So far I've been able to ride on 4 out of a possible 8 days of bicycle commuting, which is sort of pathetic, but I anticipate being able to ride more frequently in the coming days. So far I've logged 42 miles (14 miles round trip to work), burning an estimated 1400 calories, saving myself $23.60 in driving costs (calculated using the AAA estimate of 56.2cents/mile). Gone are the days of being able to ride a "century" in a day, but hopefully this summer I'll get myself back into a condition that's close.
