Rookie Rumble 008: Grappling Edition is an In-House Grappling Event in Hiro Gym Vienna. It is run in collaboration between Hiro Gym Vienna and Mojitsu Events and provides grappling matches for all levels of experience.

This event consists of two parts:

  • The Rookie Rumble Pro Card: a selection of super fights featuring some of Austria’s best grapplers in selected 10 minutes EBI rules grappling matches

In an effort to promote women’s grappling, we offer free registrations to all women willing to compete in the amateur event and are opening our main card to any bluebelt with competitive experience willing to step up.

Registration includes a free T-Shirt, as well as a welcome bundle and specifically designed high-quality medals for the top 3 in each division.
