LOVE - Simply that I am able to do it. The satisfaction of completing a 10 mile and feeling just fine afterwards. Seeing my neighborhood close up and at a slower pace then I experience through my car's windshield. It's also nice to hear my dh brag to people about how active and in shape he thinks I am.

HATE - Those days when I just don't even enjoy a 2 mile run - and for no apparent reason. A windy uphill run. When the training schedule calls for a longer run and I'd rather be on my bike instead. Somedays there just isn't enough time to bike to and from work and still get in a 8-10 mile run afterwards.
