## Resource

We wore the best shoe ever before this mailbag episode! We opened it up to listener questions, diving into tons of tricky and fun topics. Topics this week: David’s first run in the shoe that’s changing road running, our eventful weekend, Omega 3 supplementation, the types of heat training we like, our dream study design involving bicarb and fatigue resistance, leptin levels, upper body lifting, improving low testosterone levels, coaching specialization, helping a teammate with REDs, treadmill training, building up volume, rest intervals, preparing for summer heat, and more! Thank you for getting us off the floor for this episode. We love you all!
