8 Miles on the Bike

Bob and I took an 8 mile ride this morning. We were going to change out my bike seat, but the one I bought wouldn't work. Before we left, we checked the air in my tires, only to discover that they were missing about 40 pounds! No wonder it's been so hard to ride. I feel pretty silly.
The difference in the ride today was unreal. We're going to get the tubes changed so I'll be in good shape for the balance of my training and the TRI.
After the ride, we walked for about 12 minutes.
