La Cassya Run is a charity road event in Yverdon-les-Bains, Canton of Vaud, Switzerland, situated by Lake Neuchâtel. The primary option is an 8 km run, complemented by a 4 km walk and a 2.3 km family team event for those seeking a shorter, more social format. It typically occurs in early October, with the run commencing in the morning, the walk following shortly after, and the family event scheduled for later in the day. The organizing association, La Cassya, frames the race under a straightforward “Run For Charity” theme.
The course is an in-town road event, not a mountain or trail race, and the 8 km distance is the most frequently chosen. Entry fees are reasonable, with a slight increase for same-day registration. Funds generated support additional services for individuals affected by cancer. The event also conveys a message of prevention and awareness. La Cassya was established by Assya Gendre following her personal experience with cancer, lending the race a more personal origin compared to a typical local running event.
