Hybrid racing

The hybrid race, in a swimming pool

Stations on the pool deck, a swim between each one and pairs starting in waves.

Talk about my project See the platform

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.

For organisers

Pool races on Throwdown

Throwdown brings together on one platform everything a hybrid race in a swimming pool needs, from registration to the live leaderboard, with waterproof chip timing on quote. The format, the prices and the name of the evening stay yours.

  • Online registration

    Tickets by division, payments straight into your account, promo codes and a waitlist. A free entry costs nothing.

  • Pairs, solo and levels

    Men’s, women’s or mixed pairs, solo, beginner or advanced. Each division has its own price, places and leaderboard.

  • Waves sized to the lanes

    The number of pairs per wave follows your lanes, and the schedule is generated from the entrants then adjusted at check-in.

  • QR code check-in

    Every athlete gets their QR code by email, and the welcome desk scans it from a phone to mark who is there.

  • Waterproof chips on quote

    Waterproof active chips worn at the ankle, read as athletes leave the pool, and an optional count of every swim.

  • Times entered without equipment

    Without chips, each pair’s time is entered from a phone, and the leaderboard updates with every finish.

  • The leaderboard on screen

    Finishes and standings show live on the pool screen and on the phones of athletes and spectators.

  • Messaging with athletes

    A message to every entrant or to one, with a notification on their phone, for a wave time or a last minute change.

  • Invoices and visuals

    An invoice in your organisation’s name for every entry, and visuals ready to post on your social accounts before, during and after the evening.

When you create the competition, pick the “Hybrid race” discipline, then set your divisions and the number of pairs per wave.

What to keep in mind

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.

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 pack includes the finish sensor and Throwdown ticketing, on quote.

Every swim counted

As an 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 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.

Create the competition and pick the Hybrid race discipline. You then set your divisions, your prices and the number of pairs per wave, and open registration. Waterproof chip timing is added on quote, with a reply within 24 hours.

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.
