Clickbait but I will bite anyway.
It is not that hard a question. Going into the race at indoor nationals 11 of the 16 participants had better lifetime PRs than KT and 15 had run faster this season. Did not help them at all. KT was able to run with Wayment and Chelangat who have lifetime PRs under 15:20. Plus you have to look at whether a race is tactical or not. A 15:30 in a race where you had 200m splits as high as 42 seconds is an excellent time and indicates a high PR potential. I thought her race at the ACC championship was the best she ever looked up to that point based on how she closed regardless of the final time. That 15:41 in a slow developing race was more impressive to me than her faster high school record race. Winning in the NCAAs depends on closing speed.
Based on degree of difficulty (solo effort vs. pacers and drafting until the finish line, 200m track vs. 400m track, etc) I thought Tuohy's 15:37 was the most impressive of the recent record runs. I think Hutchins and Cooks races were more comparable given that Hutchins had to run the final half of the race from the front of cooking recipes. The fact that KT was 15 is an bonus.
I thought if Katelyn ran the 5000 at Boston and not the 3000 she would have broken 15:20 there and taken the U20 in the 5000. Right now I think she can run 15:10-15 in a fast race, and possibly below 15:10 if she got into a pro race and was being pulled along. Not going to happen though. She will get a qualifying time and try to win the 5000 outdoors in another tactical race.
Dear leo, both are good players. But i think katelyn will have the upper hand here. She is a distance runner and has exceptionally good conditioning. In fact she is one of the best women runners in the world right now. She is also smart enough to pace herself well in the race. As for cook, she is well known for her speed. But she will be struggling with the longer distance. They both should be the favorites to win, but i think Tuohy has a slight advantage here.
