I was the only one on the "slower" ride on our Tuesday Evening Ride. When I started off, I found I could/wanted/needed a ride that pushes me. Around ISD I was smokin' (for me and on my mountain bike) at 18-20 mph.
Made my personal best time for shop and around Manawa. Pushed most of the ride - heart rate at 130-150. A real workout. Felt great after the day off yesterday.
