So I'm not sure what to do about that. Maybe it was a mistake using MMR - can only one app at a time use the phone's GPS? I asked Google, but couldn't find anything about it. I'm thinking I'll try a treadmill run again tomorrow and see if I get a more consistent reading than I did two days ago. If not, I'll run outside again on Thursday and take the same route, but won't turn MMR on.
One thing remained the same - keeping my heart rate between 135-145 bpm is hard! Just like Sunday, I felt like I was pretty much just speedwalking by the end of my run.
I know the other big component of using this approach is nutrition. I'll be starting his two week carbohydrate restriction test on Saturday - conveniently after I go to Mickey's Christmas party at the Magic Kingdom Friday night, and before a few other holiday parties occur. It's perfect timing, so no excuses for me to fall off the wagon!
