Twenty athletes are due to take part in the latest Ready Steady Tokyo test for the Olympics tomorrow, this time in skateboarding.
The sport is set to make an Olympic debut at Tokyo 2020.
Originally scheduled for April 28 and 29, the test event is due to run for two days at the Ariake Urban Sports Park on the shores of Tokyo Bay.
The main event will be held at the same venue from July 25 to August 5, and will comprise men's and women's competition in the park and street disciplines.
The Tokyo 2020 skateboarding courses are a culmination of the designs and experiences derived from a number of World Championships and qualifying events.
Each course will be considerably larger than is typical but still small enough to allow athletes to take advantage of all obstacles during a run.
Both the street and park courses have been designed with equality in mind - both in terms of gender and athletes' stance.
Street competition is held on a straight, street-like course featuring stairs, handrails, curbs, benches, walls and slopes.
Each skateboarder performs individually and uses each section to demonstrate a range of skills.
Judging takes into account factors such as the degree of difficulty of the tricks, height, speed, originality, execution and the composition of moves, in order to award an overall mark.
Park competitions take place on a hollowed-out course featuring a series of complicated curves - some dome-shaped bowls, and athletes can achieve considerable heights to perform mid-air tricks.
Qualification for the Olympics is based on global rankings maintained by World Skate, the sport’s global governing body.
