As they say… “What you don’t know can hurt you.”   Running related injuries can wreck your racing season, trying to run through pain is never a good idea. 

Aside from learning how to reduce the risk of hurting yourself,  you will also learn how much fuel you need to consume day to day,  how to train your energy systems to increase your endurance and develop a sound training strategy.

Experience a weekend of assessments, education and training to bring out your BEST!

Serving you beyond expectation!

Experience a weekend full of  education that will elevate your training and racing to a new level! We have provided these clinics all over the United States for over a decade! We have yet to find anyone that offered the same level of education and clinical evaluations in one place!  Here’s what you can expect…

Your visit begins with an RMR (resting metabolic rate) assessment.  This is a precise measure of how much energy your body requires within a 24 hour period.  It also reveals how well your body accesses fat vs. carbohydrate.  This is critical bit of information.

We will then provide you with a video gait analysis, push the video into our analysis software and critique the way you run to ferret out errors that lead to injury and get in the way of your performance.  Then begins the corrections.  We’ll teach you how to effectively transition away from injurious errors in your gait.  Again, we have been at this for over a decade with incredible success in helping athletes perform optimally.

Then we will provide you with an “Active” metabolic assessment, commonly referred to as a VO2 max test.  This test not only reveals your metabolic turn point (threshold) and your VO2 max, most importantly it provides us with the information we need to provide you with a clear understanding of how, what and when to apply intensity in your training and racing.

We wrap up the weekend with some training , drills and more education.  We will teach you how to  self treat and care for low grade injuries.  Things you can do that will keep you training and keep things from getting out of hand.  This is actually one of the favorites according to our past clinic experiences.
