The Tour de 4 is an initiative launched by Sir Chris Hoy to challenge perceptions of people living with stage 4 cancer and to raise vital funds for cancer charities across the UK.

The Tour de 4 kicks off with the first Zwift ride of 2026 taking place on 18 April, with additional rides leading up to the Tour de 4 in-person event in September. Zwift is encouraging as many people as possible to take part in the rides and donate to the cancer charities that mean the most to them. Zwift will also be donating £50,000 to the Tour de 4 charities.

All funds raised will be collected as part of Sir Chris Hoy’s Tour de 4 project and distributed among five leading cancer charities chosen by Sir Chris: Breast Cancer Now, Macmillan Cancer Support, Maggie’s, Cure Leukemia, and Prostate Cancer UK.
