I am curious how their two kicks stack up. I would not automatically give the advantage to Lagat. Lagat has shown that he is no longer the miler he once was. On the other hand, Rupp is a guy with pretty good speed but hasn't had the endurance to fully utilize it in the past. He is getting stronger though, as his 26:48 last summer/fall indiciates. I would pick Lagat if it's close at the end, but I wouldn't be surprised if I was wrong.
I think Lagat will come in with one strategy: sit and then kick the last lap. Rupp I am not sure. I think the first 2k will be slow, then Rupp might choose hammer the last kilometer. If I was Rupp I might think about checking over my shoulder at 2400; if Lagat is there back off and then surge again with a quarter to go (if not, just go for it). I think it is unlikely, but POSSIBLE, that Rupp might try to sick and kick on Lagat. Call me crazy, but if Alberto likes what he sees in practice, I can see this MAYBE POSSIBLY working.
