Ultra-Trail d’Angkor: Siem Reap Runner’s Guide

Ultra-Trail d’Angkor is an endurance-running event based around Siem Reap and the Angkor landscape. The programme typically offers several trail distances, allowing experienced ultra-runners and shorter-distance participants to explore forest paths, rural communities and heritage scenery.

Choosing a race distance

Distances, qualification rules, cut-off times and mandatory equipment vary by edition. Select a category based on recent training and trail experience, then read the current regulations in full. Long courses require careful preparation for heat, darkness, uneven ground and extended time between aid stations.

Running responsibly near Angkor

The event passes through a living cultural landscape. Stay on marked routes, respect residents, avoid restricted temple areas and carry out waste. Follow race officials and heritage-authority instructions even when they differ from an old course map.

Training and equipment

• Build distance gradually and practise on trails.
• Test hydration, nutrition, shoes and lighting before race week.
• Train for warm, humid conditions.
• Carry every item on the current mandatory-equipment list.
• Arrange insurance suitable for endurance sport and Cambodia.

Siem Reap travel planning
