This is a very beautiful poem, with the subject matter in hand. Though, I have a few notes I want to make. Your rhyme scheme changes over the course of the poem, from a A A B B count to a A B A B count, then to A B B A, and finally back to A A B B. I don't know if this is intentional or not, as it could be interpreted as the changing forms of friendship that you had with the track team, in which case expertly done. If not, just keep an eye on that for future poems.
