Waves set by your swim lanes
The number of pairs per wave follows the lanes you have, and the schedule builds itself from the entries. With a wave every five minutes, an evening of sixty pairs fits in about two hours.
Hybrid racing
The hybrid race, in a swimming pool
Stations on the pool deck, a swim between each one, pairs starting in waves. Here is what to plan when you are the one running it.
The format has been spreading through aquatic centres since 2025 under names like Aquarox®, Swimrox® or Hydrox, and more than twenty pools in France have already run one. It takes the HYROX® idea and swaps running for swimming, most often eight fitness stations on the pool deck with a hundred metres of swimming between each, in pairs. For the organiser the bottleneck is no longer the station but the swim lane. The lane sets the wave size, the start rhythm and how many pairs one evening can take. Throwdown handles registrations, waves, timing and standings, and the name of the evening stays yours.
What to keep in mind
Pairs, solo and levels
Men, women or mixed pairs, solo, a beginner level and an advanced one. Each division has its own price, standings and minimum age, with a parent’s consent for minors.
Waterproof chips as an option
Active waterproof transponders, worn at the ankle on a neoprene strap and read as athletes leave the pool. The 600 € pack includes the finish sensor, forty transponders and Throwdown ticketing.
Every swim counted
As a 300 € option, a sensor at the pool exit counts each pair’s crossings. A missing swim adds the penalty you set to the time, with no one keeping count by hand.
Live standings, with or without chips
Without equipment, each pair’s time is typed in from a phone. With chips it comes in on its own. Either way the standings show on the pool screen and on the athletes’ phones.
Nothing to pay if the evening is free
A free entry costs nothing and needs no payment account. On a paid entry it is 3 % plus 1.50 € per registration, paid by the athlete by default, and the money goes straight to your account.
-
A race that alternates swimming with fitness stations on the pool deck, rower, SkiErg, wall balls or burpees. The most common format links eight stations with a hundred metres of swimming between each, in pairs, with a beginner level and an advanced one. It runs under names like Aquarox®, Swimrox® or Hydrox, and in English it is often called a swim fitness race.
-
As many as the swim lanes set aside for the race, often four to six. The teams per wave setting fixes it, and a wave every five minutes gives the one before time to clear the lanes.
-
Yes. They are waterproof active transponders, the same ones used in triathlon, worn at the ankle on a neoprene strap. They are read when the pair leaves the water and crosses the line.
-
Yes, with the 300 € swim count option. A sensor at the pool exit counts each pair’s crossings. You set how many are expected and the penalty for each missing one, and the standings account for it on their own.
-
Yes. Free registrations cost nothing and need no payment account. To sell entries online, a privately managed pool, a club or an association gets paid straight into its own account, and a council run pool checks how it collects public revenue with its finance office.

A name that belongs to you. Aquarox® and Swimrox® are registered trademarks of their owners, and a name of your own is easier to find in Google, edition after edition.
