Am I allowed to post that my almost 30 year old daughter can still rip? She won the season's woman's trophy in her beer league. In spite of being really sick for four of the meets, and missing two of the eight races.
(She got that horrid flu that leaves you coughing for weeks and cracked a rib from the coughing. I wish I could say she was better now.)
As to dropping out of racing, she stopped after freshman year of college because she wanted to concentrate on college and felt she couldn't do both and succeed in both. But, it turned out she never really left the sport because her old team asked her to coach when they heard she'd moved back after college. So she did that for five seasons (with an interruption for grad school). She's done with that now, but doing this beer league thing, so in a way she didn't leave.
