It remains a favourite for runners chasing Boston qualifying times.

Lanzhou Marathon

The Lanzhou Marathon is one of China's largest road races, drawing approximately 40k finishers along the Yellow River through Gansu's highland capital. Runners follow the riverside promenade past the Zhongshan Bridge, White Pagoda Mountain, and the iron bridge that symbolises Lanzhou's Silk Road heritage. The June race date and roughly 1,500 m elevation make it a distinctive western-China marathon where thin air and Yellow River views define the experience.
