Choosing the right cycling pants for women can be a bit tricky, but it doesn't have to be. The first thing to consider is the fit; they should be snug, but not too tight. Material is important too; look for breathable, quick-drying fabrics to keep you comfortable. Padding is essential for longer rides, so opt for pants with a quality chamois. Finally, consider the style and how it suits your personal preference and comfort.
In my experience, mountain biking tends to be more challenging than road cycling. The terrain in mountain biking is more unpredictable and requires a higher level of fitness and skill to navigate. Also, the constant changes in elevation, turns, and obstacles you encounter on a mountain bike trail make it a more intense workout. On the other hand, road cycling is more about endurance and speed on mostly flat surfaces. So, while both have their own unique challenges, I'd say mountain biking typically takes the cake in terms of difficulty.
