I lapped a 2.5 K loop four times to cover 10 K today.
I cruised along the course three laps at a very comfortable pace
to check my running form.
I then stopped by home to take a pee break before the 4th lap for about two minutes.
Then after that I cranked up the pace for one last lap to finish.
1st 2.5 K: 13:14.56
2nd 2.5 K: 13:29.68
3rd 2.5 K: 12.58.87
4th 2.5 K: 10:35.70
Total 10 K: 52:38.41
