Open water race collections

Hand-picked lists from across the calendar: races grouped by what sets them apart — history, distance, place.

The monuments of open water swimming

Open water swimming has its monument races: sea, lake and river swims that towns and clubs have organised for generations. This page gathers the oldest events on our calendar: every race here held its first edition by 1975, the oldest are past their hundredth year, and all of them are still being swum. They are ordered by year of birth, oldest first, with the date of the next edition, the distances on the programme and a line of history for each — who founded them, which waters they cross, what stopped them for years and what brought them back.
