I'm signed up for the intermediate length. This will be my first Atlantic swim. I've done Sarasota a couple times but that's a fresh water lake. I scheduled this one because I want to be able to (legitimately) say I've done triathlons "coast to coast". In fact, I plan on doing coast-to-coast this year. I'll do Key Biscayne in March and Santa Barbara again in August. (I'm getting to where I hate Santa Barbara. I don't know why I keep going back.)
