Running is having a big moment. From record-breaking marathons to run clubs filling city streets. But whether you’re training for your first 5K or chasing an ultramarathon, the sport can feel daunting. How do you push yourself without burning out? What should you eat to fuel your body? And what’s really going on in your brain when you catch that so-called runner’s high? To take your questions on how to run smarter, faster, and longer, Just Asking was joined by Krista DuChene, an Olympic marathon runner, running coach and registered dietitian, Dr. Kevin Masters, a clinical psychologist at the University of Colorado, Denver who studies the psychology of physical activity, and Allison Hill, founder of Hill Run Club in Toronto.
