Are you using a treadmill for returning to running after an injury?

Today I was out on a run and I was thinking about treadmills versus running outside. To be fair, I was actually running outside during this run. It seems like most of the runners who sign up for the Fast Track challenge, or who call me for a second opinion, the majority of them like to run outside. I have a question for you. If you got an overtraining injury like a metatarsal stress fracture, calcaneal stress fracture, or a tibial stress fracture, plantar plate sprain, the question is... Are you running on a treadmill to ease back into running, or are you just running outside, to see how running feels after your injury? Are you using a treadmill for returning to running after an injury? Well, that's what we're talking about today on the Doc On The Run Podcast.
