Why Is Bike Drafting Illegal In Triathlons? And How You Can Still Draft


Bike drafting is a technique all cyclists use to get an advantage by cycling very close to the cyclist in front in order to reduce the air drag.

It is considered to be very advantageous because it offers the drafting cyclists, lesser air resistance and less energy to overcome at the expense of other cyclists while cycling.

Despite its advantages, it has been stated as illegal in the majority of triathlons and is clearly laid in the USA Triathlon rules.

The USA triathlon rules clearly state, “While on the cycling course, no participant shall permit his drafting zone to intersect with or remain intersected with the drafting zone of another cyclist or that of a motor vehicle. With respect to a motor vehicle, it is the triathlete’s responsibility to move out of the vehicle’s drafting zone or to continually communicate to the vehicle to move away.” (Source).

But why exactly is bike drafting in triathlons is illegal? bike drafting is illegal because it creates an inappropriate advantage for the drafting cyclists, helping them save 15 to 30 percent of cycling energy at the expense of another triathlete. This goes against the purpose of the sport, which is to measure individual strength, speed, and endurance without taking advantage of other participants.

With this purpose in mind, the USA triathlon rule also states, “CYCLISTS WHO ENTER THE DRAFT ZONE MUST PROGRESS THROUGH IT AND COMPLETE A PASS IN NO MORE THAN 15 SECONDS.” In simple terms, if you must enter the draft zone, do not sit in it for more than 15 seconds. The same applies to Ironman triathlons

It is important to note that few triathlon organizers allow drafting, like in some of the Top-level International Triathlon Union racing.

Triathlon Drafting Illegal – Why ?

Why Is Bike Drafting Such A Big Deal In Triathlons?

Many other Triathlons particularly in the US frown at the idea of drafting because the idea of triathlon is to “beat the time on your own”.

The forms of Triathlon that do not allow bike drafting are the Ironman events, where the strength, endurance, and fitness of the participants are tested, and whoever emerges as the winner is named “IRONMAN”.

Being named “Ironman” sounds like an award based on individuality

This makes more sense why Ironman triathlete frown at the idea of including bike drafting in their triathlon event.

Another triathlon format is known as the half ironman (70.3), also considers drafting illegal. The half ironman triathlon is similar to the ironman triathlon but the participants cover only half the distance of the Ironman event.

Age group races are also considered drafting illegal. So, the participants are not allowed to profit unfairly from another participant.

How much time and energy do you save from bike drafting?

This is a question everyone keeps asking and a lot of studies have been done on it, which has helped shed some light on the aerodynamics of bike drafting.

Based on the study done by Chester R. Kyle, bike drafting helps to save over 30% of energy while cycling and helps you gain an extra speed of 0.9-1.8m/s. This occurs because cycling in groups at a middle position helps shield you from the wind by the cyclists behind, on either side and ahead of you. (Source)

The study of how much energy you can save from bike drafting is quite inconclusive, as some studies have shown that bike drafting can save up to 15%-40% of energy, while some studies have said bike drafting saves 27-50% of energy. Nevertheless, it has been proven that bike drafting saves time and energy by some good numbers.

So how much difference does bike drafting make? Triathlete performance in improved between 15 to 30% when bike drafting. This is a conservative conclusion based on the above.

Why is Bike drafting allowed in top-level International Triathlon Union?

The top-level international Triathlon Union, ITU is a governing body that hosts the world triathlon series which was established in 1989. The ITU has a long history of earning the triathlon sport, a spot at the Olympics.

Comparing Swim Vs Bike Drafting

No doubt, water is denser than air, so it is much easier and comfortable to draft while on a bike than to draft in water.

More energy is conserved while drafting on a bike than in water. Instances of discomfort that could occur could be, when the drafting swimmer, swims close to the lead swimmer. Such that, the feet of the lead swimmer could cause serious harm to the face of the swimmer behind.

Also, while drafting in water, it might be difficult to see due to the enormous amount of water that might hit your face plus the kicking feet of the swimmer in front. There is a chance that this could cause some type of discord in the water between the swimmers.

Despite the discomfort, it is still advisable to draft during the swim leg of the triathlon so you have a chance of getting ahead, especially in bike draft illegal races.
