in addition to enjoying riding, i ride to lose weight. i was wondering how much carbs a body burns in any particular time as you ride. like say i have 15g of carbs before a ride. i ride 17ish miles, doing 15-18mph (on a mountain bike), did i burn all those carbs, or are they going to get packed away as fat when i go to sleep shortly after my ride. is there a way to figure out if i burnt all those carbs out. i noticed that if i limit my carbs too much my legs are very weak.
anyone have any info to help me out?
