The last time I was around for the double loop in 2022, it was a balmy 40 degrees by the time the ride was underway. The Gatorade flowed freely. My feet and hands were warm. I wore a wind vest and arm warmers. It felt like early spring in Maine. If I had been asked to identify a single, simple, cycling-related and personal measure of how the climate has changed over the past twenty years, this would have been it.
