Afternoon run was just a little extra work to try and push the body's endurance a little more. Wasn't sure how far I was going to go. It was hot (95 degrees) so I just wanted to stress the body a bit. Ran 2.01 miles at a 9:14 pace. This was pretty tough, but I felt pretty good afterward. Noticing the Garmin GPS seems to be drifting. I was able to confirm this didn't mess with my results as I was on a track so I knew how far I was going, but a little frustrating. I did some research online and found several people offering advice such as resetting the satellites, resetting the watch, etc. Found a forum post that advised the person having the same problem to give the watch a little more time to calibrate even after it says it has finished locating satellites. The Garmin 310xt would tighten up its location even after it says it was done with this step. Seemed to me that, if you were moving during calibration, this could throw off the Garmin. Will try this on my next workout. Stand still in the open and let it calibrate for a few minutes. I know today, I just turned it on as I was walking from my office to the track so this might have caused a problem. Will report back on this. Looking to do another 2-a-day tomorrow. Probably run and then bike. Working the run a little more lately as I see it as the place where I might find the most improvement time-wise.
