HolteThe wallride on the left looks sick. Haven't seen a really cool comp wallride since Wally's last gold at X, which was 2012...ish...?
Also, can someone explain the deal with the Olympic Test Event? It's just a proof of concept with no FIS points, right?
It's a FIS World Cup event. FIS has a requirement to hold at least one World Cup event on any Olympic venue, prior to the Olympic year. These are known as "test events". It is run by FIS as a standard World Cup event, and counts as one for points etc.
There will be a Halfpipe test event at Phenix Park next season. They may also run another Slopestyle World Cup next year, but they don't necessarily "have to", as this one will fulfill the FIS test event requirement.
(There were similar requirements for Sochi, however the crazy weather and lack of snow over there forced them to cancel the scheduled Slopestyle test event in 2013, so the Sochi Games scenario, where the first event on that course was the Olympics itself, was a very rare anomaly.)
