This morning my knees are aching and my quads are incredibly sore thanks to an excursion up to the Keyhole on Longs Peak. I got a leisurely start, arriving at the trailhead around 9 am and started up feeling pretty good. After an annoying encounter with a horse train, the way was clear up to Chasm Junction where I stopped before. I could see individual climbers on the Diamond pretty clearly from there. I headed off to Granite Pass which went very quickly and then the Boulderfield was in sight. After a bit of rock-hopping, I was at the Keyhole by 11:15. While I would have liked to get the summit, it was at least an hour away still and I had to be back in Boulder. So back down, more or less uneventfully, to the car by 1 pm, a slow time induced by not quite enough to eat and dehydration, a state which persisted well into the night.
To do this mountain fast requires a lot more food and water than I carried yesterday but I think I have learned my lesson on that point. I look forward to a proper summit attempt soon, hopefully under six hours round trip. I will post pictures once I figure out how to download them from my phone.
