Course & Elevation
The Vientiane International Half Marathon is a half marathon in the Lao capital, held on a Sunday in early March, with a 10 km race on the same morning. It starts very early, at 4:30 am in 2026, to avoid the heat, and the start and finish are at That Luang Ground. The organiser, EFG Laos (Events for Good), describes a flat course through the city that passes landmarks, quiet neighbourhoods and wide boulevards. The first edition was held at That Luang Square on 6 March 2016 as a fundraiser for girls' sports, with a 21 km half marathon, a 10.5 km quarter marathon and a 5 km fun run. The 2016 half marathon ran from That Luang Square to the Patuxay monument, past the Mercure Hotel to Wattay International Airport and back along the Mekong road. The Lao Athletics Federation has co-organised the event with Events for Good. AIMS lists the next edition for 7 March 2027.
