I learned my lesson at the marathon nationals to not put in too many miles/hours on the bike the day before a race. Today I opted for my Public D8 cruiser bike for getting me around the city. I've got some slight modifications I'd like to do for a more aggressive ride, but otherwise it's perfect for hilly San Francisco.
Tomorrow is the Tamarancho Dirt Classic up in Fairfax, CA, just 3o minutes north of where we live. I'm excited to do this race since it's so close to home. While I'm not expecting to do spectacularly well, since my focus is on marathon, and I'm just not that explosive off the start line. My game plan is to be conservative on the downhills while attacking as much and as hard as possible on the climbs, knowing it's a rather short 21 mile course, consisting of three laps.
