    Château de Chantilly

    Saturday 29th and Sunday 30th August 2020 - CANCELLED


    14 August 2020

    In the last 24 hours, much has changed with regards to travel between the UK and France. The English government has enforced a 14-day isolation period and the French government is planning to reciprocate in the next few days and, at the moment is permitting entry to France for essential travel only.

    Despite our very best efforts to go ahead, this has left us with no option but to cancel the Château de Chantilly event on Saturday 29th and Sunday 30th August 2020. This difficult decision has been made in consultation with our French partners, suppliers, the Château and with the Sous Préfecture (local safety advisory group) in Chantilly. There is, of course, a lot of pressure from the French government to keep regions across France as safe as possible and Covid-19 cases to a minimum, and so the Sous Préfecture has requested the event no longer goes ahead.

    The enforced isolation on arrival and departure from France dramatically affects the travel plans of all our staff and suppliers. This means it is not possible for us to run a safe event at this time.

    We are hugely disappointed about this decision, and appreciate that this will come as a big blow to you too. We are grateful for your ongoing support and understanding in these times of rapidly changing circumstances.

    We have opened up options for transferring your race place so please use this button to find out more.

    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.

    A Socially Distanced Event

    We want to reassure all participants that we’re working with governments, governing bodies, venues and suppliers to ensure that our 2020 events are run in accordance with current health and safety guidance.

    Our increased health and safety measures cover 4 key principles of education; touch point reduction, density reduction, athlete self-reliance and enhanced hygiene.

    Participants will still get the full race experience but with 5 people in a rolling start, restricted time on site either side of your race and 1 spectator per athlete only.

    We are preparing venue specific documents which we will share here shortly and send to all participants ahead of the event, which will include details on how to prepare pre-event, arrival timings and movements, swim, cycle, run, festival village and exit.

    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.

    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.
