Irish triathletes Aileen Reid and Bryan Keane are set to race the Yokohama leg of the World Triathlon Series this weekend.

In previous years the Yokohama course has been infamous for its hot and humid conditions, however, this weekend may suit the Irish competitors with temperatures set to be around 20 degrees.

The course consists of a two- lap 1500m swim with competitors exiting onto a pontoon after 750 metres before diving in for the remaining 750 metres.

Then comes a nine-lap, 40km bike leg with a host of 90 and 180 degree turns making it a testing route which will sap the energy out of competitor’s legs.

Finally, the 23 women and 39 men will tackle the flat and fast four-lap 10km run.

Reid in the women’s race is off first and faces stiff competition from the USA’s fast-running Gwen Jorgensen, who is the bookies favourite to take victory.

Two- time World Champion and Beijing Bronze medallist Emma Moffatt has also been in good form of late as has Reid’s training mate Jodie Stimpson of Great Britain.

Reid’s early-season form has been affected by a knee injury see picked up some months back.

With a number of weeks consistent run training now under her belt, Reid’s run times have been improving with her clocking a 35min 45sec 10km in the San Diego leg of the World Triathlon Series three weeks ago.

A further improvement in run form will see her better her 14th place finish here last year and challenge near the top of the field.

In the men’s race, Keane will be thankful for the cooler water conditions, which will likely result in a wetsuit swim, making his task of remaining in the lead pack out of the water that little bit easier.

Keane has been in scintillating form this season with a fourth-place finish in Mooloolaba followed up by Ireland’s first men’s World Cup podium when he took second in Ishigaki.

Fellow Irishman Conor Murphy bruised his knee in a fall in Ishigaki and was forced to return home.

This weekend’s Yokohama race is set to feature most of the top names in men’s racing with Olympic bronze medallist Jonny Brownlee making his return to racing after an ankle injury.

Last year’s winner Joao Silva is also in top form and goes into the race wearing number 1.

Alongside him on the start pontoon is Spain’s Javier Gomez and the South African bike-run specialist Richard Murray.

The women’s race gets under way on the BBC Red button or on Friday night at midnight with Aileen Reid wearing number 7 while the men’s race starts at 3am Saturday morning with Bryan Keane wearing number 27.
