Anyone brave and hardy enough to attempt a triathlon needs to make sure to invest in the proper Triathlon Clothing. An entire long-distance race that just involves running, cycling or swimming would be a challenge enough. But a triathlon which involves all three, makes the choice of clothing even more important than normal, in short, this one is definitely harder.
Even getting through one leg of a triathlon can be a test of endurance and strength, so if you are willing to try this race you really need every advantage that you can to make it through all three legs. It is important that you're comfortable the entire span of the race. And aside from simply feeling cool and comfortable, you also have to protect your skin from things like chafing if you have any hope of finishing the race without being miserable.
When you're looking for the right equipment or suit for running or bicycling, be sure you purchase one that's designed for triathletes and not just casual wearers. You can find such clothing as worn by professionals on companies such as ActivInstinct and The Triathlete Store. A pair of triathlon shorts, for instance, will be designed far better than your average cycling shorts that you can pick up in a discount store. Ordinary cycling shorts are going to be designed to fit well and prevent chafing, but shorts designed for triathletes are designed with the other legs of the race in mind.
