Important information for participants: Cancellation of the Swim. This year, due to the heat wave, the canal of the Château de Chantilly is also suffering and does not have enough water depth for swimming. In consultation with the Domaine de Chantilly and the Sub-prefecture, access will not be allowed and the swimming events will be cancelled. All triathlon entries have been automatically converted to the equivalent duathlon distance in accordance with FFTri recommendations.

The Castle Triathlon Series makes its yearly pilgrimage over the English Channel in August for the 2022 series. Set over the UK bank holiday weekend at the end of August, the event takes place in the spectacular and historic town of Chantilly, just a 2.5hrs drive from Calais and 40 miles north of Paris.

The Castle Swim will provide swimmers with the exclusive chance to take on one of the three distances - 5k, 2.5k and 1mile - in The Grand Canal in front of the Chateau.
