I'm used to feeling rotten the first twenty minutes or so, but today I didn't start to feel better until I'd been running for nearly an hour. At that point I was at Crissy Field, a treat as I'd never been there before. The landscape varied from sand to marsh to grass and there were lots of interesting birds - pelicans, egrets, etc. About 80 minutes in I was actually picking up speed and feeling strong.
But that sun was relentless, and I had brought neither hat nor sunscreen. I was wilting. With the Ferry Building endpoint in sight my knee started to ache, for the first time since I started running again. Uh-oh, that's what lead to doom and several non-running years before. I managed to finish, but was careful.
Two hours thirty-two minutes. Mentally calculating for a ten-mile run, I thought that despite the heat I had actually picked up speed from last week. But double checking the course with Google Maps indicated I really had only gone about 9.4 miles, so I'm still above 16 minute pace.
I revisited the race site and read that the course will be open to everyone for 6.5 hours; half and full marathon runners start at the same time. I still expect they will start reopening roads during the race though, so I really need to pick up speed. Right now however I'm sticky and sore and exhausted.
