The IDERHA 5000 challenge

IDERHA project members are are collectively accumulating kilometers through activities such as walking, running, cycling, and swimming. Our goal is to collectively cover a distance of 5000km and collect 5000 euros for KWF, the Dutch Cancer Society, in two months (October-November 2026).

On this page we will collect donations for this challenge and frequently update the distance we have covered so far.
