Obstacle Course Racing (OCR) requires specific training just like running a marathon or racing in a triathlon. However, the skills required are very different. To do well at obstacle course racing you will first need to have endurance. Add to that good upper body strength, balance, agility and grit. The great thing about OCR is that with the addition of weighted carries and other strength orientated obstacles, it helps to level the playing field so while running may benefit the smaller lighter athlete, the carries benefit the larger stronger athlete.
