The opening ceremony on Wednesday evening in Saalfelden.
With a strong Richie Rude in the Junior category and Aaron Gwin in the Elites, the US team has fair chance to take home both of those titles this weekend.
All season in the World Cup overall, we've witnessed an intense battle between Emmeline Ragot and Rachel Atherton, this time though, only one run counts and Ragot could go for her third title.
Before the amazing mountain scenery here in Leogang gets covered in clouds for the next few days you have to take your chances. Gee Atherton.
Seven times Greg Minnaar has finished in the top three at the past ten World Championships but only won it once. You can be sure he'll be hungry to win a second title.
Michal Prokop is looking to defend his Rainbow jersey from Champery.
The pressure is on Aaron Gwin this time for sure, but if anyone seems to be able to handle that kind of situation on race day it´s him.
Brook MacDonald is on it, roosting through the very first corner of the Leogang track. It was interesting to see Aaron Gwin following Brook more than once during todays practice.
Worlds are always a bit special and that definitely shows in the details of all the custom build bikes for this weekend.
The weather forecast for the next few days doesn´t look really promising, at least that´s what Siri Lehikoinen says.
With dark clouds closing in it had already started to rain by the end of 4X practice.
