I have a few points:
1. 4hrs could be ran still however for most people they walked a good part of it, I'd think this could be a HUGE accomplishment for someone who is disabled in someway or highly unoptimized for running (eg, 60+ pounds over weight)
2. this time was mostly for guys a 4:10 mararthon for any non runner is pretty ood and a 4:10 for even some irls that run would be fine, 4:25 is probably an equivelent girls time.
