If his second half of the race was as strong as the first, he should be able to go 24.5 + 26.5 = 51.0 If he can go sub 23.0 this year and his endurance was in place, he would be on pace for sub 50.0. Having gone sub 53.0 already, it will be interesting to see how much he can tighten up his second split. Keep us posted, and good luck.
