A couple months ago, I was in a 40 mile (4 laps) race where about 38 out of 100 riders did not finish the race. I completed the race and finished last about 20mins behind. I was behind far enough that when I finished, the next wave of riders were already starting. If you were in that situation, would you have continued the race and finish last or just bail out in the middle when you had the chance and DNF.
