Castle Triathlon Series

Formed in 2009, the Castle Triathlon Series has swiftly established itself as the UKs largest triathlon series.

From Lough Cutra to Chantilly and Castles Howard, Cholmondeley and Hever, were immensely proud of the iconic backdrops to each Castle Triathlon Series race and the friendly festival atmosphere produced at every event.

The rapturous reception afforded to previous Castle Howard Triathlons subsequently led to the expansion of a 2-day weekend extravaganza.

In its 9th year, the Castle Howard Triathlon will be the 4th weekend event of the 2018 Castle Tri Series and will once again feature the obligatory picture postcard backdrop and a course with something for every level of triathlete. The 13,000 acre grounds of Castle Howard form arguably the most physically demanding triathlon course of the Castle Tri Series.

Race entrants will start the race by swimming through Castle Howards Great Lake before transitioning into the technical bike route through the glorious rural idyll of Yorkshire and the Howardian Hills. The spectacular run leg passes through the undulating countryside of the estate before a sprint finish tops everything off in style right in front of the main doors of the house. Theres never been a better time to visit Gods Own County and Castle Howard.

The construction of Castle Howard took more than 100 years before being finally completed in the 18th Century, and spanned the lifetime of three earls and numerous architects, although Sir John Vanbrugh is credited with the original design. The Great Lake is the setting for the swim section of the triathlon.

Set in the Howardian Hills, the bike legs initially take in the 18th Century Avenue, a main road that runs in a straight line from south to north for five miles. The run will pass The Temple of the Four Winds and one of the finest, free-standing mausoleums in Europe. A hop over New River Bridge, a circumnavigation of South Lake and the Atlas Fountain will take racers to the finishing straight in front of Castle Howard itself.

Castle Howard has been a regular backdrop for films and television, with both ITVs lauded Brideshead Revisited in the early 1980s and the acclaimed 2008 feature film production shot on location here, hence the name of our adult races.

Set over the UK bank holiday weekend, the racing will take place in the spectacular and historic town of Chantilly, just a 2.5hrs drive from Calais and 40 miles north of Paris.

Over 3200 participants took part in the hugely successful 2016 event. As we look forward to 2017, the event will continue to include a whole spectrum of distances, with races for children aged eight and up to the middle-distance race, Le Gantelet, first introduced at Chteau de Chantilly in 2013.

Chantilly provides a fantastic and challenging race, with the 2.5km Grand Canal overlooked by the Chteau and its gardens hosting the open-water swim. Triathletes will transition within the Terrasse des Conntables and set off into a fast 20km or 45km cycle circuit around the Fort de Chantilly. After entering T2, competitors will run the surrounding woodlands, the world famous race course LHippodrome and Chateau gardens finishing within sight of the beautiful Chateau.

Hever Castle Triathlon has established itself as an essential destination for British and international triathletes and the mainstream media, for its picture postcard venue, elite action, age-group choice and festival atmosphere. Put simply, instant classic doesnt do the Hever Castle Triathlon justice.

The races commence with an open-water swim in the spectacular 38 acre Hever Castle Lake and River Eden, transitioning into the undulating cycle that takes athletes around a circuit through the High Weald of Kent, an Area of Outstanding Natural Beauty, and up to the stunning Ashdown forest for the longer distance races. The largely off-road run circumnavigates the estate and award-winning castle grounds before athletes make the dash to the tree-lined finishing chute beside the lake.
