There's a few "hills". I usually seek them out actually. But most of my commute is in a river valley so there are a few ups and downs no matter what. I went from a 35mm cross tire to these and the conti's are almost double the weight. Pumping them harder made a noticable difference. Googling now tryong to find the "Cyclocross Plus" tires in the above advertisement. No luck so far.
