The Course: Flat, But Rarely Through the Temples
The route starts and finishes in front of Angkor Wat itself and threads past Prasat Kravan, Banteay Kdei, Ta Prohm, Ta Keo, the Victory Gate, the Elephant Terrace, Bayon, the South Gate, Baksei Chamkrong and Phnom Bakheng before looping back [5]. It's billed as flat and it is — the terrain is a mix of paved sections and smooth, packed dirt roads with no real hills [6]. One catch reviewers flag: several of the marquee temples, including Angkor Wat's own outer complex, Ta Prohm and Ta Keo, are skirted rather than run through, with Angkor Thom being the one gate you actually pass under late in the race [6]. Another surprise for first-timers is that the roads aren't fully closed for the event, so by the second half runners can find themselves sharing the tarmac with tuk-tuks running tourist loops [6].
Heat and the Pre-Dawn Start
December sits inside Cambodia's cooler, drier season, but 'cooler' is relative — the race still starts around dawn specifically to get ahead of the heat, and runners report sweating heavily even before sunrise [5]. That early, low-light start means the opening stretch is run largely in darkness, which some travelling runners find atmospheric and others find disorienting given the uneven dirt sections [6]. Whatever the forecast, hydration strategy matters more here than pace strategy — this is a race where the climate, not the terrain, is the real opponent [5].
Logistics: Distances, Aid Stations and Getting There
The event offers four distances — the 21.1km half marathon plus 10km, 5km and 3km options — run under the National Olympic Committee of Cambodia with the Athletics Federation of Cambodia. On course, reviewers describe water roughly every 2km [5], handed out as 600ml bottles alongside mini bananas [6]. Transfers matter too: with an early start, arranging transport to the start area the night before is a recurring piece of advice from past finishers [6].
Scale, History and Atmosphere
This isn't a boutique event. The 2025 edition — its 30th anniversary — drew a record roughly 16,000 participants, including more than 3,000 international runners from 86 countries, a 25 percent jump on the previous year [2][3]. The race traces its roots to 1995, when it was created under UNTAC and the National Olympic Committee to draw attention to landmine survivors, and the humanitarian mission still funds a range of social programs today [2]. Cambodia's Deputy Prime Minister captured the pitch at the 2025 opening ceremony, describing runners moving past ancient trees that have lined the course for centuries in front of a UNESCO World Heritage site [3]. That combination of scale, cause and setting is what gives the event its atmosphere — big crowds, community energy, and a genuine sense of occasion rather than a quiet temple jog.
Competitiveness and Should You Run It
Don't come expecting a fast field or a personal best. In the 2025 race the men's winner finished in 1:10:26 and the women's winner in 1:33:40, times that reflect the heat and course conditions rather than a lack of ambition [3]. If you're chasing a serious time, this is the wrong race; if you want a half marathon that doubles as a once-in-a-lifetime cultural experience, complete with sunrise temple silhouettes and a genuine charitable backbone, it delivers. The 2026 edition is confirmed for Sunday 6 December, though full registration details were not yet published at the time of writing, so this is one to add to a calendar reminder now rather than a last-minute entry [4][1].
