5,000 runners braved the heat in the central beach town of Quy Nhon on Sunday to join the VnExpress Marathon. 

Half an hour before race time, the athletes gather at Nguyen Tat Thanh Square on the coastal Xuan Dieu Street to warm up.

Besides regular marathoners who are all too familiar with the grueling nature of the race, the VnExpress Marathon also attracts a large number of entrepreneurs, beauty queens, models, children, and people with disabilities.

It is in fact a festival that brings together 120 running clubs from around Vietnam such as SRC (with 310 registered members), SolarBK, Danang Runners, HCR, VP Iron, VietRunners, RFF, Phu Tho Runners, Phu My Hung Runners, and Vietrace365.

At 4 a.m. the starter’s gun set nearly 700 runners off for the most challenging distance of 42 km. Most of them are semi-professionals or those who have spent a lot of time training for the marathon.

5,000 people joined the VnExpress Marathon 2019, organized by VnExpress and the Binh Dinh Province People's Committee, including 115 foreigners from 26 countries and territories.

It’s the only marathon in Vietnam that sets the course through the Thi Nai (2.5 kilometers) sea overpass.

Organizers will donate 10 percent of the ticket sales proceeds to VnExpress’ Hope Foundation, which works to improve learning facilities for disadvantaged students.
