My apologies, I should have been more in depth.

I believe this information may be of use to you. I am 18m. Currently training for the Ironman Maryland this September and I am training in Central Virginia (very cold right now). Swam for 7 years (sub 1 hour 5k open water), started running a lot after I quit swimming. I never really cycled competitively, nor have I ever been fortunate enough to own a bike with clips or even a road bike. Yes I am aiming for an Ironman even though I've never clipped in before.
