I&#39;ve only recently returned to swimming after two years of doing only cycling. I have about 10 weeks to train foren-USTelligent Community 12https://community.usms.org/thread/262619?ContentTypeID=1Fri, 06 Jul 2007 08:42:32 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:e060a6f7-6fa0-4764-81e0-9bd0ca8e5d0aMuppetSarge, Everyone&#39;s got different criteria. For me, it is a function of the distance and the body of water. If you told yourself 3 years ago you could do it w/o the wetsuit, I vote for sticking to your guns. Think of how bad your feelings will be hurt if you break a promise you made to yourself ;) Paul&#39;s right - its just a mile! Good luck! :fish2:<div style="clear:both;"></div>https://community.usms.org/thread/262562?ContentTypeID=1Thu, 05 Jul 2007 15:22:19 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:0a3693dc-c8f0-43a5-a1c8-cd393d9e9594Former MemberI think its very individual. I did Donner a couple of years ago and it was about 63 degrees. I didn&#39;t think it was that cold until the last 20 minutes. When I got out I was shivering. I didn&#39;t have as much trouble with the cold until I started running a few years ago, and burned off most of my body fat. My bouancy changed, and I started to get cold in the lakes. I guess what I am saying is that the cold can sneak up on you. It is there waiting for you to get tired, or to slow down, and then it nails you. I have not used a wetsuit myself, I can&#39;t afford one. But I think I would want one in the Bay. Advice? I don&#39;t know. If you have a wetsuit, why not try it? If not, well, you&#39;ll probably survive, its only a mile!<div style="clear:both;"></div>
