I just biked up Western Drive...in the middle of the night because it was there.
Of course, now I'm shaky and nauseated. And my fingers, neck, and lower back are sore.
But I biked from sea level up to the USCS arboretum on my single-speed without stopping. Gotta be a couple hundred feet, anyway. [Edit: Research tells me I went about 320 vertical feet up in a mile and a half. That's only halfway to upper campus. Better keep trainin'.]
God, I'm going to hurt in the morning. I hurt now.
