Carolyn Hayes has all but secured her participation at the Tokyo Olympics this summer following a 10th place finish at the World Triathlon Championship Series event in Leeds.

The result is Hayes's best performance at World Championship Series level and follows her silver medal last month at a World Cup race in Lisbon.

The final race of the qualifying period takes place in Mexico next weekend but Hayes won’t need to make the journey, such is the security of her grip on the 'Europe New Flag’ position in the Olympic Rankings Simulation.

Hayes ran superbly over the 10km course, covering the distance in 35mins 10secs and finished in 10th place overall with a time of 1:58:16.

The race was won by Maya Kingma in a time of 1:54:26.

Russell White finished 35th in the men’s race and continues to hold the 55th and final spot on the Olympic Qualification Simulation ahead of next weekend’s make-or-break event in Mexico.

A slower than expected swim cost White as it left him in a bike pack that was unable to make contact with the main body of the race for the entire 40km bike.

White ran an excellent 33min 13sec 10km and said afterwards that while the result will not move him up the Olympic rankings, his run and bike performance gives him confidence as he heads in to the final qualifying race.

"It all comes down to Mexico now, but I am still in the driver’s seat and still have that slot. But I think I can’t protect it, I just have to go for it. It’s going to be super hot – in the high 30s so it could come down to a hard messy run," White said.
