HeatWave Aquathlon 2026

Date: Sunday 5th July 2026

Hello and welcome to our HeatWave event page!

The HeatWave Aquathlon is our new event held in the same location as the popular long running Frosty Aquathlon which is held annually in March. Being July we hoping for lighter warmer climbs for our participants! The headquarters of the event, and location of the pool swim is The Littlehampton Wave. (postcode BN16 2NA) on the West Sussex south coast.

The swim is in an 8-lane 25-metre pool – the run course is a loop around Mewsbrook Park before heading out onto the seafront promenade.

Whilst some of our entrants have previously participated at the Frosty Aquathlon, this event is open to anyone willing to take part.

This event is proudly sponsored by

THE RACES

We offer two distances:

• The HeatWave:      800m pool swim and 10k run – Minimum age for participation is 17
• The MicroWave:  400m pool swim and 5k run – Minimum age for participation is 16

Entries will be available online only – no on-the-day entry. The closing date for entries is Sunday, 28th June 2026.

The entry fee for both races are the same.

• £35* for BTF members
• £43* for non-BTF members, which includes the £8 purchase of a British Triathlon Race Pass

(* excludes ResultsBase registration fee)

The entry fee for both races is the same, but if you are not a member of the British Triathlon Federation (BTF), you must purchase a British Triathlon Race Pass, which costs £8, providing relevant insurance. The link to purchase a race pass will be provided upon entry.  Their full terms and conditions for Race Pass are shown here. People who are not UK residents will need to purchase their own insurance through their home country federation or personal insurance provider.

Alongside your entry fee, we are asking whether you would like to make a small donation to Cancer United, a local cancer charity, a cause close to our members’ hearts and continues to be our club’s designated charity.

Registration is at 6.10am with the first wave of the HeatWave setting off at 7.00am. The swim is in a 25m Pool and we have experienced lane counters to count your lengths. The run is well marshalled and takes in a circuit around the local boating lake before heading along the seafront promenade. The course is flat and, if your training has gone well and the weather is kind, fast. Individual and team winners are usually announced and presented with their prizes at around 10.30am.
