I was recently asked to write a letter of recommendation for a young women that I coach for a sport. I am aware that she is a good student, however my only interaction with her is through coaching. She is an Olympian and I have coached her since she was a child. I have never written a letter of recommendation. Several of the colleges she is applying to have an online portal where the "letter" is to be written. How might I transform my knowledge of her as an athlete to be of interest to ( -U.S.) colleges ?
Update/Edit: She was excepted into a US service academy and stepped away from the Olympic Games. With respect to the Olympic Games and the training therein all she said was "it was trivial and easy, like seriously really." Indeed it is curious this "trivial introspection" despite years in which she felt she was constantly failing to preform. I now believe similarly to academicians, world class athletes see problems and problem solving differently than does the ordinary person. In particular, upon retrospection world class athletes tend to see problems as trivial and straightforward at either first glance or upon delivery of solution.
