The up hills or the down hills?

I'm assuming you live in NW Arkansas, so those hills are to be dealt with. But the Bicycle Coalition of the Ozarks is pretty active, so lots of other folks are finding their ways and they may have tips for you.

Ultimately, the only way to know is to try. What have you got to lose? The hills may slow you down a bit, but they won't stop you. And the more you ride them, the faster you will get up them.

My last commute had one hill that was steep with a 20% grade for part of it's climb. It was a challenge, but I always made it to work. The secret is leaving 15 minutes before you need to. That gives you time for reduced motivation days and flat tires.
