I was always a road runner, and the one time I tried the treadmill, I fell off!
However, if you have access to a track somewhere, that may be a happy medium if you're not ready to make the jump to road running yet. I know in my case, actually registering for a race and paying the money is also a GREAT incentive to take steps towards preparing for a race as well.
You're on the right track! Just keep going! :)
