Last modification : 06/05/2025 02:40 PM

Introduction

A triathlon is a multisport competition combining three disciplines: swimming, cycling, and running. This demanding format tests not only endurance but also the ability to transition between events. There are different formats for all levels, from the curious amateur to the seasoned athlete. But why is this sport so successful? It's simple: it offers a complete and captivating challenge. For many, the triathlon is an extraordinary human and sporting adventure. Participants embark on a journey that is as much mental as it is physical, pushing their limits in often exceptional settings. Result: a growing enthusiasm in municipalities and sports clubs.

Strategic Planning of the Event

The distances

When we talk about triathlon, it's not a one-size-fits-all format. On the contrary, several distances exist, suited to all profiles.

  • XS: 250 m of swimming, 6.5 km of cycling, 2.5 km of running.
  • S: 750 m swimming, 20 km cycling, 5 km running.
  • M (Olympic): 1.5 km of swimming, 40 km of cycling, 10 km of running.
  • L: 1.9 km of swimming, 90 km of cycling, 21 km of running.
  • Ironman: 2.4 miles, 112 miles, 26.2 miles.

These formats influence everything: logistics, timing, time barriers, supply needs, etc. It is therefore crucial to clearly define the distance based on your target audience and your organizational capacity.

Define the objectives and the target audience

Before diving in, we need to answer an essential question: why are we organizing this triathlon? Is it to introduce the discipline to a local audience? Attract experienced competitors? Highlight an association or a municipality? According to the objective, the means deployed will be different.

Defining your target audience is also crucial. An event aimed at beginners does not require the same level of supervision as a high-level federal competition. This influences the choice of distances, time barriers, safety requirements and even the sponsors to approach.

Choosing the date

The calendar is a strategic factor. You should avoid overlaps with other major sporting events or school holiday periods if you are targeting a local audience. The ideal? A date in spring or summer, when the weather conditions are more favorable. This makes it easier to manage aquatic safety and attracts more participants.

But be careful: remember to check the federal calendars to avoid competing with other triathlons. And have a plan B in case of bad weather: cancellation, postponement, or route modification. 

Selection of the location and routes

The choice of location is crucial. It must combine accessibility, safety, and the beauty of the setting. Here are the three axes to consider:

Swimming course: A calm body of water (lake, pond, sheltered sea) is ideal. It must allow for the installation of buoys, aquatic safety (canoes, boats, lifeguards), and provide easy access for spectators.

Cycling route: Select well-paved roads, with little traffic, and a minimum of intersections. The closure of roads (via municipal decree) is often indispensable. Also think about signage and marshals.

Running course: Prefer flat, shaded trails if possible, with regular refreshment zones. The goal is to offer a pleasant yet challenging finish to the race.

Obtain the Official Authorizations

Request for prefectural authorization

Organizing a triathlon requires a prefectural authorization. Why? Because you are mobilizing public space, involving the safety of individuals, and potentially coordinating multiple municipalities. This authorization ensures that your event complies with the law, as well as with civil safety requirements.

You need to plan ahead: generally, at least 2 to 3 months before the scheduled date. Prepare a complete file including the details of the routes with maps, the estimated number of participants, the means of rescue and safety, event insurance, and the planned supervision (volunteers, marshals, first aiders...).

Municipal decree and road closures

Once the prefectural authorization is obtained, it is necessary to obtain the municipal decree to authorize road closures and the temporary occupation of public spaces (beaches, roads, parking lots). This allows you to secure the routes, particularly for cycling and running. This order is often discussed in the municipal council, so once again, anticipate.

Coordination with the sports federation

If you want your triathlon to be verified, listed on the official calendar, or allow participants to earn points, you need to collaborate with the French Triathlon Federation (FFTri). This step is often overlooked by novices, but it is essential if you are aiming for a large-scale event.

The FFTri will guide you on the specific regulations to apply, the respect of distances and categories, the presence of official commissioners, and the framework for timing and ranking.

Logistics and On-Site Organization

Management of transition zones

The transition zone is the strategic heart of a triathlon. That's where participants change their gear between disciplines. A poorly organized space can ruin the experience, even causing accidents. It is necessary to provide numbered bike racks, clear ground markings, a smooth transition route, and continuous monitoring to prevent thefts or mistakes. Safety in this area is paramount. Prohibit any unauthorized access, and schedule a specific briefing on its operation during the participants' welcome.

Implementation of time barriers

Time barriers are essential to ensure that the event takes place within reasonable timeframes, both for the safety of the athletes and for overall logistics. They set a time limit for each event. For example:

  • 30 minutes for swimming.
  • 2 hours for the bike.
  • 1h15 for running.

These times should be adjusted according to the distance of the triathlon and the level of the participants. They must be announced in advance and clearly reiterated during the briefing. If a participant exceeds a time barrier, they are stopped or redirected. 

Safety and medical assistance

Aquatic safety is one of the most critical aspects of a triathlon. The risk of discomfort, panic, or accident is real, even among trained athletes. For that, a solid plan is needed:

  • Canoes and paddles along the entire route.
  • Rescue divers.
  • A medical station in proximity to the water exit.

The role of the rescuers doesn't stop there. They must be present along the entire cycling and walking route. Depending on the size of the event, arrange for an ambulance, or even an emergency doctor. The rescuers must be trained, available, and well-distributed. They provide the first aid in case of a fall, heat stroke, or injury. A detailed emergency plan (with access to firefighters and a reference hospital) is required by the prefecture.

Essential Equipment and Supplies

Course marking with markers

Course marking is a key element to ensure a smooth and safe competition. Markers, directional arrows, ribbons, and banners are indispensable. Each discipline must be marked according to its needs:

For swimming, use buoys that are visible from afar, often inflatable and brightly colored, positioning them in a straight line or in a triangle, depending on the layout of the water body. For cycling, the markers should indicate every turn, potential hazards (speed bumps, sharp turns, descents), and the remaining kilometers. And, for running, rely on regular signs, ground arrows, and flags. Also, remember to mark the refreshment areas.

One piece of advice: plan a dedicated team for marking inspection the day before and the morning of the event. A storm or an act of vandalism can throw everything into question...

Electronic timing and scoring

Today, a triathlon without electronic timing is a bit like a marathon without a finish line. Participants want to know their overall time and their time for each discipline, as well as their transitions. The most common system? The electronic chip, worn on the ankle or integrated into the bib. It records the times at each strategic point: start, transitions, finish. The whole system is connected to a central software that automatically calculates the rankings by age categories, gender, format… Make sure to test the equipment in advance, and have a manual backup plan in case of a computer bug.

Bibs, medals, and podiums

Bibs are not just a number: they are used for timing, identification, and safety. Provide a bib with the participant's name or number, a color code according to the format or starting wave, and your sponsors' logos.

As for the medals, they mark the achievement. Even if your event is amateur, offering a "finisher" medal is a appreciated gesture. And of course, plan a real podium with award ceremonies for the winners of each category.

Finish area and refreshments

The finish area should be designed as a welcoming and recovery space with a finishing mat, inflatable arch, music, shaded and resting areas, and a solid refreshment stand: water, fruits, biscuits, energy drinks. 

Registrations and Communication

Online registration

Today, no more managing registrations by hand. An online registration platform saves you a ton of time. You can use Imagina, this platform allows the organizing team to easily manage registrations while optimizing interaction with participants. Thanks to its advanced features, Imagina allows you to create customized registration forms and keep track of all participants' actions. Don't forget to clearly indicate the cancellation policy, the required documents (medical certificate, FFTri license), and the safety instructions.

Communication strategy and sponsors

A successful triathlon is also a well-communicated triathlon. You need to create buzz before, during, and after the event. Use social media (Facebook, Instagram, TikTok), a website or a page on the registration platform, posters in stores, clubs, schools, or articles in the local press.

And above all, think of your sponsors. Give them visibility: logos on the bibs, banners on the site, mentions in emails... In return, they can fund the equipment, the prizes, or the goodies.

Briefing, rules, and categories

Before the start, a briefing is essential. It can be oral (15 minutes before the race) or sent by email in the days leading up to it. It must remind participants of the triathlon's schedule, the functioning of the transition zones, the main rules (drafting-sheltering prohibited on the bike, wearing a helmet, etc.), and the age categories (cadets, juniors, seniors, veterans).

The regulations must comply with FFTri standards if you are affiliated. Otherwise, it is up to you to draft it accurately and fairly. It must outline the penalties (course errors, dangerous behavior), the appeals process, and the schedules to be followed.

D-Day: Total Coordination

Role distribution

Each team member must know their mission:

  • Safety officer.
  • Volunteer Coordinator.
  • Timing manager.
  • Microphone host.

Distribute a clear schedule with the times, locations, and emergency contacts. A WhatsApp group or a radio allows for instant communication between teams.

Communication between teams

Good communication avoids 90% of problems. Plan:

  • Walkie-talkies for key areas.
  • A central coordinator to manage emergencies.
  • Regular checkpoints.

Also think about a central dashboard with all the passage times, incidents, and stock status (water, supplies...).

Conclusion

Organizing a triathlon is an intense, demanding adventure, but incredibly rewarding. Every detail matters: from water safety to course marking, including volunteer management. By following this step-by-step guide, you are now ready to create a memorable sporting event that will leave a lasting impression and enhance your territory.
