I always like to praise my clients for the accomplishments they achieve, no matter how big or small they are.
A number of my clients this year have wanted to take on new challenges and for them in meant upping the distances they were running to include marathons and ultra-marathons and events.
Interestingly enough, most people who complain about knee injury caused by running are not runners themselves. They usually make it seem that knee injuries are inevitable for runners and that runners are literally running their knees to the ground with every step. However, knee injuries are not inevitable, though they are common and can be easily corrected. Knee pain should not cause you to automatically quit running.
