You do realize he's claiming to be setting an all-time record and is not just a random e-statter on a message board, right?
If I say on a message board that I've run an 11 minute 5k, that's different than if I'm trying to get official recognition for a world record, don't you think? But I guess it's your problem if you don't believe my world record 5k, not mine.
No! This not like running 12:28 for the 5K. This is just some fastest known time for some stunt, lacking rigorous rules or monitoring.
Although there might be a space in here for some sort of cutting tongue-in-cheek mention of those Chinese womens'mid-distance records from semi-mythical Chinese races.
