Whilst you’re here… Join the CALM Running Collective

As we carry on planning the best on the day supporter experience in the biz, check out and join the CALM Running Collective. It’s a place for runners of every age, shape, and ability – we share training tips, encouragement, stories, failures and successes. It’s about a shared passion and mission, using exercise to look after yourself, and each other during these confusing times.
