Running is the largest participation sport in the world with over 100 million recreational runners registered in the US and Europe alone. The majority of this population have started running with the intention of improving their levels of health and fitness but unfortunately the health and fitness benefits of running come at a price as injury rates are extraordinarily high in runners (1 in 3 runners report a running related pain or injury whilst preparing to enter a half or full marathon).

This website has been created to help runners avoid pain and injury by providing a simple assessment of their potential physiological and biomechanical risk factors for running related pain and provides solutions based on corrective exercises, technique advice and footwear selection.

5 Common
Running Pains


Knee pain in runners is pain located below or around the knee cap or on the inside or outside of the knee joint. The exact location of your pain will determine the diagnosis and category of knee pain but all running related knee pain share common risk factors.


Shin pain in runners is pain located on the front of your lower leg between the knee and the ankle. The pain can be directly over your shinbone (tibia) or over the muscles that are on the inner or outer side of the tibia. These muscles control the foot and toes and are the muscles most affected by an unstable foot and poor footwear choices.


Heel pain in runners is pain located in the plantar (sole) aspect of the heel and is usually diagnosed as ‘plantar fasciitis’. The pain is usually worse in the morning and after sitting down or resting for long periods and may be alleviated during running.


Thigh pain in runners is pain located in the upper leg between the knee and the hip. If the pain is located at the front and outside upper leg it is associated with stress or strain of the quadriceps and hip flexors. If the pain is located at the rear of the upper leg it is associated with stress or strain of the hamstrings.


Achilles pain in runners is pain located on the back of the lower leg from the heel to the calf muscle The achilles is is the largest tendon in the body and has evolved to be a ‘running spring’ to provide elasticity and propulsion during running and sprinting.
