I’ve just registered for the SF Marathon. This means that I will be among the thundering herd that starts out at the Embarcardero, crosses (and re-crosses) the Golden Gate Bridge and makes a long, slow parallelogram through the city. A couple of my readers were slightly worried about my doing this, but I’ve trained well (with incremental distance runs and raw-chicken resistance weights.) I don’t expect to have a great time but I’ll do my best (and try not to walk.) This will be my fourth marathon, and my last one for at least the next four months or so. I’m hoping to do two marathons a year from now on if I can.
