halo-evan canyon-keystone canyon. 63, cloudy, breezy. got down to 8:30 pace, averaged 9:30 through keystone @ the end. was running as hard as I could. my legs felt like they were going to seize up or something. I think i'm just fucking old for this. i'm whipped. at least I finished a long run for once.
