Still running three years post op

Just FYI: 75 year old female, former winning age group competitor in road races. Now 3 years post bilateral hip replacements for arthritis with about 1600 total miles of running 3-4 days a week up to 20 miles per week. X-rays look fine, no issues. Started racing again in January 2022 and although slower than I’d like, I am improving. I’ve regained my sense of balance, no falls. Life is good!
