A while ago I did a voice-over interview for a video that the St. George Marathon was producing for the 35 year anniversary of the race. One of the questions was "What is going through your mind toward the end of the race?" I responded that during at least one part of every race I think to myself "This is the stupidest hobby ever! I am never going to run again." Of course those thoughts all evaporate by the time I reach the finish line.
Incidentally, that was one of the comments that was included in the video. Watching this gave me goose bumps. Their video is EXCELLENT.
Be honest, is it just me? Do you have some point during a race when it starts to hurt and you question your sanity for ever getting into running?
