Tread Lightly Running Podcast

If a supplement offered to make you run faster and lower your risk of injury, you think it’s too good to be true. But with carbohydrates during your run, it is true! Fueling with 60-90 grams of carbs per hour on long runs and races will improve your performance and reduce injury risk. We delve deep into the science around gels and sports drinks during your runs. After listening, you’ll feel more confident about how to fuel your runs to race your fastest and feel your best.
