Groups of 4, with 2 on one end and 2 on the other. One ball on the opposite side
Have the cones about 5-8 yards apart, with about 10-15 yards to the other group.
A and B at the same time will sprint to their cone, sprint back to the start, then back to the second cone. As they are approaching the second cone (for the second time), the player across from them will serve a 50/50 ball for A and B to battle.
As soon as that ball is played in, C and D will begin their sprints and then receive and ball from A or B to go into a 50/50 ball for.
Players can team up with a partner on the other side and keep track of number of 50/50 balls that have been won, team with the most at the end wins.
