The most recent IFSC World Cup, held in Chinese city Nanjing last weekend, combined the bouldering and speed disciplines.

Japan’s Keita Watabe and Great Britain’s Shauna Coxsey won the respective men’s and women’s bouldering events in the Chinese city.

Sport climbing was added to the Tokyo 2020 Olympic programme in August of last year along with four other sports.

Completing the line-up of new additions is baseball/softball, karate, skateboarding and surfing.
