Well my goal is to spend an hour a night on the bike on weekdays, the fun part is that I keep going farther and farther to get to that hour. I think I hit 55 minutes tonight, but I am not sure since the battery on my Garmin ran out about 40 minutes into the ride. I was a bit intimidating tonight since there were still patches of snow on the MUP. But the new knee did quite well, I only had to stop and oil if a couple of times to get rid of the squeak
