Athletes, what's harder riding up that hill or running up that hill?

[pfunk12]

For me, running is harder. Although I was a pretty successful runner(sponsored by a shoe company and successful at distances from 5k to the marathon), I absolutely hated hills. I never stopped to walk up a hill but that's not to say that I didn't slow down to a crawl! But on the bike, I love climbing. For some reason, it just seems so much easier to me. When running up a steep incline or long steady climb, I would think, "Gosh...this really sucks." But on the bike, I am sometimes sad when the hill is over.

Running is much harder for me...maybe because it takes longer than riding up the same hill, and I get hotter. I have very low gears on my road bike, so there would be very few hills I couldn't ride up, albeit very slowly. There are definitely hills I couldn't run due to their length or grade.
