I am FINALLY able to announce that I’m accepting the #ALLINCHALLENGE (thanks to Coco Gauff for nominating me!!)!
It may not be Chris Pratt‘s get “Eaten By A Dinosaur” challenge (which I’m tempted to bid on myself), but I’m super excited about this package! I’m offering a VIP, once-in-a-lifetime experience to the World Cup at Killington Resort, behind-the-scenes access to my ATOMIC SKIING race and service team, a full Atomic gear set-up, a full access Ikon Pass, my signature Oakley goggles, U.S. Ski & Snowboard Team gear and more!! 🤯
Let’s come together to help the most vulnerable during this difficult time and provide food to those in need—kids, elderly and frontline heroes. I challenge Adam Rippon, KT Tunstall, Michael Franti and Spearhead, and Joel McHale to go ALL IN!
