I hate to throw around a stereotype but my experience with triathletes is most of them are blind. They'll run over a California Redwood and feed it to whoever is drafting them. Add to that the choppy, start/stop pedaling (especially on slopes), abrupt speed changes and you've got yourself a great chance to find out what your medical co-pay is. I don't care who drafts me because nine times out of ten, I'm not the one who's going down. However, I'm very choosy about taking a wheel from someone I don't know.
