Castle Howard Triathlon
Castle Howard, Yorkshire and the Humber, United Kingdom

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

In its 10th year, the Castle Howard Triathlon will be the 4th weekend event of the 2019 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.

NB All timings are approximate.

£35 - £220

The Wasdale Triathlon Half X
Seascale, North West, United Kingdom

Described as the deepest, steepest and the highest, this half Ironman challenge is surely one of the toughest in the Country. The swim is in Wastwater, the Lake District's deepest; the bike leg has 7,217ft of climb over the big three Lakeland passes - Kirkstone via the 'Struggle', Wrynose and Hardnott, both directions - and is described as the steepest and most gruelling half Iron Bike section anywhere in the World; the run around the stunning Fairfield Horseshoe ascends over 2,600ft. But it's not so much the total ascent that will hurt, it's the severity that will cause the damage! (Date tbc)
