Rules of the Game - Wetsuits

Swim Conduct: Wetsuits 

This week's rule is Article 4.4—Wetsuits.

The rule allows participants to wear a wetsuit if the water temperature is 78 degrees or less. The upper limit was set because wetsuits are allowed for protection against hypothermia, and there is little risk of hypothermia for a swimmer in water as warm as 78 degrees.

Beginning in 2013, participants must ensure that any wetsuit used has a uniform thickness of 5 millimeters or less. If the water temperature is between 78 and 84 degrees, a participant may elect to use a wetsuit but is removed from age group competition and rankings.

Here's the rule:

4.4. Wetsuits. 
Each age group participant shall be permitted to wear a wetsuit without penalty in any event sanctioned by USA Triathlon up to and including a water temperature of 78 degrees Fahrenheit. When the water temperature is greater than 78 degrees, but less than 84 degrees Fahrenheit, age group participants may wear a wet suit at their own discretion, provided however that participants who wear a wet suit within this temperature range shall not be eligible for prizes or awards. Age group participants shall not wear wet suits in water temperatures equal to or greater than 84 degrees Fahrenheit. The wetsuit policy for elite athletes shall be determined by the USAT Athletes Advisory Council. The AAC has set the wetsuit maximum temperature for elite/pros at 68 degrees for swim distances less than 3000 meters and 71.6 degrees for distances of 3000 meters or greater.

Effective January 1, 2013, any swimmer wearing a wetsuit with a thickness measured in any part greater than 5 millimeters shall be

20 Triathlon tips for beginners that are new to multisport

Tip to improve your triathlon performance

Whether you’re a seasoned multi-sport expert or a complete triathlon novice, our top 20 triathlon tips will help you get more from your swimming, cycling and running performance.


What is the Biggest Bang For Your Buck when it comes to TT equipment?

The speed you can achieve on your bike is determined by two factors:

1. How much power you can produce
2. Wind resistance. The faster you go, the more wind drag you need to overcome.

A few months ago there was an excellent article in Velonews (Vol 39, No 3) about which aerodynamic equipment benefits most during an individual time trial. What they didn’t do is rank the cost vs. benefit for each piece of equipment and the associated time savings. Years ago I saw something like this done by cyclingnews and found it extremely interesting. Unfortunately it’s buried deep in the internet and is lost forever so I thought I’d rehash it for those of you who missed it.


30 Things Every Triathlete Should Know by the Age of 30

Earlier this week, a Huffington Post article titled  “30 Things Every Woman Should Have and Know at 30” made its rounds among women. Originally featured in a 1997 issue of “Glamour” magazine, the editors are now turning the list into a book, released Tuesday. The post has received 1,500 comments, 32, 000 Facebook posts, and over 4000 Pinterest pins so far.

Being the triathlon devotee that she is, Lisa Barnes, one of our writers here at LAVA posted a triathlon-inspired version of the list on her blog TriMojo today and gave us permission to re-post it here. ”Now that I’m 33, I’m happy to report that I have accomplished nearly everything on this list,” Barnes writes. Her thoughts then turned to her progress as an athlete, and she realized that in triathlon, as well as life, the 30s are the decade in which many athletes start to achieve a rhythm and balance in their approach to multisport.
