Was running the New York City Marathon back in the 90's. Just dying the last few miles; made the turn into Central Park from 5th Avenue up that short steep hill (no longer part of the course, they took it out to make it easier), and started walking up the hill.
A woman runs out of the crowd, gets in my face and yells "I didn't come out hear to watch you walk!!". I started jogging the rest of the hill and when I crested it and was out of sight, I went back to walking slower than I was going up the hill.
