01 The Event

What Is the Classic Day Tours

The Classic Day Tours is an annual event that celebrates the September equinox with a race through the Angkor Archaeological Park. It is organized in cooperation with the park authorities and is open to both local and international runners. The run starts in the early morning, before sunrise, to take advantage of cooler temperatures and to allow participants to experience the sunrise from within the park boundaries.

The event is not a competitive marathon. It is a participatory run, with chip timing provided for those who want it. The atmosphere is informal, and the focus is on the experience of moving through a historic landscape at dawn. Multiple distances accommodate different levels of runners, from a short fun run to a half-marathon, so the event remains accessible whether you are a regular runner or simply want to be part of the equinox morning.

Organized With

Angkor Archaeological Park authorities, with permits for road closures during the event window.

Open To

Local and international runners, all ages and abilities. A wheelchair category is offered for the 3K and 10K.

Focus

Participation over speed. Chip timing is available, but the event centers on the dawn experience.

03 — The Route

Through the Angkor Park

The route passes through the Angkor Archaeological Park, one of the most significant archaeological sites in Southeast Asia. The 10K and half-marathon routes start near Angkor Wat and proceed north through the park, passing the walls of Angkor Thom, the Bayon temple, and the Terrace of the Elephants. The course is on paved roads, which are closed to traffic during the event.

The roads are wide and mostly flat, with some gentle inclines near the temple entrances. The route is marshaled by volunteers, and water stations are set up at regular intervals. The half-marathon extends beyond the main park area, through local villages and rice paddies, offering a broader view of the Cambodian countryside.

04 — Registration

Registration and Entry Fees

Registration is available online through the event's official website or through authorized registration partners. Early registration, which usually opens several months before the event, offers a discounted entry fee. The fee varies by distance, with the 3K being the least expensive and the half-marathon the most.

Registration is also available on-site during packet pickup, but the fee is higher, and the availability of t-shirts and medals may be limited. To participate, you will need to provide your name, age, gender, and emergency contact information, and sign a waiver.

Entry Fee Includes
  • + Timing chip for official results
  • + Finisher's medal
  • + Event t-shirt
  • + Contribution to local charitable causes, often focused on children's education or health in the Siem Reap area
Note: The entry fee does not include the Angkor Archaeological Park pass, which is required for the 10K and half-marathon distances.
Packet Pickup and Pre-Event Logistics

Packet pickup takes place the day before the event at a designated location in Siem Reap, often a hotel or conference center. At pickup, you receive your race number, timing chip, t-shirt, and event materials. This is the time to ask questions about the route, start time, and transport to the start line.

The pickup location is usually open for a few hours in the afternoon and evening. If you cannot attend, someone else can collect your packet with a copy of your registration confirmation and ID.

05 — The Sunrise

Running the Equinox Sunrise

For participants in the longer distances, the start of the run often coincides with the equinox sunrise. The half-marathon typically starts at 5:30 AM, which means that runners are on the course as the sun rises over the temples.

Running through the park as the sun rises behind the central tower of Angkor Wat is a distinctive experience, and it is a different way to witness the equinox alignment. The route passes the western causeway of Angkor Wat, and runners get a view of the sunrise as they run past.

The 3K fun run starts after the longer distances, usually around 6:30 AM, and is over by 7:00 AM. If you are participating in the run, you can still experience the equinox sunrise, but your viewing position will be on the course, not standing at the causeway.

06 — Preparation

Training and Preparation

The Classic Day Tours takes place in September, during the green season in Cambodia. Early morning temperatures are relatively cool, around 24 to 26 degrees Celsius, but humidity is high. If you are traveling from a cooler climate, allow a few days to acclimatize before the run. The course is flat, which makes it fast, but heat and humidity can still be a factor. Hydration matters — drink water at every station.

3K Basic Fitness

No specific training is needed beyond the ability to walk or jog for 20–30 minutes. The course is flat and does not enter the main temple complex.

~20 min
10K One Hour Comfort

You should be able to run for about an hour comfortably. The course passes through the park on paved roads, with some gentle inclines near temple entrances.

~60 min
21K Training Base

A training base of at least 30 to 40 kilometers per week for the preceding two months. The half-marathon covers Angkor Wat, Angkor Thom, and extends through villages and rice paddies.

30–40 km/week
What to Wear and Bring
  • · Light, breathable clothing suited to high humidity
  • · A hat or visor for sun protection as the morning brightens
  • · Angkor Archaeological Park pass for the 10K and half-marathon
  • · Emergency contact information and signed waiver from registration
On Course
  • · Water stations at regular intervals along all routes
  • · Volunteer marshals directing runners at turns and intersections
  • · Roads closed to traffic for the duration of the event
  • · Chip timing — the focus is on participation, not speed
07 — Combining Both

The Run and the Sunrise

If you are participating in the run and also want to view the equinox sunrise from the western causeway, you can do both, but it requires planning. The half-marathon starts at 5:30 AM, before the sunrise at 5:53 AM. If you are running the half-marathon, you will be on the course during the sunrise and will see the alignment from the route.

After the run, you can return to Angkor Wat for a closer view, but the crowd will have dispersed by then. If you are running the 10K, which starts at 6:00 AM, you can view the sunrise from the causeway before the run — you will need to be in position by 5:30 AM and then walk to the start line. This is feasible if the start line is near Angkor Wat.

Alternative

You can also choose to run on one day and view the sunrise on another day during the equinox window. The solar alignment is visible for a few days around September 21, so splitting the experiences is a practical option.
