Degrees of Seperation

You want to skate ski,  but.....

No snow.

SO,  you get roller skis,  but....

It's snowing outside??



JUST how many degrees of separation form a root sport CAN you have??

(In fairness, these get used to do Lactic Threshold testing on the Nordic guys.... who are really the aerobic monsters of the universe. It is getting a bit "removed" after a while.)
