If runner, walker, or cyclist...

What is your favorite area to exercise in?  Personally I run through the hyde park area to ault park and then through mt lookout and back.  Most of my runs take place around Xavier University  Its a fun but hilly run. 

I bike the Little Miami bike trail.  Good rides are: Newtown - Bass Island to Lovelend and back.  or Loveland to Morrow and back/  or Morrow to Corwin and Back.  The hardest ride is Loveland to Lebanon.  I take the spur off the Little Miami River trail and ride up to the Golden Lamb.  It is best to do this in the morning.  The trail around Loveland can get crowded on the weekend.

I commute from home to work on my bike, so that's my primary exercise route, but when I get the choice, I do love the Little Miami trail. Blue Ash has a great bike/run route circle, but you have to look for it (Kenwood/Cornell/Plainfield/Glendale-Milford) , and Fairfax has a great bike trail on their northern border.
