CrossFit, especially CrossFit Endurance make some big claims about their ability to train endurance runners without the need to do endurance running. “Our strength and conditioning approach for endurance athletes is unparalleled. We incorporate the CrossFit fundamentals of being constantly varied. Repetition is the enemy and results in a decreased ability to build fitness”

I have decided to put CrossFit to the test this year and I am going to do the Bay to City 13km fun run without doing any running training (apart from the odd 400m or 800m I do at CrossFit). I am also going to do it the day after doing workout 17.4 of the CrossFit Open (that should be interesting). If that goes well I will do a half marathon and see how I go. This is not the approach even CrossFit endurance would recommend just to be clear.

My take on it for FWIW is that if you want to be a really elite runner then you need to mostly run (and add some functional fitness for variety and additional benefits). If you want to be a healthy recreational runner then finding a better balance between running and functional fitness will lead to better overall health than doing too many km’s. If you want to do just CrossFit my expectation is that you will still retain a pretty decent ability to do endurance sports like running (much more so than if you were a runner trying to do CrossFit) as it really does allow you to maintain your endurance capabilities whilst working on other skills like strength, power and flexibility at the same time.

Let the games begin 🙂

I will be adding to this post later in the year as I have some results of this self experiment to post.
