This traffic-free race circuit with its own self-enclosed swim lake is the UK's No1 venue for elite triathlon competition.

This round of the Super Series is a two-stage format, with the heats taking place on Saturday afternoon/evening and the finals on Sunday morning.
In addition, all athletes will be entered to take part in a short Mixed Relay held on Sunday after the Finals. Teams for the mixed relays will be organised through regional coaches. 

In a change from previous years, the Saturday heats will take the form of draft-legal races.
The results from the heats will provide the seeding for the A and B (and C for the Open category) finals on Sunday morning, which will be a draft-legal, mass-start format.
Gear restrictions, where appropriate, will be applicable in both the heats and finals of the Youth races.

The distances will be as follows:
Youth A/B
Saturday Heats : 350m swim - 6km bike - 1.5km run (draft-legal, mass start)
Sunday Finals : 400m swim - 8km bike - 2.0km run (draft-legal, mass start)

Junior/Senior
Saturday Heats : 350m swim - 8km bike - 2.0km run (draft-legal, mass start)
Sunday Finals : 400m swim - 10km bike - 2.5km run (draft-legal, mass start)

Mixed Relay
Distances : 200m swim - 3.2km bike - 600m run (draft-legal, mass start, relay) 

The swim will be a single lap of the lake that fills the interior of the racetrack.
The transition will be in the hard-standing paddock area.
The bike will use a 2km anticlockwise lap of the super-fast bike circuit. 
The race finishes with 2 laps of a flat, tarmac, out-and-back run lap .
The bike and run courses both pass the spectator area each lap to enable the athletes to receive great support.... so don't forget your cheer squad!

Course maps are available via the menu above.

Registration will open from 12:30pm on Saturday, with racing starting from 3pm. Detailed start times will be included in the Athlete race guide. 
It is estimated that the Mixed Relay will finish by 2:00pm on Sunday.

Entry for this race is open to athletes who are participating in the Super Series and have received an invite to enter by British Triathlon. These will be sent out from the British Triathlon Pathway team from June 10th.
