I’ve been off the bike for 2 weeks, and this might have been a bit ambitious given the circumstances. I did pretty well until 55km in and then I just had to stop, too tired to keep going. I might have sat around for 15-20 minutes before I could get back on the bike. By that time Rene had looped back around to check on me. He graciously trailed me all the way home to make sure I made it as I limped back another 10km at 20-24km/hr. Thanks Rene!
