Register Pricing Race schedule Event overview Sponsors About CLEAR ContactCLEAR Marathon Cambodia is an annual international endurance event in Siem Reap designed to generate significant unrestricted funding for APOPO Minefields to Rice Fields and agroforestry based land transition programmes in Cambodia, while delivering a direct ring fenced contribution to Siem Reap tourism development.
The event converts large scale participation into flexible capital that accelerates the transformation of cleared land into productive, climate resilient agricultural systems, strengthening rural incomes and long term stability.
CLEAR is positioned as a professionally delivered international race. It is financially viable at modest participation levels and transformational at scale.
Net unrestricted funding generated by the event supports APOPO programmes that convert cleared land into income generating agricultural systems and diversified tree based production that restores soils, improves water retention, and strengthens climate resilience.
CLEAR is designed as a high quality international race first, and a funding engine second. The professional delivery standard protects the runner experience while ensuring the event can scale.
APOPO owns the event but does not run operations day to day. Specialist providers deliver course certification, traffic control, timing, medical posture, volunteer coordination, and event production.
Physical runners, global virtual runners, and corporate teams participate under separate leaderboards and categories, creating diversified revenue streams and broader visibility.
Ten percent of net unrestricted surplus is allocated to the City of Siem Reap for tourism development and released only after the event is successfully completed.
CLEAR is built on a delivery model that reduces risk and protects reputation. Contracts, controls, and clear authority lines are set before launch and enforced by the operator team.
CLEAR uses simple controls designed to prevent financial leakage, over commitment, and reputational risk while keeping delivery agile.
CLEAR is built for runners, corporate teams, sponsors, and partners who want a premium race experience and a direct connection to measurable outcomes in Cambodia.
