premise: I think everyone felt pretty good . I was pretty exhausted before the race even started , having taken my cross bike down the AZ trail from the Rio del Flag area to Lake Mary , down Lake Mary Road back into town through south campus on the urban trail . It 's like 20 miles or so . Why might I have ridden my bike 20 miles before the race even started ?
hypothesis: Walking my bike to the race might have been the only way to get to it .
