The team is divided into groups of 4 players.
A cone is placed on the court by each sideline for each team.
3 players from each team starts running from cone to cone with good speed.
The cones must be touch before running back.
When one of the players gets tired, the last player on the team can replace her.
The rule is that each team must always have 3 players running.

The run lasts for 8 minutes and then the teams take a 2 minutes break.
Then 8 minutes running under the same rules are made - then 2 minutes break and then the last 8 minutes run, which makes the total drill last 1/2 hour.

If one or more of the group's runs with less than 3 players they receives a penalty of 1 extra minutes running and only 1 minutes break.
The group can also be made of 5 players and then 4 players must be running.
