I pulled out my Renn disk wheel and rode 44 miles today. Not the best terrain for a disk as most of it is quite hilly, but both I and the wheel held up well. Unfortunately, the wheel is no longer really true and it has a slight wobble. I am not sure if this can be fixed. It isn't too bad and there is no rubbing -no brake adjustment needed. That is good because the Griffen frame is very tight and there is very little room in the back. The chainstays are almost as close as the brake pads.
It took me 2:44 to cover the distance. I rode out Redwood, to Moraga, to Lafayette (lots of traffic lights here) to Orinda over the St. Stephen's bike path, and then over Wildcat and Grizzly back home. I added a little detour on Grizzly to Skyline at the end. According to the Ergomo I burned 2,065 calories. My average power was 195W with a "normalized" average of 244W.
I felt a bit tired and think I will only do a short run tomorrow. Then I will be on travel for the next three days. That should give me plenty of opportunity to recover.
