Perfect temp for me, about 62F. Just enough to work up a bit of a sweat, but not get really hot on the way in (it's only 4.3 miles, but it's almost all up hill). Going to be in the mid 90s this afternoon for the ride home, which is rare around here, but I love it! Biking to the gym after work, then biking home from there to start what should be a great weekend.
