That's wicked! Congrats! I used to run a lot and made the switch from the elliptical back to running in January. It's 1000x harder, even when I did like level 16 resistance on the elliptical...haha. I find I like it better too because I'm competing with myself to get a better mile time or finish a 5k faster or whatever - it's very addictive!
Congrats again! You made me want to go running now...
