From the "missed opportunities" files, in 2016 the cast of Friday Night Lights namely Taylor Kitch, Minka Kelly, Aimee Teegarden, and Zach Gilford participated in one of the Spartan Races which are physical and only slightly muddy runs. Only a few HQ promo photos exist I've found, most are the same ones repeated across dozens of sites in the same LQ instagram style and few good candids.
