Rule the Road
Hard surfaces are especially tough on the body, even more so at longer distances like marathon. Protect against the effects of foot-strike hemolysis by replenishing your iron reserves whilst defending vulnerable joints like hips, knees and ankles.
Blaze a Trail
As trail runners know first hand, unpredictable surfaces mean your body has to be able to change direction quickly. This is harder to do with sore and tired muscles, so faster recovery will have you tackling the trails with fresh legs.
Fly Over Fells
The endless climbs and descents of fell running tax your body to the limits. Reduced lactic acid accumulation, improved energy metabolism and increased oxygen uptake will help you hit your peak performance.
