To bad you dont like jogging as it is considered one of the most, if the most, efficient form of burning calories in the least amount of time compared to cycling, weights, swimming, etc.
Dont call it off to quickly, wait til you "feel" lighter and your endurance develops and give it a shot to jogging. Nothing better than mix and match to take a break from the bicycle. I dont know about other people but sometimes blending different sports helps maintain a positive attitude toward workouts. Also, you gain to target different muscle groups that cycling does not workout efficiently.
