CrossFit Level 2 Trainer

Ruth discovered CrossFit in 2013 when she was looking for a new challenge and a fresh way to push herself. It didn’t take long before she fell in love with the sport, the community, and everything that comes with it. Through CrossFit, Ruth met her business partner Dave, and together in 2015 they took on the exciting challenge of opening their own gym. What started as a passion for fitness and community has grown into something truly special — CrossFit PTBO has evolved and thrived over the last 11 years, and Ruth is incredibly proud to serve the people of Peterborough in achieving their health and fitness goals. When you walk through the doors at CrossFit PTBO, Ruth’s dedication to this community shows in everything — from the coaching on the floor to the environment they have built together.
