We just received a notice from the Royal Parks saying that, unfortunately, water samples they collected on Wednesday 30 August 2023 afternoon came back with high levels of Blue Green Algae.
As a result, we are cancelling swimming, racing and wardening with immediate effect on 1 September 2023 until we receive "low" results - hopefully early next week.
For what it's worth, some of the species identified in the samples are known to produce toxins.
Thanks so much for your patience.
