☀️ Our YOUNG NINJA WARRIORS classes will be running today while following our Hot Weather Procedure.☀️

To keep everyone as safe and comfortable as possible, we will be:

• Increasing air circulation by keeping the roller shutter door and fire exit door open, with our industrial fan running throughout the session.

• Enforcing regular rest and water breaks.

• Limiting training to ground and rig level only. There will be no climbing around the back of the Warped Wall complex and no use of the Angled Wall.

• Focusing on skills-based training, with no continuous Flow Course runs.

‼️ Your Child Must Bring A Water Bottle ‼️

We do however, totally understand if your child has had an exhausting day at school in this heat and is unable to make class.

Best wishes,
Dion 💪🏼😃👊🏼
