I agree. I've seen marathon-running fanatics who are great on the track, but couldn't do much else. I'd rather test stamina in an obstacle course/ruck march type scenario than a straight run. Case in point, I have messed up knees from running too much. I can't run long distance, but I can put on full body armor, pick up 60lb of machine gun and ammo and run from cover to cover all day long as long as it's in short dashes (20-30 yards here and there) or a hundred yards at a time.
"And Shepherds we shall be. For thee, my Lord for thee. Power hath descended forth from thy hand, that our feet may swiftly carry out thy command. So we shall flow a river forth to thee and teeming with souls shall it ever be. In nomine Patris, et fili, et Spiritus Sancti. Amen."
