I had to double-check this to make sure it was real. On Friday night (May 27), Joshua Cheptegei will attempt to break the 5,000m world record at the Pre Classic. Then on Saturday afternoon (May 28), there will be a totally different -- and loaded -- 5,000m featuring Selemon Barega, Moh Ahmed, Paul Chelimo, Jacob Kiplimo, Marc Scott, Berihu Aregawi, and more.
So you've got the Olympic champ racing a bunch of lights for a record he already owns instead of against a field with the other four Tokyo 2020 5k/10k medalists. It's ridiculous. Just put everyone in the same race. Keep it on Friday night so conditions are good and anyone who wants to go for the WR can go for it.
Personally I would rather just see Cheptegei race all those guys without going for the WR.
