Chessboxing

I've found my sport: chessboxing. Alternating rounds of chess and ... boxing.

Excerpt:
The rules of the game are simple. Bouts are composed of a maximum of 11 alternating rounds of chess and boxing, with checkmates or knock-outs resulting in instant victory.

Fighters can also triumph if the boxing match is stopped by the referee, or if their opponent times-out at the chess board.

Chess rounds last 4 minutes each, and each player has a maximum of twelve minutes to make all their moves.
Frank Stoldt and David Depto

If there is no winner after 11 rounds of punching and castling, victory is awarded to the fighter with the most points in the boxing ring.
