I may be older and have gained a few pounds but I still love to spend time playing on the hills. Back when I was younger and much lighter and doing some racing I always enjoyed a hiller course. Sure the hills don't seem as easy as back in the day and I have switch to some easier gears to help out, but oh how fun they still are.
