Participated in 2010 Bike the Drive for my third consecutive year. Starting at the Fairmont Hotel, I took Columbus to Randolph to the path beside the Cancer Survivors Park (a total of 1.0 miles) to the starting point at Jackson and Lake Shore Drive. Heading north on LSD, I rode to the northernmost point of the loop at Bryn Mawr Avenue (rest stop); rode back to start/finish (rest stop); then rode to the southernmost point of the loop at the Museum of Science and Industry (rest stop). I then rode north to the turn-around at Fullerton Avenue and returned to Grant Park. Temperatures were in the mid-60s at the ride's starting time of 5:30 a.m., quickly warming into the 70s by ride's end. Light winds from the southeast. Skies were mostly sunny with perfect temperatures. I wore new style Livestrong jersey and black shorts.
