This British Hero WOD was designed by CrossFit NW1 (Conwy, Wales) in memory of member and athlete Lt. Garreth Jenkins of Colwyn Bay, Conwy, who collapsed at the Commando Training Centre, Lympstone, Devon, while on a 30-mile (48km) march on Thursday, May 28, 2015.

Lt Jenkins, who was in his mid-20s, died during the so-called "30-miler" march, the last major test undertaken as part of the 32-week Commando course. Trainees must complete it carrying at least 32lbs (15kg) of equipment in a maximum time of eight hours.
