Truphena Muthoni is a Kenyan environmental conservationist, climate, sustainability and mental health advocate.^[1] She is a Guinness World Record holder for the longest marathon hugging a tree for 48 hours in Michuki Memorial park in Nairobi between January 31 and February 2, 2025.^[2][3] The record-breaking moment was witnessed by Kenya’s Permanent Representative to the United Nations Environment Programme, Ababu Namwamba, among supporters, friends and relatives.^[4] On 12 December 2025, Muthoni challenged her previous record by the 72hour tree hugging marathon in Nyeri at the governor's office compound, enduring hunger, fatigue, and very harsh weather.^[5][6] Muthoni is a defender of forests, indigenous trees, people and animals. The tree hugging is a form of peaceful protest to urge leaders to respond to pertinent environmental issues

Muthoni was scheduled to attend the 2025 United Nations Climate Change Conference (COP 30) in Brazil from 10-21November 2025 on climate action and the struggles of indigenous peoples, but did not get the required accreditation, badge, and funding from the Ministry of Environment, Climate change, and Forestry. The setback inspired her to continue with the 72-hour tree hugging in Kenya.^[5][7]

Muthoni says that hugging trees is therapeutic and can bring happiness and relief for those struggling with mental health especially because mental health issues and climate injustices are linked to environmental degradation. Victims of climate change and those affected by wildfires, floods, and drought experience post-traumatic stress and reconnecting with nature can bring healing. She is a defender of indigenous trees and advocates that people love nature, treat it with care, and plant indigenous trees as mitigation rather than replacing them with saplings.

Muthonis' clothing and style is symbolic. She had 17 strands of braided hair made from recycled yarn strands, representing the 17 Sustainable Development Goals. The braids had four distinct colours; Black symbolizing African power, protest and resilience; Green for regeneration, reforestation, and hope; Red for Indigenous resistance and frontline courage; and Blue for honouring water protectors and ocean defenders.^[5] Muthoni wore a blindfold for several hours during the 72-hour marathon to raise awareness about those living with disabilities, and their vulnerability to the effects of climate change.^[8] Her efforts are focused on raising awareness about nature’s healing potential, particularly in addressing the growing prevalence of climate-related post-traumatic stress disorders. Muthoni believes in the restorative power of nature and stresses the critical importance of preserving it for future generations.^[1]

Truphena Muthoni was born and raised in Mathira Sub-county in Nyeri county, Kenya. She attended Parklands Baptist primary school and Narumouru Girls High School. She was an active scout rover.^[4] At the 2025 Founders Day Celebration in Nyeri, Muthoni credited her Scouting background for instilling in her the values of perseverance, leadership, and a deep sense of responsibility toward creating a sustainable world. She reflected on how Scouting camps and programs have moulded her character, teaching her the importance of taking action for a better planet.
