Hi Bicyclette,

Denise is right. Don't worry about what others do too much.

But also be confident that you can and will (if you want) increase your daily mileage. I now quite regularly ride 100 km+ fairly hilly rides (usually every Saturday), something I could only dream of doing when I started cycling two years ago and that little hill I had to ride up to commute back from work terrified me. Experience and practice will increase your endurance. It's good that you live on hilly terrain, you'll get stronger faster.

Good luck!!
