PS. Analyzing the situation, my eyes were bigger than my stomach. Was excited (too excited in this case) to go out fast. About 90 seconds in I realized the split was not going to be negative. What happens then is how long can you hold the pace without crashing and burning. Fun stuff. You’re having fun too, right?
If you are looking for creative ways to play games with yourself, in any form or function, to stay motivated with exercise, one of my favorites is running negative splits. Say you run one mile. The second 800 split will be faster than the first 800 time. This is very difficult to do when your pace is fast, but sissy-easy to do when you stroll for the first half.
