Trust No One
The most important running tip I have is this; do not trust these running tips! More precisely, don't take anything I, or anyone else, tells you at face value. Do your own research, check the references given, and verify the facts that are presented. Ultimately you are responsible for your own health and wellbeing.
I have no formal training as a coach, nor am I giving this advice as a trained medical professional. Take these tips as information from one who has studied and experimented primarily for personal edification.
