SWMA Tri Evening series 2026
The SWMA Tri Evening series runs from May 13 to October 14, 2026, at Cromhall Quarry Open Swim Centre in Cromhall, Gloucestershire. Events take place on the second Wednesday of each month and are based at the open water swim venue near M5 junction 13. Registration is closed for this listing.
The series features a sprint triathlon and a new duathlon option. The triathlon uses open water swim, on-road cycling laps, and an out-and-back run finishing around the lake. The duathlon begins with a short run and then follows the same bike and run legs as the triathlon.
Distances:
- 750 m open water swim
- 18 km bike (3 laps of 6 km)
- 5 km run (two out-and-back legs, finishing around the lake)
- 1 km run start for the duathlon
Wetsuits were mandatory for the 11th May event and are optional for the remainder of the series depending on water temperature. The event provides free parking and is chip timed. The series is organised by Trimax Events and uses the Cromhall Quarry Open Swim Centre location and surrounding roads for the course.
