About these races

Chengdu Marathon

The Chengdu Marathon draws approximately 35k runners each autumn through Sichuan's relaxed capital, famous for pandas, hot pot, and teahouse culture. The course passes Tianfu Square, the Jinjiang River, and the Anshun Bridge with views toward the Qionglai mountains on clear days. October race weather in the Sichuan Basin is mild and overcast — ideal for a flat, fast urban loop.

London Marathon

The TCS London Marathon is one of the world's most popular races, famous for its incredible charity fundraising and electric atmosphere. The fast course passes Tower Bridge, the Cutty Sark, Canary Wharf, and finishes on The Mall in front of Buckingham Palace. With gentle undulations and around 127 metres of total climbing, it consistently produces fast times — including Sabastian Sawe's 1:59:30 men's world record and Tigst Assefa's 2:15:41 women's-only world record, both set at the 2026 race.
