Running ain't always easy. And with over 18 years of running experience - and 6+ years of coaching thousands of athletes - Jason wanted to share some of his biggest mistakes and the lessons that he's learned the hard way.
Why share these lessons? So you don't have to make the same mistakes! Trial and error works, but it's messy. Instead, eliminate all that wasted time and effort and instead focus on these Big 7 Lessons to avoid injury, gain endurance more quickly, and race a lot faster.
