Event overview
The Osborne's Grays Triathlon takes place on 19 July 2026 at Blackshots Leisure Centre, Blackshots Lane, Grays RM16 2JU. The event is open to adult and youth competitors aged 15 or older on 31 December 2026. Total places are limited to 200. Options include the full sprint triathlon or alternative formats: Aquathlon (no bike leg) and Aquabike (no run leg).
Distances
- 400m swim
- 20k bike
- 5k run
Course and race format
The swim is 12 lengths of a 33m pool swum in a snake format. Transition 1 is accessed directly from poolside; competitors collect their bike and join the bike route. The bike course is two laps on local roads that remain open to traffic, so normal laws of the road apply and helmets are compulsory. Transition 2 returns competitors to the rack where they left their bike before the run. The run is three laps in the grounds of Blackshots Leisure Centre, finishing close to the transition area.

Standard entry is £50; Aquathlon and Aquabike entries are £45. Early entry until 31 January 2026 reduces fees by £5 for each category.
