What is a Duathlon Exactly?

Duathlon is a multisport event for athletes of all abilities. It’s similar to triathlon in that there are three legs of the event. Unlike triathlon, there are only two disciplines are involved. While triathlon is a swim-bike-run event, a duathlon is a run-bike-run event.


The Ideal Endurance Challenge For Beginners

Whether you’re a new athlete that just signed up for your first race, or you’re a triathlete looking to mix up your event calendar – duathlon can be an exciting multisport challenge.


Sprint distance duathlons are excellent introductory events for those who want to try their first multisport event. All it requires is a little motivation and consistent training.


Similarly, they can be a wonderful challenge for experienced athletes as far as improving their time and working their way up the podium.


What are Duathlon Distances?

Distances vary depending on the location and race organizer.

Most duathlon events are considered sprint-distance events, with each run in the 1-3 mile range and the cycling leg around 8-15 miles. A typical event might look something like this:

  • 1.5 mile run

  • 12 mile bike

  • 3 mile run

Sometimes, though, both run legs are equal distances. It's also worth noting that some races may be categorize as Super Sprints when the run legs is less then 2 miles and the bike is under 10 miles.


Duathlon Event Breakdown

If you’re thinking about doing your first duathlon, you might feel a little nervous about the logistics. Take a deep breath, though – once you brush up on the race-day format and rules, you’ll feel confident about tackling your first race.

Here’s a step-by-step breakdown of a typical Duathlon race day:


Pre-Race Set Up

When you first get to the event, you’ll want to set up your gear in the transition area. This includes racking your bike and adhering your race numbers to the proper spots (typically on your bike, helmet, and shirt) if provided by race organizer.

First Run

The event begins with running, and this may be a mass start or a wave start depending on the size of the event. Most duathlons in the U.S. are mass starts, meaning everyone begins the race at the same time.

If it’s a wave start, groups of athletes will start in a staggered format (typically with a minute or two between each group). For very large events, wave starts help prevent congestion in the initial few minutes of the race.

Once you start, just move those legs and find your stride! Remember to push yourself but avoid overexerting yourself during the first run. You still have two more legs of the race after this!


First Transition (T1)

For T1, you’ll run into the designated section of the transition area and head to your bike. As soon as you reach your bike, put your helmet on first. This is a best practice to make sure you don’t accidentally forget it and have to go back, wasting time.

Once your helmet is on, you can switch into cycling shoes if you’re using them. Then unrack your bike and walk it (not ride it) out of transition.


Bike

Once you exit the transition, you’ll find a designated area to mount your bike. Do not get on it until you reach that area. It likely donated by a tape or special line in the road/pavement letting you know where it is.

Once on your bike, you’ll ride according to the race route. While it is technically your responsibility to know the course, local races almost always have plenty of signs or volunteers to guide you at the turns. You’ll also probably have eyes on other athletes and be able to follow them too.


Second Transition (T2)

As you finish the bike leg, there will be a specific dismount area located outside of the transition area. Be sure to get off your bike here – you do not want to ride into transition.

Once off your bike, walk it into the transition area and re-rack it in the correct spot. Now you can remove your helmet. If you wore cycling shoes during the bike leg, switch back into sneakers for the next run leg.
