Over 500 swimmers swam in the near-freezing waters of Tallinn port in Estonia, taking part in a giant winter swimming relay in a country where the sport has been a popular way to counter the tedium of coronavirus restrictions.

The 505 participants each swam the course of 25 metres marked out in a former submarine dockyard, taking 4 hours and 50 minutes to do so.

The swimmers, many attired with funny hats, ranged from a nine-year old boy to an 83-year old woman, and included a pregnant woman who joked her effort should be counted for two.
