Is 10 miles in 30 minutes cycling?

Could you please clarify your question? Are you asking if it's possible to cycle 10 miles in 30 minutes? If so, it's definitely achievable for an experienced cyclist or someone who is in good physical shape and has been cycling regularly. However, it's a relatively fast pace, and not everyone will be able to maintain it. It would also depend on factors such as the terrain, weather conditions, and the cyclist's equipment and fitness level. So, in short, yes, it's possible, but it's not necessarily easy for everyone.
