13.74 miles of mountain biking. The weather was so nice today. I had to get out on my bike since I can't run. I don't think I've gone mountain biking in December before. At least, not on trails. I rode a big loop that I have never done before because some of it was on some pretty new trails. I rode up Oak Hollow from the Draper pool to the Bonneville Shoreline Trail. I left the BST to ride Ann's trail--which I rode once from the other direction. I took that all the way over to Corner Canyon Road--which I attempted to ride down to ghost falls, but upper CC road is made of clay that gathers like a snowball on your tires when it is damp. Pretty soon, I had so much caked on that my wheels stopped turning. I had to turn around an walk back up the road and take the Rush trail down. Then I took the Shoreline Trail back over along Mike Weir drive and then descended on Spring Hollow and took Vestry Road back to the pool. I made it all the way up and around without stopping to catch my breath. I stopped a couple of times from technical mistakes or to let oncoming riders pass, but I never stopped from fatigue. That has never happened before. And that is exactly why I can't afford to stop cardio training. That will go very fast and I don't want to lose that. I guess I need to ride stationary bikes at a gym or do a rowing machine if that doesn't put too much stress on my hamstring. It was a tough ride and I feel a little beat up, but it was great to get on the bike again. Lots of fun. Training Peaks |
