In the second episode of our Christmas Calendar, Christmas in Unisport, Jakob and Joltter go head-to-head in the first of many challenges. Today we have the crossbar challenge, where there rules are simple; Hit the crossbar the most times and win. There is, of course, a Loser Shirt to prove who lost the challenge. But who will wear it? Join us today, as we look at the new Adizero and do the Crossbar Challenge.
