A new rivalry is budding in the sport of OCR and is in part it is due to the Battlefrog Series removing its weekend races. That has caused a lot of races to move their primary series to Spartan races. With that move, a very athletic and fast group is moving to Spartan Race, the Masters Division. This past Saturday at the Spartan Super at the Wintergreen Resort (The Vertical Mile Monster) was a debut to showcase just what the Battlefrog Master division will be bringing to Spartan in 2017.
