30 men and 16 women will qualify for the 2011 Oakley Arctic Challenge (TAC) – also being the trial World Snowboarding Championships. The best slopestyle riders in the world will qualify from the TTR ranking, qualifying events and wildcards.As the TTR ranking is getting more relevant every year, TAC decided to expand the ranking entry quota from the required TTR top 10 to TTR top 20 for the 2010 event. This was an instant success and gave a fair access to the event as well as giving more value for top 20 ranked riders. For the 2011 event, the top 20 men and top 10 women after Burton European Open will be invited to TAC. With wildcards and qualifying events, 30 men and 16 women will enter the 2011 TAC event.The main project for the 2010 TAC event, was developing and introducing the Snowboarding Livescoring System. It was an instant success among riders, media and spectators. TAC will keep pushing the progression of the system together with TTR and the other TTR events. For the 2011 event, the priority is to improve the slope design, keep pusing the judging format and start preparations for the 2012 World Snowboarding Championships. The events dates are February 14th to 19th. Prize money is 100 000 dollars. More info will be available as winter is approaching.
