The calorie expenditure for road cycling and mountain biking can vary based on factors such as intensity, terrain, and duration. Generally, road cycling on flat terrain at a moderate pace can burn around 400-600 calories per hour, while mountain biking on varied terrain with hills and obstacles can burn around 500-800 calories per hour. The higher calorie expenditure in mountain biking is due to the increased effort required to navigate the challenging terrain and obstacles. Overall, mountain biking tends to result in a higher calorie expenditure compared to road cycling. **

Whether or not you should stop mountain biking depends on your personal circumstances and reasons for considering stopping. If you are experiencing physical pain or injury from mountain biking, it may be wise to take a break and seek medical advice. If you are feeling burnt out or no longer enjoying the activity, it may be beneficial to explore other forms of exercise or outdoor activities. Ultimately, the decision to stop mountain biking should be based on your own well-being and enjoyment. **
