Not really sure that Bairu is a marathon guy, but Geb struggled somewhat before getting it. He doesn't have the leg-speed to kick effectively in the 10k, so it was a worthwhile (although not productive)experiment. Hopefully there is another race (Hengelo?) where he can qualify.
Mo Ahmed doesn't have the kick either - will he move to the Marathon after College? Levins might stay on the track, or try the marathon as well, since that is where the money is if you run fast enough. He obviously can handle the milege required!!
