World Triathlon Corporation, owners of the Ironman and Ironman 70.3 Series, announced modifications to several rules and regulations relating to the swim portion of triathlons in the U.S.

It will certainly be interesting to see the ramifications of this new ruling.

Effective September 1st, 2010, which is the start of Ironman’s 2011 competition season, new rules for apparel and wetsuits will apply at all Ironman and 70.3 events in the U.S., including both World Championships. The amendments were made to further standardize rules in the Ironman/70.3 Series and ensure a fair playing field at events around the globe.

The changes include the following:

– Swimwear and swim apparel must be comprised of 100% textile material, such as nylon or lycra, and may not include rubberized material such as polyurethane or neoprene.
– Swimwear may not cover the neck or extend past the shoulders or knees.
– Swimwear may contain a zipper.
– A race kit or trisuit may be worn underneath swimwear.
– Wetsuits cannot measure more than 5 millimeters thick.
– Wetsuits may be worn in water temperatures up to and including 24.5°C/76.1°F.
– Athletes who choose to wear a wetsuit in water temperatures exceeding 24.5°C/76.1° F will not be eligible for awards, including World Championship slots.
– Wetsuits will be prohibited in water temperatures greater than 28.8°C/84°F.

“Ironman recognizes the importance of showcasing the competitive element at all events. We believe these amendments place more emphasis on performance and function and less on technology, therefore staying true with the Ironman spirit,” says Ironman’s Head of Officials, Jimmy Riccitello.

What is particularly interesting is that the Ironman’s rule changes are consistent with rule changes adopted by swimming and triathlon’s international governing bodies, FINA and ITU, respectively.
