This first race sets the scene for a competitive and fun series, hosted within the beautiful grounds and surrounding area of stunning South Galway. What’s more, the race coincides with a Bank Holiday in the UK and it is also the first weekend of the UK school half term, making it an ideal break for sporty families.

All of the races at Lough Cutra Castle kick-off by launching into an open-water swim in the lake, transitioning into a bike route which circumnavigates Lough Cutra itself. The half iron gauntlet cycle takes in the beautiful Burren national park.

Lough Cutra Castle Triathlon

About Lough Cutra Castle

The countryside surrounding Lough Cutra contains evidence of a history dating back to the Irish-Celtic mythology of the Tuatha Dé Danaan.

Old churches, cells and monasteries are prolific in the area, with some of the islands on the lake containing the remnants of stone altars.

The history of the actual estate can be traced back as far as 866 A.D. when the ruined church of Beagh was sacked by the Danes and war raged through the district for nearly 1,000 years.

The Castle itself was built during the Gothic revival period and is idyllically situated overlooking the Estate’s 1,000 acre lake (the largest privately owned lake in Europe), home to the open-water swim of the Lough Cutra Castle Triathlon.

2017 Sprint Super Series

Triathlon Ireland has awarded Lough Cutra Castle Triathlon the Sprint Super Series on Saturday 27th May 2017.

It’s going to be a Super Saturday at this year’s Lough Cutra Castle Triathlon on May 27th with Ireland’s Cat 1 and Cat 2 top age groupers battle it out in the first event of the 2017 Sprint Super Series, the only one in the West of Ireland.

The Super Series, now in its 3rd year in Ireland, caters for the appetite, skill and speed of the fastest athletes over the sprint distance triathlon of 750m swim, 20km bike and 5km. Racing on closed roads in a draft legal environment, chasing points, it’s the only series in the country that allows this type of triathlon racing.

New in 2017, Cat 2 athletes will be racing alongside Cat 1 and in addition Cat 2 will be eligible to score points in the Triathlon Ireland National Series while competing in this Super Series. Full details here.

For the first time this year, Triathlon Ireland will be awarding separate Cat 1 and Cat 2 cash prizes to the top men and top women for the overall standings at the conclusion of Super Series. Those wishing to register for the draft legal Super Sprint Series can log in HERE.

Not only will the super speedy athletes race at this distance for the first time in Lough Cutra, we have also added a non draft legal sprint race to our racing schedule to cater for the demands of those wishing to race at the sprint distance.

Mixed Team Relay - New race in 2017!

This new race format, taking place on the afternoon of Saturday 27th May, will see four person teams; two males and two females, each completing a 250m swim, 5km bike and 1.5km run as part of a tag team.

Mixed Relay has proven extremely popular with athletes of all standards and allows regular age groupers and more advanced athletes to race together. The minimum age requirement for athletes is 15 years. There is no upper limit upper age limit or ability for those taking part.

Participants who are racing any other distance over the weekend can get a 50% discount on the full price of the Mixed Team Relay entry.  Email us here to apply.

We are delighted that this event will include the National Mixed Team Relay Club Championships. The race will be run to ITU standards and all participants must hold a full TI Licence and team members must belong to the same club.

Go long for the Gauntlet

In 2017 Lough Cutra, for the fourth year running will see The Gauntlet, a middle-distance race, push competitors to their limit via stunning 1.9km swim, 96km bike ride and 21km run.

This race distance had a hugely successful launch across the Series in 2014 with over 1000 sign ups. Since then it has gone from strength to iron strength doubling in size with hardened triathletes and newcomers to the triathlon side-by-side on the start line. In 2016 we were proud to host the Gauntlet as part of the Triathlon Ireland Vodafone National Series.

In 2017 The Gauntlet at Lough Cutra will offer 5 qualifying places in each Age Group for the 2018 ETU European Middle Distance Championships. See more about Event Qualification.

Stunning scenery & weather for a swim, cycle & run around the estate of Lough Cutra Castle in Co. Galway, Ireland. Well organised & great inspiration from both half ironman distance triathletes and also young kids doing their own triathlon race!
