All races at the 200-year-old Cholmondeley Castle start by launching into an open-water swim in Deer Park Mere Lake, transitioning on to a bike route that circumnavigates Bickerton Hill, which is the southernmost tip of the Peckforton Hills. There will be one cycle lap for the Super Sprint and two laps for both the Sprint Plus and Olympic distances.

The run passes through the estate grounds, and has one lap for the Super Sprint and two laps for the Sprint Plus and Olympic races. Triathletes will finish their Cholmondeley race experience by sprinting down the main lawn to the finish line with Cholmondeley Castle as a fitting backdrop.

The estate features extensive parkland covering 500 acres including two lakes, the larger of which, Deer Park Mere, is the setting for the open-water swim section of the triathlon.

To the south of Cholmondeley Castle, Tower Hill is the highest point of the run section, where athletes will be rewarded with panoramic views of the Beeston and Peckforton Hills, which they will have just covered on the undulating bike section, with the Welsh Hills looming in the distance.

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.

The Castle Howard Half Marathon will see competitors undertake 2 laps of a spectator friendly almost entirely off-road 10.5K circuit.

Starting on the North Lawn, a few yards from the main entrance to the castle, competitors initially head downhill towards the Boathouse and Lake before circumnavigating the enchanting woodland garden of Ray Wood. The next 5K is on a network of estate tracks and bridle paths that wind their way in a clockwise direction, always in sight of the impressive Mausoleum, passing through the ancient Bog Hall, Spring Wood, Alamo Trekking Centre and High Gaterley Farm.

At the 7K point and just after the well stocked Feed Station, competitors enter the aptly named Pretty Wood passing the Temple of the Four Faces and a couple of curious pyramids. The last 1.5K of the route builds through the formal gardens of the estate starting with New River Bridge and moving onto the South Lake, The Atlas Fountain and the South Lawn.

A final, cruel, climb to the top of Ray Wood is a precursor to a view of the Finish Line from the reservoir at the top of the hill. Lap 1 complete, runners then rejoin the same circuit for their second before entering the 500m long spectator lined finishing straight, crossing the finish line with the world famous castle backdrop, to receive their medal and classy finishing line banquet!

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.

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.
