So I had to do my run at the gym today because had an IBS flare up last night and did not feel like running. Anyway I don't know if I had it on too low a setting but it was so much easier than my usual run in outdoors. I'm going to assume its because it keeps you at a steady pace as I feel I have a tendency to speed up a bit but did not like it at all. Found myself running in the 5 minute cool down just to fell like I had done something.
So looks like I'm going to be sticking to the park!
