Went riding today in the mid afternoon. The weather was warm. Warmer than the last ride. I tried using the Virtual Partner on the GPS. It worked, but really didn't prove useful for the time being. I don't want to make every ride a race, so I'm probably going to opt out on this feature. I cruised the way out, no heroics. I knew I was going to need my strength for the return ascent, which was true. I started at a modest tempo and gradually lifted up the pace as I made it to the top of the climb. So ailments, were actually under control. I had a slight soreness in the right knee, which went away after a few minutes later. The heat is what really got me. I just couldn't lift the pace at the lower elevations. But, it wasn't unbearable. I had to just pace and stay within myself. So, concentration, was ok. Lapses here and there, but I made it back safe and sound. Balance was a little off today, I just kept reminding myself where my body should be shifting. It worked. I'm trying to see how exactly the Gopro is working with the Battery Bacpac. It's a little unpredictable. On my home tests, it locked up a few times. Reseating the battery seemed to fix it. But if I were on the road, I wouldn't want that to happen. GPS, working well, no problem with the gradient reading today.
