BMX star Shanaze Reade says the World Championships are going to be nerve-wracking but will help her prepare for the Olympic Games.
Shanaze is the UK's best female BMX rider and has lots of world titles under her belt.
She's looking forward to the Olympics this summer, but before that she's got the BMX World Championships in just over a month to test how she's going.
Shanaze is training really hard - two times a day, six days a week.
Hayley's been to meet Shanaze. Watch her report and find out what happened when she challenged the BMX star to a race!
