three hours of sleep, cooler thankfully and I replaced the bike computer for the fixed gear since I'm using it to commute on this summer. I hit 31mph downhill at one point! Averaged 16.4mph for 20 miles. Good enough for me and my pannier laden commuter! I'd love to step up to about 80 gear inches but I don't think I'd make it up the 1 mile hill to work...without heaving anyway.
