He has a huge stride, which I am not convinced makes him a smooth runner, neither is it necessarily more efficient but I leave that as a question for those with more expertise. I am not sure that he can beat the freshman from Wisconsin who is only about 15 months older than he is. Ahmed, was the first freshman at NCAAs and that came with a very late start to training. He ran about 14:15 last year in the heat to win Pan Am Juniors.
Why is he a class year behind his grade level - language?, is he slow (or was early but not now, which happens)?
