thing. I was halfway up the mountain road (16 kms along the road, at an elevation above 1600 m) when it just began totally pouring. Strong winds blowing too, so any further would have been stupidly dangerous. Especially given I was totally partched.
