The Accenture World Triathlon Mixed Relay will be hosted in Nottingham on June 7 and will be the first opportunity for athletes to gain Olympic qualification points.
Prospective Tokyo Olympians will take to the water of the River Trent to swim 750m then to the streets of Nottingham’s Victoria Embankment to cycle 18km and run 4.5km.
Team GB athletes will compete in the event to gain the first points up for grabs in the qualification process for Tokyo, before they take on the Leeds individual version of the event over the following weekend.
Qualification for spots in the individual triathlon is now determined by a combination of relay and individual rankings.
An early win for Team GB could put them, as a team and as individuals, in a good position to be ranked within the top seven in the world for when qualifying closes in May 2020.
Team GB are yet to announce the athletes that will compete.
Over 15, 000 fans turned out to watch when Nottingham was introduced to the relay version of this sport as it hosted the British Triathlon Mixed Relay last September.
Performance director Brendan Purcell said: “Great Britain has had a lot of success in the mixed relay and we are really excited about the prospect of sending our best possible team to Tokyo as this discipline makes its Olympic debut.”
There is also a schools event, taking part in the morning, then the amateur mass participation race will start at 16:30, with the elite race starting at 18:36, precisely.
The grandstand sold out for the British version of this event last year, but there are still tickets on sale for the world event this year.
Tickets are £17.50 for adults and £13 for concessions.
