I think I need to clarify ~ it's not Hills that are troublesome - I'm happy as can be to make it up a long climb & then take a little to recover.

It's the small little inclines in the road... a false flat, or a tiny rise that wouldn't even cause a blip on an elevation map that's sucking the energy from my legs. If I had to estimate - let's say 100-200 yards with a total incline of 20 feet. Tiny, tiny, tiny, but I just can't recover speed there. Waa
