How much do you want to run and how far?
If it's just leisure running to stay a bit aerobically fit then just get out there and run walk 20-30 mins a few times a week and see how it pans out, hopefully the issue will not resurface and just getting some mileage will start a trend to overall recovery and allow you to develop further ( I am assuming that the injury is not current and causing you immediate pain if you do try to run)
If you have a goal to do big races or fast times for you etc then it's going to take more effort and time as you are probably well aware
Sitting in a harness red pointing and jumping off anything high outside mainly aggravated my back so limiting what you do in your climbing week might also help
Sadly no one person's injury or injury history is ever the same so there will be no definitive answer but good luck
