18 minute miles for 40 days. It boggles the mind.

Keep in mind the average walker does 20 minute miles so it is barely faster than walking but still, 40 days. I've done marathons and I wouldn't walk for 40 days unless my life depended on it.

This story reminds me of that one guy with an actual "superpower". He has the genetics where his muscles can actually burn lactic acid as fuel. So he has impossible endurance. Dean Karnazes - has run 350 miles in 80 hours (13 minute miles). He's done 50 marathons in 50 consecutive days.
