Chateau de Chantilly Water Test
We have received our latest water test, from a sample taken on Monday 19th August. This sample was taken from the Grand Canal following two days of heavy rain on the 17th and 18th August.
The water sample consists of two microbiological tests, and one of these tests falls outside the recommended safety parameters expected for open water swimming.
This is to be expected after two days of heavy rain. However, due to the fact that there has been no further rainfall, plenty of direct sunshine, which serves to dissipate microbes in stretches of open water, combined with a good flow rate of fresh water in the stream-fed Grand Canal, we are confident that we are safe to proceed with the swim this weekend. We have managed open water swims at triathlon events for over ten years, and have a good understanding of the microbiology of lakes.
This result is an anomaly in ten years of water testing at Chantilly and due to the rainfall on the 17th and 18th August. We are retesting the water, and we will have the test results on Monday 26th August.
Having sought advice from the ARS, the water safety authority, and the French Triathlon Federation, the swimming elements of our event this weekend will proceed as normal, but, it is ultimately the choice of the athlete if you would like to take part in the swim. If you do not wish to swim this weekend, your options are to:
- Take part in the cycle and run legs of your triathlon only.
- Transfer your race to one of our Sprint (Saturday) or Standard (Sunday) Duathlon races, or one of our 10k, Half Marathon or Marathon races.
If you wish to amend your race entry, please do this by speaking to the Help Desk in the Registration Tent at Chateau de Chantilly.
- There will not be a swim for any junior race (8-15 years old). All junior races will become a competitive duathlon, where all three races will begin with a 600m run.
Further information will be provided at Registration and during the briefing.
