You have to be careful with running as its so easy to get injured. You have the aerobic engine which is transferable but need to build and train your running muscles (mitochondria and strength), tendons and bone density.
When I started running again a couple of years ago, I started with one 30min steady run a week and built up from there and added interval training after about 2 months. Try and do as much running off road as well.
