In 10th place was 19 year old Japanese Yuta Shimoda in 2:11:34 (Results here: http://www.letsrun.com/news/2016/02/2016-tokyo-marathon-results/ ). He was totally pumped. He was smiling and pumping to the crowd before the finish. According to Brett Larner http://japanrunningnews.blogspot.com/2016/01/tokyo-marathon-elite-field.html Shimoda was the fastest Japanese 18 year old half marathoner with a 1:02:22.
So that begs the question we get all the collegian freshman in the US and train them for the marathon, what do you think they run?
We should have another thread, what happens if we get a fast course and get all the American to go out at 2:06 pace.
