• Online advice on prevention targeting modifiable risk factors not effective
• Advice: focus injury prevention on runners with a history of injury
• Forefoot landing may lead to more lower leg injuries

Online injury prevention advice for runners does not prevent injuries. This is the conclusion of a randomised study with over 2300 recreational runners who participated in 2017 in three Dutch running events. Half of them got access to a website with information about modifiable risk factors for developing injury, such as body weight, walking distance and -frequency, forefoot landing and tips on shoes and soles.
