Today's episode is a Q&A where I answer questions that have been submitted by listeners. The questions I answer in this episode include:

• I'm a college coach and my athletes just started double threshold days. What should fueling and refueling look like around these sessions, and should they be taking in carbs/electrolytes during?
• I'm a high school runner with a big appetite, and I find myself comparing how much I'm eating to friends and family and feeling bad about eating more than them. Do you have any tips on how to deal with food comparison?
• Do you have any advice on how to take gels? I've never eaten anything while running before and I'm not sure where to start.
• I have dealt with chronically low ferritin for years despite supplementation. My ferritin recently increased from 20 to 23 after 3 months, and I was hoping it would increase faster than that. Is this typical? Should I try to get an iron infusion?

Thanks so much to everyone who has submitted a question! If you would like to submit a question for the next Q&A episode, so you can do so on my website HERE.
