I ❤️CARBS! (and so should you!)

I’d probably only be able to manage about 160 W for 10 hrs too, though I weigh 94kg and 10-11% BF.

You might be much better at fat ox than me.

I generally recommend out-consuming pure carb burn. Reasons:

  1. Reliance on carbs increases as fatigue increases. (assuming carbs are available)
  2. Hunger will mount as your kcal deficit increases throughout the ride. Carbs are more easily tolerated than dietary fats during exercise.
  3. If you do need any intensity at all, reliance on carbs will increase dramatically during those portions of the ride.
  4. Elevated blood sugar during exercise just feels better to me! Flirting with hypoglycemia off and on makes for a miserable experience when 8 hours into a ride.
