Here's a question for you all.
I run for exercise, and I walk around briskly, like walking my dog and stuff. But a couple of times recently I've gone on a long (about an hour and a half) walk with a friend. She's super fit (skinny, athletic, multi-sport type). She walks briskly and has to slow down to my speed....
But for some reason, I find fast walking much less comfortable than running. When I run, nothing hurts, but when I walk briskly, my hips hurt. At the end of a long walk, I tend to be sore. At the end of a run, I'm tired, but I don't hurt.
When I'm on the treadmill, I really don't like to walk faster than about 3.3-3.5 mph. 3.3 is comfortable...
Am I strange? I thought that running was "harder" than walking and that being fit for running would make me fit for walking. Walking doesn't do much cardiovascularly, but it makes my legs hurt.
