So what is CrossFit Endurance and how does this link to running?

Coach and Founder of CrossFit Endurance, Brian McKenzie, explains the pledge of CrossFit Endurance: Be UnScared. If you are not getting the results you want or if you don't perform, feel or look the way you want, allow us to provide the solution through our programming and community. CrossFit Endurance has been created by experienced athletes and coaches. We will provide only the best in proven methods. Long slow duration results in athletes being less powerful, less lean and more prone to injury, low energy and abbreviated sport longevity. We will make you faster. We will make you leaner. We will increase your power We follow the CrossFit model while adding precise training protocols for endurance. We will make you lift heavy. We will make your lungs burn. But we will make you happy!

Eat clean (lots of veggies, little fruit and starch, lean meats, essential fats, nuts, no grain, no dairy, no bread, no sugar, no GMO, no refined or processed foods), train like a freak and make every meter and every rep mean something. We don't have time to waste time; we do have time to accelerate ability. We welcome you to explore our website, experience our programming, ask questions and attend one of our detailed seminars around the world. We encourage you to stop thinking and start doing. We have revolutionized endurance training.

So why does this help with Running? How can Box Jumps, Pull Ups, Burpees, Push Ups, Olympic Lifting, Muscle Ups, Gymnastics, Sit Ups and Kettlebells help with your endurance? The argument for many years now has been that long slow running makes long slow runners. A conditioned athlete will be a stronger athlete and a stronger athlete will hold their form during fatigue. My belief is that conditioning programs such as CrossFit Endurance (if done correctly) will help prevent injury and in turn create better results from your training in the long term.

How? I have come across lots of runners over the years who run themselves into the ground. The mindset is more running, more results. Unfortunately the neglect they give their overall conditioning often leads to poor biomechanics or weak areas of the body (some areas more dominant than others), which, in turn, leads to injury. When I was training at Loughborough University under the watchful eye of George Gandy, during the winter months there was an emphasis on circuit training and performing powerful lifts in the gym. Although often quite funny to see a group of lean runners tackle the squat rack, the principles were spot on and very much in line with the idea of CrossFit. To see an example of the George Gandy method for conditioning click here.

Seb Coe the multiple Olympic medallist in 800m and 1500m came through the Loughborough University system and was one of the first middle distance athletes to put a focus on strength and conditioning rather than mileage. Coe was an explosive athlete and without high mileage and an all round approach to his running and conditioning ran some of the quickest times in history. But it is not just middle distance runners that benefit. I remember seeing Paula Radcliffe in the gym on several occasions in the build up to smashing the Womens World Record in the Marathon. In conclusion I believe a mixed approach to training is much better for an endurance athlete than just miles and miles of slow running. Make sure you keep the training varied, keeping the body guessing. Make sure there is intensity in the training in the form of circuits, fartlek running, interval training and recovery runs. Oh and check out CrossFit Endurance, it is here to stay and could well help you move onto the next level.

Run Well, Rich
