It took 90 minutes before I felt comfortable- toes got quite chilly, but 51 miles and 3:08 later, I was home, feeling good, feeling thankful, and very hungry. I'll post a Polar chart of the ride later on, if the mood strikes. Avg HR was 155. My race form is clearly kaput- I'm re-building base fitness. Nine days off the bike when I had the flu the other week, really hurt what little form I had left.
