While some training clothing may work sufficiently for race clothing, we don't recommend using "race" clothing for frequent training. The high-tech fabrics used in race clothing are not made for everyday use. Multiple and frequent washing can wear out these high-tech qualities more quickly. Over time, for example, wearing race gear in chlorinated pools can have an impact on the elasticity, hydrodynamic and sunscreen qualities in the fabric. While we recommend testing your race clothing a couple of times before you race to ensure that it fits correctly and won't cause chafing, we don't recommend using it for regular use.
Many of our clothing manufacturers have different ranges of clothing for men and women designed to stand up to the punishment you dole out on a daily basis. The less expensive lines tend to hold up pretty well for training, and can perform decently in a race setting. Triathlon Clothing at TriSports.com
