Château de Chantilly Triathlon

Saturday 29th and Sunday 30th August 2020

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.

As we look forward to 2020 as this event continues to grow and  include a whole spectrum of distances, with races for children aged eight and up to the middle-distance race, Le Gantelet, first introduced at Château de Chantilly in 2013.

Chantilly provides a fantastic and challenging race, with the 2.5km Grand Canal overlooked by the Château and its gardens hosting the open-water swim. Triathletes will transition within the Terrasse des Connétables and set off into a fast 20km or 45km cycle circuit around the Forêt 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.

Chantilly - Présentation

About Château de Chantilly

Chantilly cream, one of Europe’s finest art collections and a Bond villain’s hideout. The Château de Chantilly has a long and varied history that began in the mid-14th Century.

Construction of the estate is thought to have begun in 1358, with the Grand Château razed during the French Revolution of the 1790s before being rebuilt in the 1870s.

The stretch of water that plays host to the swim section of the triathlon is the Grand Canal, a 2.5km long tributary of the Oise. The cycle route circumnavigates the arrow straight bridleways of the Foret de Chantilly, with the run section named after the Maison de Sylvie that it surrounds.

Owned by the Institut de France, the château houses the Musée Condé, which is one of the finest art galleries in France and is open to the public. It was also at the Château de Chantilly that a French chef, François Vatel, invented Chantilly cream in 1671.

Château de Chantilly also has a rich history in popular culture. James Bond fans will note that it acted as the estate of Christopher Walken’s villain, Zorin, in A View to a Kill from 1985, while more recently it was used as a location for 2006’s Pink Panther remake, which lends its name to our children’s races. Pink Floyd played two concerts here in 1994 and Ronaldo (the Brazilian one) used the Château to host his 2005 wedding.

Enter Le Gantelet

For the ninth year running, the middle-distance Le Gantelet will be held at the Château de Chantilly Triathlon. In 2020 the race will be hosted on Sunday 30th August, and will consist of a 1.9km swim, 90km cycle and a 21km run.

Le Gantelet is perfect for those who wish to upgrade from sprint and Olympic-distance racing or simply want to take on a new triathlon challenge. The stunning venue and scenic grounds set the scene for a motivating event that will nurture your most extreme triathlon ambitions.

Castle Swim Series

Saturday 29th August 2020

The swim only event provides the choice of three different distances: 5km 2.5km and 1mile (see price table below) and boasts a unique and stunning swim route in all the stunning castle lakes.

The swim described by many triathletes as the ‘best open water swim ever completed’ will now be open to outdoor swimmers as an event in its own right.

All swimmers will be provided with timing chips and the races categorised into wetsuits and non-wetsuits. Prizes will be awarded for the top three male and female competitors in each distance.

One mile leisure and family swim

Enjoy the beautiful setting of the Chateau de Chantilly at your own pace. Swim any stroke you like (breaststroke encouraged), swim and chat with friends as you go around. Don’t worry about how long it takes (however time limit set at 90 minutes), just enjoy it. Under 16s welcome if accompanied throughout by a competent responsible adult.

10K, Half Marathon & NEW Marathon

Sunday 30th August 2020

Building on the success of the Castle Run Series introduction in 2018, the 10K, Half Marathon and Marathon will be returning to the iconic Chateau De Chantilly. As the venue lends itself so well to running, we are excited to introduce the NEW FULL MARATHON to our run routes at the Chateau.

This stunning and unique multi-terrain course will incorporate spectator friendly loops of the French countryside, the Castle lake, and of course the Chateau itself. Each runner will receive a medal and will be welcomed across the finish line with a banquet of well-earned treats, with live bands, food stalls and a retail area, making the weekend a festival of sporting achievements.
