CrossFit for runners?
Why not? You're not one dimensional!
I'm not a member of a CrossFit box (they have their own lingo) but have worked out in one a time or two and have done their WOD using their app as well.
The first class, and in some cases, the first week is complimentary.
It has been my experience that they are protective of their sport, loyal to each other, a little bit obsessive, and occasionally weird.
In a word - we fit right in :)
Happy Running!
