Taking the best to new heights

Harry Tanfield

Road and track cyclist

“I find the information about my blood values at different points in the season very valuable; it helps me guide my training and monitor the training load. Equally my nutritionist, coach and gym coach use this information to better enable them to direct my training. It’s a complete team effort and Forth Edge makes this possible. Plus the test is super quick and easy.”


Tom Evans

Ultra runner

“As a professional athlete I need to ensure that I’m looking after my body throughout the year. Being an ultra runner, my training volume is high (225km average per week) and it’s essential to stay healthy. This is where Forth Edge has helped me; my first test showed that my iron levels were low and I have now been able to improve them which has really helped my performance. It’s an essential part of my training and racing as an endurance athlete!”


Susie Cheetham


“The more Forth Edge results I’ve had the better I’ve been able to compare previous results and therefore discover what is normal for me. Last year I had elevated white blood cell results and inflammation compared to previous results. It came 5 weeks after a bad cold that I thought I was over but turns out I wasn’t and I could adapt my training accordingly.”
