The HM record might go down in Saudi Arabia in Februari one of the next years if they keep putting up rediculous prize money like they did in the inaugural this year. They want an event that rivals Dubai. They got the money to invite bigger names to make it happen as word gets around. $267'000 to the winner FIRST year was just an insane warm-up. They got the resources to give that to Kipchoge for apperance alone, and a couple of millions on top should he break the WR.
