Today was super muggy, and it was pretty hot this afternoon (27C). I was sweating buckets today, but it still felt great - an awesome end to the first week of cycle commuting for me. 3 days on the bike this week, and I've already lost 1.5 kilograms. Can't wait to keep going - just need to get an adjustment on the rear derailleur, switch to my clipless pedals, and get the headset tightened up a little (noticed a slight wobble today) and I'll be all set for next week.
