Notes
Treadmill at workout anytime. Forgot to turn off GPS on the 310xt so stopped the treadmill and started it again. However, I did not deduct the time. These results are from the 910xt anyway.
Temp 72 with humidity of 59 so TdP is 128.9
I reduced the run time by a minute to make up for having to stop and restart the machine. It looks like 5 mph = 12 minutes per mile gave me a heart rate of 108/109 for future reference. So, I could have sped up a bit, but I had the neighbor's dogs to take care of and also they didn't have MSNBC on, only Fox news, and I hadn't bothered to ask them to change it. So, I only did a couple of miles. It was pouring outside.
