Subject: RE: Ironman Arizona : Official Threadmax - 2010-07-10 9:40 PM A lot of it depends on what you're accustomed to. When I lived in New England, I swam several 1/2 IM swims in 56 degree temps with just a sleeveless suit and had no issues. After the first 3-5 minutes in the water, it was comfortable. But if you don't habitually swim in those temps, yeah, it might be a shocker, especially over long disances. Yup  A lot of it also has to do with how long you plan on being in the water. |
