Castle Howard Triathlon

Saturday 22nd and Sunday 23rd July 2017

2017 British Triathlon Age-Group Qualifier

In 2017 Castle Howard’s Olympic (Standard) distance has been awarded with 2018 ETU Standard Distance Triathlon Qualifier status.

In 2016, the amount of Great Britain Age-Group Team entries to ITU World Championships and ETU European Championships grew by 15% from the previous year, showing the ever-growing popularity of representing your nation within triathlon. This is expected to continue in 2017, where another group of high-quality events for aspirant team members are on offer in order earn the right to wear the Great Britain Age-Group Team tri suit.

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

In its eighth year, the Castle Howard Triathlon will be the fourth weekend event of the 2017 Castle Tri Series and will once again feature the obligatory picture postcard backdrop and a course with something for every level of triathlete. Indeed, 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 Howard’s 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

About Castle Howard

With Yorkshire being voted the third best region for travel in 2014 by Lonely Planet magazine (being edged by Australia and India), there’s never been a better time to visit God’s 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 (which is actually a stately home), has been a regular backdrop for films and television, with both ITV’s 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. The film industry also visited Castle Howard for 2006’s Garfield 2: The Prince and the Paw-per, the sequel to Garfield: The Movie and the name of our junior and children’s races.

Welcome to Yorkshire

Go long for the Gauntlet

In 2017 the Castle Howard event will witness the exciting return of The Gauntlet, a middle-distance race that pushed competitors to their limit via a 1.9km swim, 90km bike ride and 21km run.

Thank you very much for the work you put in at Castle Howard. It was a fantastic event and I really enjoyed the location as much as the triathlon. Another wonderful weekend. We are looking forward to joining you in France, hopefully the weather will continue!
