Now, I don't really believe that. But at least a few people probably do, which is more than ever believed the 4 minute mile was impossible until after the mythology was written.
So, I challenge all the world's top MD runners. The sub 4 mile was a foregone conclusion long before it happened, so the hype and glory was a lie. Set things to rights by chasing a barrier that maybe, just maybe IS impossible! Even if the record is soft, knock off two seconds and you will be legend forever.
And if you succeed, maybe the kilometer will get the respect it deserves. Really nice distance. Thousand meters. Power of ten. Standard unit for road races.
