How many calories do you think you could burn in a day? My guest, Ethan Hunger, picks a day every year to go to the max on everything physical: biking, running, swimming, HIIT… and logs 12,000+ calories in 24 hours. Why? For an awesome cause of raising money for a food bank. And he has built an amazing collection of such athletics-based fund raisers under the moniker “Hunger vs. Hunger”.
