My Wahoo Roam claims I burned north of 5000 calories a day. Likely so.

I rode each day' ~100km fasted. Only ate supper and couldn't get more than a can of spam down.. maybe a couple of hard boiled eggs the 1st night. Roughly 1000 calories a day and all the water I could drink.

North of 15,000 calories burned while fasting, little more than 3000 calories consumed over 3 long hard days. I gained 3 pounds body weight. lol

My preferred food for rides is pemmican - you cannot beat the energy for the weight. I ate spam on this ride purely as a convenience.
