Alternative names: n/a
Objective: To strengthen defensive walls
Typical length of drill: Repeated in 2 min increments
Materials needed: jammer panties, WFTDA track
Skill level required: must be cleared for contact
Description: Blockers pair up and stagger around the track. Jammers enter anywhere on the track at the starting whistle. Only one jammer at a time attempts to skate past/through a wall. Blocker walls skate at a slow pack speed and try to stop each approaching jammer.
Additional notes: The wall's inside skater must protect the inside line so no jammer escapes through it. She only steps as far away from the line as she can, knowing she can quickly return and stop the jammer. The wall's outside skater does most of the dirty work by swinging to the outside and back to her partner in order to stop the jammer on the outside. Remember to skate low and wide as to take up as much of the track as possible. The Great Wall of Ghina is not great unless it's large and in charge.
