Why we reset two walls every single week.

Every Monday and Thursday, one wall closes at 8am and reopens by mid-afternoon with every problem brand new. Here's what happens in between, and why we do it so often.

8am: strip and wash

Four setters take every hold and volume off the wall. The holds go into the washing machine, the wall gets brushed and the tape comes off. By 9:30 the wall is bare.

10am: set and forerun

We set to a plan that keeps the six circuits balanced across the gym, so each colour always has enough problems. Then each setter climbs everyone else's problems and we adjust anything that's too hard, too easy or too reachy.

• Every problem is tested by at least two setters

• Grades are agreed as a team, not by the setter alone

• Anything that feels risky is changed before we open

Why three weeks?

After three weeks, regulars have climbed most of a wall and the holds are polished. With six walls and two resets a week, nothing stays up longer than that, and there's always something new on your next visit.
