That’s really good to hear @WedgeC. I am at the beginning of my running restart – 3.5 months after surgery, with just 3 short run/walks under my belt and an intention to build up very slowly. So far, there’s no soreness or stiffness, and the stride feels normal. Inhibitors are largely in my brain as I do worry what would happen if I fell awkwardly. Can’t see me entering a trail race anytime soon. I have chosen to restart my running on trail to reduce the impact on the hip, but am so far selecting flat, wide routes with that I know have no tree roots. Not sure that I will stay on trail once they become the usual mud fest we get here in late winter / early spring. Good luck in your event. Modern hip replacements are fantastic.
