Seahawks fan Tony Wiederkehr from Arlington, Wash., went Beast Mode during a cross country ski race in Switzerland on March 9th.
He skied the marathon race without using any poles. That's because he carried a football the whole way -- while wearing a full football uniform (including pads).
Wiederkehr said everyone was very receptive of his football attire and many were excited.
The Engadin Ski Marathon is annual event that goes through the Engadin Valley in Switzerland.
That's one dedicated 12th Man!
