Course from the organiser's course page. Weather: the seven days around the race date in 2023, 2024, 2025, averaged (Open-Meteo, ERA5). Sea is the sea off the town, not a reading of the swim. The water temperature that counts is the one officials measure on race morning.
Race week in three parts, the same three the Taperly app uses. Times and deadlines come from the athlete guide.
12 September 2027 to 17 September 2027
Everything that still has time to go wrong, while there is still time to fix it. Nothing you train this week makes you faster on the day, but plenty of it can make you slower.
Must do: Read the athlete guide properly, Check your race entry and category are right, Final equipment check: tyres, brakes, gears, cleats, Arrange care for kids or pets.
On site, by 18 September 2027
