Cotswold 113
Next Race: 06/06/2027
Lake 32 Outdoor Centre, Spratsgate lane, Shorncote, Cirencester, GL7 6DF
Cotswold 113 is our middle-distance triathlon set in the heart of the Cotswold Water Park, starting and finishing at Waterland Outdoor Pursuits (Lake 32), Ashton Keynes.
A 1.9km lake swim, a two-loop bike route out through the Cotswold lanes, and a three-lap run finishing back at the water's edge all run under British Triathlon non-drafting rules, with the option to race solo, as a Relay Team, or as Aquabike/Bike-Run.
This is a course built for a big day out: still lake water for a calm swim start, wide open Cotswold roads, and a course team that genuinely wants to see you smash a new PB.
Whether it's your first middle-distance start or you're chasing a qualifying time, this is the event to find out what you're made of.

Run — three laps finishing right back at the water's edge, 21.1km in total, with well-stocked aid stations throughout.
Relay, Aquabike & Bike/Run
Not racing the full distance solo? Enter as a Relay team and split the swim, bike and run between you, race Aquabike for a swim/bike-only day, or take on Bike/Run with a flexible start window.
All formats race alongside our solo triathletes, each identified by a different coloured bib.

Run to British Triathlon non-drafting rules, with full event medical cover and a marshal team out on course all day to keep you safe, on route and cheered on.
