Combining endurance and strength training has always been tricky, because of the “interference effect” between the two types of workouts: The classic study on concurrent strength and endurance training was published by Robert Hickson in 1980.

I’ve done a full Ironman (Couer d’Alene) and several halfs. I’ve done a dozen marathons. Always eating lots of carbs.
