Hi DBuzzy,
I use my BHR and THR hips in the hills in much the same way as I wore out the old ones – never was much of a racer but have spent years jogging (mainly on the downs) on technical trails, last year completing the Welsh 3000s challenge (33 miles, car to taxi) and last weekend the Edale Skyline, 33.5km across Derbyshire moorland, for the 4th time in the last 2 years. No reason you will not be able to get back on the trails, your’re still young!
Good luck,
Pete
