Essex Triathlons - Hanningfield Reservoir

The Essex Triathlons take place at Hanningfield Waterside Park, located between Billericay and Chelmsford. The event utilizes the 870-acre reservoir and its surrounding mature woodland, featuring a course that includes open water swimming, cycling on country roads, and running on scenic trails. There are no cut-off times for the participants.

The multisport event offers several distance options and disciplines:

  • Sprint Triathlon: 750m swim, 25km cycle, and 5km run.
  • Standard Triathlon: 1500m swim, 38km cycle, and 10km run.
  • Sprint Aquabike: 750m swim and 25km cycle.
  • Standard Aquabike: 1500m swim and 38km cycle.
  • Open Water Swim: Distance details are provided separately.

The swim takes place in the reservoir, where wetsuits are generally recommended for buoyancy and comfort. The cycling portion consists of either two laps for the sprint distance or three laps for the standard distance. The run course follows a lap-based format with one lap for the sprint and two laps for the standard distance.

Participants have access to a secure transition area where bike and race numbers must match the assigned racking spot. The event uses live chip timing to provide real-time results. Finishers receive a medal, merchandise, and refreshments. Free parking is available on-site, but dogs are not permitted at the location as the reservoir is a designated Site of Special Scientific Interest (SSSI).
