Legs have felt spent after a weekend of plane and car travel and some weight lifting sessions. Saw three people on the ride home last night which was nice even if I didn't get to say hi. Up early to do my first ride as a commuting mentor for the local transit authority. Strange experience. I've led many group rides for recreational cyclists but we're out in the country with no stop lights or traffic and it's easy to keep track of everyone. Commuting, I'm so focused on traffic and staying safe and used to being alone, it's difficult to maintain a reasonable speed, hold a good, unobstructive line and call out turns and hazards.
