Question: how long does it take to get back into running?
Answer: Use a fresh approach to your training. McMillan suggests runners approach the comeback in two key phases: 2 to 3 weeks and then 4 to 8 weeks. For the first phase, he prescribes runs of 15-20 minutes for 3 to 4 days a week. He then slowly increases run time in weeks 3 to 8.
