You might also be able to find an inexpensive used wetsuit to purchase in your triathlon club's classified ads.
Of course you can purchase a new wetsuit as well. This is the way to go if you have an inkling that you will fall in love with the sport. Or perhaps you've already fallen in love?
In any case, you need to do at least one practice swim, and preferably more, in the wetsuit before race day. Wetsuits change your body position in the water and simply feel different. During practice, you will find out if there are any hot spots or areas where the wetsuit rubs into your skin. Additionally, practice quickly taking off the wetsuit, like you will on race day. Lubricating your body with a stick-type body lubricant, a vegetable spray or an ointment helps the wetsuit peel off easier.
Common ointments, such as Aquaphor, can be used on the hot spots to prevent rub marks and blistering.
So, the wetsuit is only for the swim while the tri suit is worn under the wetsuit and is your primary garment for the entire race.
