From pirates to gladiators and frat boys to nerds, participants dressed up in an assortment of costumes and stomped the Pulaski track during the Viking Challenge, July 29 on Pulaski Barracks. Teams consisted of up to 12 people with 150 teams competing. The Viking Challenge is a 24-hour run or walk marathon that raises money for the Landstuhl Fisher Houses and other organizations in the KMC.
