Reebok Butchers Classics is the biggest CrossFit competition in Denmark.
This year Butcher's Lab is bringing fitness back to Ballerup Super Arena. Ballerup Super Arena use to be the host of the European CrossFit Regionals back in 2012-2015.
You might have seen CrossFit on Netflix - now you have the chance to experience some of the fittest athletes live in the Arena.
(Children under the age of 12 will get free admission).
