I've done shorter runs with friends, but never over 5K. Pat and I ran the Don River/Distillery route today, which is 5.13K. Poor Pat, he's a much faster runner than I am, so I told him to go on ahead. He was able to run the stairs up to street level four times while waiting for me! :D It was a good run, and I pushed myself at the end with a sprint. Whoot!
