The 20-minute session starts promptly at 08:10 in the Wurlitzer Hall (along from Bag Storage) within Woking Leisure Centre. The visualisation is designed to enable anxious and nervous runners gain focus, release unwanted muscle tension, overcome feelings of overwhelm and replace negative self-talk with positive messages.
