I went for a lunchtime ride today, my first for February and first in a month, which was due both to bad weather and work overload. I did just 4 miles to see how it was going to go, and it wasn't pretty. I've lost a lot of fitness and didn't have much to start with!
This happens to me every time - I get into a good exercise groove for a few weeks, work gets too busy, and I end up back at square 1. This time it's going to be different, and I'm determined to start bike commuting (25 miles round trip) in March. This will take some discipline and coordination with my wife to make sure mornings with the boys go smoothly with me leaving a bit earlier. My car (used 90% for commuting) reports my average commute speed to be 22 mph over several months, so going by bike won't be that much slower, even at my pathetic speeds.
