Wetsuit Question

I would be careful in using a wetsuit not intended for triathlons.  I am not familiar with how windsurfing wetsuits are constructed as far as thickness of neoprene and flexibility in the arms, but that is certainly something to look into.  If the suit isn't constructed to swim in, it could quickly become unenjoyable!

How long is your swim? Will you be using this wetsuit for your tri as well or just to try out a wetsuit before the tri and using a tri-specific wetsuit for the event?  I highly suggest renting a wetsuit made for triathlons for your event if you haven't considered this yet. This is a really affordable alternative to buying a suit and can some stores allow you to use a portion of the rental charge toward the purchase of a wetsuit if you decide you want one later.

Body glide is an anti-chafe balm that comes in a 'deodorant stick'  You should be able to find it anywhere tri stuff is sold.  Some bike and running shops will carry it as well. I beleive body glide's website has a retailer look up http://www.bodyglide.com/).  I apply it where I might have chafing from movement while swimming (neck area, around my arm pit area, etc) as well as areas I want to minimize the wetsuit sticking when I take it off (legs and wrists). My only pointer for putting on/taking off a wetsuit is to make sure your fingernails are short and avoid contact with them and the neoprene.  Your fingernails can easily cause a tear in the suit if you aren't careful.
