Hi TJ – check out my previous posts for details, I had a Birmingham resurfacing 5 yrs ago and was jogging at 8 weeks and racing 5k in 23:45 around 9 months. I also have a ceramic THR from May 2017 which allowed me to run at 8 weeks and back to speed in about the same 9 months. I also spent December/January 2018/19 limping around with thigh pain in the THR leg which stopped all running. Rest was enough to repair whatever I had done and all is fine now. Speed is currently less but am training more for aerobic endurance, as well as being just turned 69 years old (which seems to make a difference…)
Good luck!
Pete
