Broken clouds today & unusually humid for our region. Really worked up a sweat. On my morning commute I got onto South Bay Road & began overtaking what appeared to be a child on a mountain bike. As I caught up, I realized it was a very small woman, standing on the pedals & moving along at a pretty good clip. I think I frightened her so I turned off & took a different (longer) route to Martin Way where I spotted her up ahead of me still standing up & hammering away. She turned off towards St Peter's Hospital still standing & riding hard. If she had been on a road bike she would have really been moving. Don
