If she got special treatment it would be a joke. The only reason she is considered good is because she's running against inferior runners. If you think D3 and D1 are equal, it's because you're ignorant. They couldn't be further apart. I would have been a lock multiple time All-American in D3, but wasn't remotely close to the number 1 guy on my team. He's getting special treatment for three reasons:
1) He went to a school that has alumni who are willing to offer this kind of support. You can get a general sense of alumni support that a program has before you choose it if you really want to, so it's her own fault she didn't pick a school where there are alumni who are willing to put this kind of money into an athlete.
2) He's straight up better than her. In D1, you have absolutely no idea who this girl is. At her best, she's a top 100, MAYBE top 75 girl in the country. Miles is much better than that.
3) He's running for a team. My guess is alumni are more willing to help out on this because his not being there would be detrimental to the team and not just himself. For her, she could choose not to go and it would largely only affect her. If he has to choose, it affects many different people.
On all accounts, Miles wins. He picked the better choice to receive support, and is comparatively a better athlete, and is competing for a team. Easy to see why he gets the plane and she doesn't.
