Concrete is not my friend. Ran a tad over 4 today downtown and now I feel like I ran 12, ugh. Gonna need to hop on the bike tomorrow to get my legs back to normal now. After I ran my long run Sunday that following Monday morning I went for a nice moderate paced road ride and OMG what a difference that made. My hips weren't hurting, no tender anything after the ride. I usually have sore hips after a long run like that. I just thought it was odd the bike seemed to help so much. Yay more reasons to ride my bike Who am I kidding, like I NEED a reason, LOL.
