Event summary

Get ready for an unforgettable day of athleticism and camaraderie at the ATW Big East & Maldon Triathlon, taking place on Sunday, September 21, 2025, in the picturesque town of Maldon, Essex. Organized by ATW, the UK’s largest triathlon organizer, this event promises a fantastic experience for both participants and spectators alike. Athletes will have the chance to compete in several exciting race formats, including the challenging Middle Distance Triathlon featuring a 1.5km tidal river swim, an 86km scenic bike ride, and a 20km run. For those looking for something shorter, the Standard and Sprint distances are perfect options, as well as Aquabike choices for athletes who prefer to skip the run.

The race kicks off at 12:10pm, with registration opening at 10:30am, allowing plenty of time for athletes to soak in the atmosphere and connect with fellow competitors. Participants will enjoy the stunning backdrop of the Dengie Peninsula as they navigate a non-draft legal bike leg through charming villages, followed by a flat 5km run that showcases the beautiful promenade. With a commitment to inclusivity, ATW welcomes athletes of all backgrounds, ensuring a vibrant and supportive race

Organiser's Description

The Big East & Maldon Triathlon is brought to you by the largest triathlon organiser in the UK!

JOIN US ON THE AFTERNOON OF SUNDAY 21st September FOR A GREAT EVENT EXPERIENCE DELIVERED BY TRIATHLETES FOR TRIATHLETES

The Big East is a Middle Distance Tri involving a 1.5km tidal river swim, an 86km road bike and finishing off with a 20km run.

Alongside this fantastic Middle Distance event you can also choose to take on the usual distances of a Standard (1500m swim, 40km bike, 10km run) or Sprint (750m swim, 25km bike, 5km run) Triathlon.

With the race starting in the afternoon, we encourage athletes to stay behind to socialise with fellow athletes.

Anyone who doesn't want to take part in the run, there is a middle and standard distance Aquabike (swim-bike) option and for those who would like to compete as a team, there is a middle distance relay option, with or 2 or 3 individuals sharing the disciplines between them.

In order to time the start with the high tide, the race will begin in the afternoon at 12:10pm with registration opening at 10:30am.

Due to the tidal flow, the swim leg has a strict cut off time of 1hr 10 mins, and the overall event a cut off of 8.5hrs to ensure everyone finishes in daylight.

The swim uses a 750m swim course (that was new for 2023), starting next to the imposing statue of Byrhtnoth, celebrating the Saxon Battle of Maldon, and heads out towards Northey Island.

This event has a non-draft legal bike leg that takes athletes out of Maldon and onto the quiet, scenic roads of the Dengie Peninsula through the villages of Latchingdon, Tillingham, Steeple and Mayland. 

The run course is a flat 5km loop that heads out and back on the promenade before taking the footpath along the sea wall, and heading back towards race HQ. The last kilometre is completed looping around Promenade Park where spectators will get a great chance to cheer you on.  The surface is a mixture of paved roads, grass and gravel track.

Transgender athletes are, and will continue to be, very welcome at recreational and competitive activity in Triathlon.

At any competitive event from 1st January 2023, there will be a Female category open to athletes who are the female sex at birth and an Open category open to all other athletes.

Not only will you earn yourself this fabulous medal,  there will also be goodies waiting for you at the finish line!
