i rounded up, going 3.2 miles in and 3.3 miles home = 6.5 miles total. but i have been riding mountain bike last week, taking some short cuts and dirt trails, so distance is total of 6.1 miles with but time increase about 45 min (usually 15 min x 2 = 30 min). in the summer, i add big loops after work with loaded commuter to +/- 12-45 mile rides! good productive form of stess relief!
