IRONMAN Triathlon Wetsuit Rules

Ironman Triathlon Wetsuit Rules Swim

There are a few key things to remember when it comes to the IRONMAN triathlon wetsuit rules. First and foremost, the rules are updated annually and come into effect after March in Africa, America, and Europe, and after July in China and Oceania. This is to ensure that all athletes competing in international races are on a level playing field.

Secondly, while the specific rules can vary slightly at some events due to local rules, Ironman tries to standardize wetsuit rules across all events.

The IRONMAN triathlon is one of the most challenging and demanding races in the world. To complete the race, athletes must swim 2.4 miles, bike 112 miles, and then run a marathon – all without taking a break.

To make sure that everyone has a fair chance to complete the race, there are some rules regarding the use of wetsuits. Here are a few:

  • Wetsuits may be worn in water temperatures up to and including 24.5°C/76.1°F.
  • The maximum allowable thickness for a wetsuit is 5mm.
  • Neoprene or any other booties are prohibited unless the temperature of the water is 18.3°C/65.0°F or colder.
  • Wetsuits are mandatory if the water temperature is below 16°C/60.8°F
  • Gloves or any hand cover are not allowed. 



USAT Triathlon Wetsuit Rules 

Orca equipe triathlon wetsuit men

The USAT Triathlon is the national governing body for the sport of triathlon in the United States. It sanctions races and regulates athletes to ensure fair competition. It also offers coaching certification and training programs to help athletes reach their potential. The USAT Triathlon also puts on events such as clinics, camps, and seminars to educate the public about the sport of triathlon.

In order to participate in a USAT-sanctioned event, athletes must comply with the following wetsuit rules:

  • Wetsuits may be worn during any USAT triathlon event, except where prohibited by the race director.
  • The maximum thickness is 5mm for a wetsuit.
  • Competitors may wear wetsuits if the water temperature is 78 degrees or lower.
  • Competitors may wear wetsuits but will not be eligible for awards if the water temperature is between 78.1 – 83.9 degrees
  • Competitors aren’t allowed to wear wetsuits if the temperature is 84 degrees or above.


Triathlon Swimming Wetsuit FAQs

Triathlon wetsuits are a high-dollar item that requires some level of research and understanding. Here are some of the most frequently asked questions in the space. 

sleeveless triathlon wetsuit in open swimming temperature

Do wetsuits make you faster in triathlon?

For athletes of all swim calibers, a wetsuit can provide significant improvements in both speed and efficiency. While the potential benefits are highly individual, the influence of buoyancy and hydrostatic lift offers practical advantages for triathletes. 

A more buoyant vessel enables a more streamlined position that keeps swimmers horizontal with the water. This added lift allows swimmers to glide faster and more efficiently. Published studies have highlighted particular wetsuit benefits for inexperienced or poor swimmers as well as lean individuals with low body fat.(1)

So, how much faster is a wetsuit for triathlon swimming? Depending on the level of the swimmer, tests have shown time savings between four and ten seconds per hundred meters. There are many reports of wetsuit speed gains providing an average of 10 percent or one minute per kilometer. Evan Morrison tested his sleeveless wetsuit and achieved speed improvements of 7.3 percent and 55 seconds per kilometer.

However, it’s worth noting that a triathlon wetsuit with sleeves is generally faster than a sleeveless one. This triathlete’s test of several different wetsuits showed the Blueseventy Helix to deliver the fastest speed gains. The Helix was also highly reviewed by Ironman athlete Ben Greenfield for its buoyancy and feel. Ultra swimmer

What type of wetsuit is best for triathlon?

Today’s top-rated triathlon wetsuits are designed with specialized paneling and strategically-displaced neoprene thicknesses to optimize buoyancy in the torso and legs while maximizing stretch and flexibility around the shoulders. This enables optimal efficiency for open-water swimming and primarily utilizing the freestyle stroke.

Some of the best triathlon wetsuits that deliver on these features include:

What is the difference between a triathlon wetsuit and a normal wetsuit?

Triathlon wetsuits are vastly different in comparison to traditional wetsuits used for surfing, scuba diving, and other watersports. The main differences center on the wetsuit’s material composition, design, and fit. 

Like most wetsuits, triathlon wetsuits are primarily made of neoprene. But what makes them different from normal wetsuits is the type of neoprene and the coating applied to the outside of the suit. Most high-performance triathlon wetsuits use a premium-grade Yamamoto neoprene with an SCS (or equivalent) coating to maximize the slipstream effect in the water.

In addition to the type of neoprene, most of today’s top swimming wetsuits are strategically designed to displace greater neoprene thickness in the torso and upper legs (specifically the bottom-facing part of the body when in a freestyle swimming position). This engineering is intended to increase buoyancy in targeted areas where it matters most for triathlon swimming. Conversely, a thinner neoprene is used around the neck and shoulders to maximize flexibility and reach during the freestyle swim motion.

Lastly, triathlon wetsuits have unique design considerations that emphasize fit and ease of removal. They often come in a multitude of sizes to ensure an optimal fit for athletes. And because triathletes often obsess about every second saved in when transitioning from swim to bike (T1), tri wetsuits are crafted with easy-to-use zippers and quick-to-remove ankles and sleeves.

What is the best thickness for a triathlon wetsuit?

The optimal thickness for a triathlon wetsuit largely depends on the athlete and the type of water their swimming in. But in general, utilizing the maximum allowed wetsuit thickness of 5mm is preferred to maximize buoyancy, and therefore, swim speed and efficiency. 

Most of today’s best triathlon wetsuits use neoprene thickness paneling to improve buoyancy while optimizing freestyle swimming. For instance, some wetsuits will feature a 5mm thick torso but only 0.5mm to 1mm thick shoulders. Keep in mind that USAT and Ironman-sanction triathlons limit wetsuit thickness to 5mm maximum.


What water temp is wetsuit legal for triathlon?

The rules that govern wetsuit-legal water temperatures vary depending on the event and governing body. 

USAT Triathlons

Most local triathlon use USAT wetsuit rules which allow athletes to wear a wetsuit if the water temperatures are 78 degrees Fahrenheit (28.5 degrees Celcius) or lower. This rule only applies to competitors who wish to be eligible for awards (athletes can still wear a wetsuit in water temps above 78 degrees, but they won’t qualify for overall race results.)

For elite athletes racing USAT, the wetsuit policy is different. The maximum wetsuit-legal water temperature is 68 degrees Fahrenheit  (20 degrees Celcius) for swim distances less than 3000 meters and 71.6 degrees F (22 C) for distances of 3000 meters or greater. This policy is determined by the USAT Athletes Advisory Council.

Ironman Triathlons

For Ironman events, including 70.3/half-Ironman distance triathlons under the Ironman brand, the rules are slightly different. Professionals and age-group athletes are allowed to wear wetsuits if the water temperature is 76.1 degrees Fahrenheit (24.5 degrees Celsius) or lower. Any temps 76.2 F or more and wetsuits are not permitted.

Additionally, wetsuits are mandatory for Ironman professionals and age-group athletes when water temps are below 60.8 degrees Fahrenheit (16 degrees Celsius). Wetsuits are also prohibited in water temperatures greater than 83.8 degrees Fahrenheit (28.8 degrees Celsius). These rules are designed to help protect the safety of athletes.
