The first Snowboard World Cup big air event since the discipline was included in the 2018 Winter Olympics will take place in London on 14 November.
Big air involves competitors performing a trick off a large jump.
Britain's Jamie Nicholls will be among 60 of the world's best male and female snowboarders and skiers competing.
The event will be held at London's Queen Elizabeth Olympic Park "on a huge real snow jump measuring 120 metres x 41 metres", say organisers.
"Billy Morgan and Katie Ormerod are real medal prospects in 2018," said British snowboarder Jenny Jones, a 2014 Olympic bronze medallist and event ambassador.
"And the fact that we'll be able to see the best riders in the world battling it out in the middle of London will be an amazing start to each winter."
