Lots of great replies. Thanks everyone!

[MENTION=440371]jrbz[/MENTION] that is incredible! I am seriously impressed!

I have a dedicated pair of running shoes (Adidas Duramo 8) and matched with a pair of Dr. Scholl's "Active Series" insoles. Darn near double the cushioning and they feel great! But again with me still hovering around 210 lbs, I probably resemble a big heavy lumbering locomotive out on the side streets, when I go running... But at least I'm still getting out there no matter what.

If I went on a nice smooth 40 mile bicycle ride (20 out, 20 back), and did it in 2 hours and 45 minutes (estimate) - - - I wonder how I would feel, how many calories that would be, average speed, etc... I have looked at that MapMyRide site and planned a route with only one large up 'n down hill. Everything else is pretty smooth. Hmmm.... At least it would be way more scenic and easier on my body than running a 10K!
