One of Bhutan's largest running events gives international entrants a rare chance to race through the Paro Valley alongside local runners. International entry is sold with travel packages, while those fees help fund free places and prizes for Bhutanese athletes.

Course

The marathon runs through the Paro Valley amid mountain scenery, passing Paro Dzong and Buddhist chortens along the way. Elevation and valley terrain make this a mountain effort even where the route is runnable, so acclimatization matters.

Race-day weather

May in Paro can bring a cool high-altitude morning, strong sun, and a noticeable temperature rise in exposed valley sections. Thin air increases effort, while mountain weather can shift quickly enough to justify layers.
