In 2021, Olympic marathon champion Eliud Kipchoge adopted 50.8 hectares of Kenya's Kaptagat Forest for rehabilitation. 5 years later, more than 1,277 hectares of the wider ecosystem had been rehabilitated. The work is part of a programme that began in 2017 after large sections of the forest were identified as degraded because of human activity. The target is to restore 2,000 hectares across five forest blocks. Government agencies, community groups, conservation organisations and other partners are involved. Kipchoge has also linked the protection of the forest to the environment and the high-altitude areas used by Kenyan athletes for training.
