About Madswimmer

What started off as a late winter night’s bet in a chalet on French mountain slopes in 2009 celebrated a successful ending six years later.

Since inception Madswimmer has raised in excess of $300 000 for 11 children’s charities. One of the Madswimmers, Hardi Wilkins, commented after a challenging swim, “we did it and it was no small feat! Facing radical weather, training and fund raising, it is all worth it in the end.”

Madswimmer Tanganyika Swim

Swim for Nsumbu is an open water swimming event on Lake Tanganyika created to bring attention to the challenges facing Lake Tanganyika caused by overfishing, climate change, poaching and general environmental degradation.

The November 2014 swim was a collaboration between Madswimmer and CLT (Conservation Lake Tanganyika). The decision was made to attempt the first ever trans Tanganyika open water swim, swimming in one day across lake Tanganyika from Tanzania in the east to Zambia in the west. The focus was to raise awareness and funds for CLTs work in and around Nsumbu National Park.

The total distance covered by swimmers was 38.5 kms. Madswimmer Jean Craven was the only one to complete the entire distance nonstop! The total swimming time was 12 hours. Madswimmer relay swimmers were: Megan Harrington-Johnson, Michiel le Roux, Milton Brest, Gary Isbister, Jessica Comana, Elaine Sinden, Linda Main, Robert Dunford, Shaun Davy, Marcel du Toit and Marius de la Rey.
