Also this weekend
The same event also offers a Sprint distance (750m/25km/5km) and a longer 'Odyssey'-branded middle distance (1.5km tidal swim/86km bike over 3 loops of the Dengie Peninsula/20km run over 4 estuary laps), plus Aquabike and 2-3 person relay options across distances.
Sprint
This event's own shorter distance, at the same tidal venue.
Odyssey (Middle Distance)

Wetsuit mandatory
Below 14°C a wetsuit is compulsory for a 1500m swim under rule 4.2(a).

Where Big East Triathlon starts and finishes
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on. The official course map is the one to use: view it on the organiser's site .

Race Day Info & Checklist
On the day
- The swim starts beside the Byrhtnoth statue, a memorial to the Battle of Maldon.
- Hosts the 2026 East Region Adult Race Series.
- The longer "Odyssey" middle-distance option takes in scenic Dengie Peninsula and estuary views.
- A self-service feed station on the Big East (Odyssey) bike loop has water and gels — organisers recommend carrying your own supplies regardless. The run has feed/water stations at around 2.4km and near transition.
- Athletes starting a run lap after 8:00pm must carry a light or torch, given fading daylight — this is a real consideration on the longer Odyssey distance.
- Transition towels are capped at 30x30cm, rolled in your shoe; bikes are racked by the saddle with the front wheel facing you. No changing facilities, only portable toilets, with a couple of privacy tents in transition.
- Aquabike finishers have their time stop on entering T2, then walk or run unofficially to the main finish for their medal.
