I'm not a runner, but I would assume that unless you're already pretty physically fit or have running experience you can't start from scratch and run an ultra-marathon in six months. Full marathon practice sessions weekly for two months! I would reckon being able to recover between those that quickly is a skill developed over years, even if not necessarily from running. FWIW, I think the point was that even if the kid took 2 months of "moive time", the audience perceived that time to be only a few minutes. Two months of solid work is a lot, and I don't think a few minutes of film can do justice to that.
