100km voor Kom op tegen Kanker (KOTK)

The 100km voor Kom op tegen Kanker is a 100-kilometre team running event in Belgium, focused on fundraising for cancer research. The name connects it directly to Kom op tegen Kanker, a Belgian campaign against cancer, making the race as much a charity effort as a long-distance running challenge.

Those runners raised a record 3,396,250 euros for cancer research, making the fundraising total the standout fact.
