Oloolua Forest Needs You Right Now
Oloolua Forest is 618 hectares of indigenous forest in Karen, one of Nairobi's last natural forests. It sustains water, biodiversity, and livelihoods for over 4 million people. Yet 25 kilometres of its perimeter remain unprotected.
The Run for Oloolua is our solution. Every race ticket funds 9 metres of protective fencing. 2,800 runners collectively fund the entire perimeter. The race is part conservation mission, part community movement, and part festival.
