You’ve likely heard that high sugar consumption has health risks - so how do you reconcile that with your need to fuel as a runner? Is sugar bad for runners, or is it a necessary fuel source for your fastest running and healthiest self? (Spoiler: it's the latter!) We brought on Cortney Berling, RD, MPH, to dispel common myths about sugar for runners.

  • Does sugar have the same impact on your blood sugar while running as it does at rest?

  • Do runners need to worry about the health risks of taking sugar in gels?

  • When and how should you fuel your runs?

  • Is it beneficial to combine different types of sugars on your runs?
