Certainly not rushing in. In my experience delaying was the absolute worst thing that I did. It meant that the rehab to overcome shortened muscles and tendons was that much longer and painful.
Exactly 12 weeks after surgery I managed a super sprint triathlon and the overall win – so 2 miles at 8.2 mph is achievable.
There are great days ahead! Get it done and rehab well and you’ll never look back. Best of luck
