Where are you in Florida? I have a group of buddies (we're all business owners) that work out hard if you really want to get in shape.
We do shit like century rides, half mile swims, 5 mile running races some mornings, wind surfing, mudruns, and we're going to be one of the many teams doing the Spartan race later this year (having just done the Warrior Dash).
FWIW: I'm 5'11", 175lbs. Ecto/Mesomorphic all day, everyday so I doubt I'll ever look like a Spartan who'll eat a Persian for breakfast. More like GSP, but not as famous or rich as GSP. lol
Hey, I'm in the Tampa area.
All sounds like loads of fun, I'm going to focus on getting myself able to do physical activity for more then 15 min and then I'll deff hit you up.
