How Can the Science Help You Train and Race Better? Part 1

February 17, 2017

Recently, Travis Macy underwent a battery of tests at eNRG Performance in Boulder, Colorado.  We were intrigued to see what these tests were, why he decided to undergo them, and how he can use this information to change his diet and training to be an efficient endurance runner.  Dina Griffin, MS, RDN, CSSD, METS II & Leadville 100 finisher, joins the conversation to help us understand.

Here are the tests that they did:

  • Metabolic Efficiency (ME) testing
  • Lactate Threshold (LT) testing
  • Sweat Sodium Concentration Testing
  • VO2max Testing

In this podcast, we dive into the ME testing.  We will cover the other tests in upcoming podcast episodes.

  • Mark Cucuzzella

    great discussion ! thanks. keep moving the crossover point up. this makes you not only bonk proof but healthier.

    • Travis Macy

      Yep, Mark, this dietary and metabolic efficiency work is very important for runners. Keep it up out there!

    • Dina Griffin

      Thanks, Mark! Sorry I missed you at Low Carb Breck but fun to watch your talk online. Would love to meet up with you when you’re in Boulder next (or if ever!).

    • Scott Warr

      Mark, I just had my test done last week. Besides the technician recommending I take up quilting instead of running, I am very optimistic to hear Dina’s evaluation 🙂

  • Keith Brown

    Really looking forward to hearing Part 2 ! I think the Asics training lab in Osaka Japan performs this test. Costs about 200 bucks. If I get the work done there can one of you guys help with the interpretation of the results?

    • Dina Griffin

      I can help you, Keith. I would need the raw data file and it may be best to coordinate in advance so that you get way you pay for from the lab. You can email me :
