A friend and I were discussing this weekend the amount of middle aged men marathon training with a gut in our training groups We are both around 40 years of age and been in marathon training group for quite a few years observing this.
Many of the guys we see in marathon training groups run 35-45 miles a week year round. Age from late 30's to upper 40's. Not high mileage by any means, but creating a significant calorie deficit with the miles. These dudes are married, getting up early to run mornings before work. Hence, they aren't out binge drinking with the boys taking on alcohol calories.
How can someone be 25-30 lbs overweight when logging that cardio activity? Is their diet, just terrible? I don't understand how they can train for marathons and still have a gut if there not out getting ripped drinking several times a week?
