But First, Tri for Joe

Two weeks after St. Anthony's and one week after the Flying Pig half marathon, I am back for serious training. My focus now will be to get ready for the half ironman in August.
But first we head down to Coney Island (the one in Cincinnati) for Tri for Joe. This race benefits the Down Syndrome society and last year had about 500 participants.
Lucinda, accross the street, is involved and tells me that 400 have signed up so far.
The race starts with a .4 miles swim in this giant pool. The water was just put in and is running around 60 degrees. So my big question is whether to wear a wetsuit or not

Pro--Warmer during the swim
Con--Takes time to get off after the swim

Time vs Comfort? which way to go?
