I struggled with this for the past year and 3 months and ultimately, stopped the running. I was slow, but not as slow as I thought I would be. I liked running more than I thought I would, even though it was much, much harder for me than cycling ever was.
But in the end, I had too many chronic injury issues to continue. I don't want to spend my whole life at PT and dealing with all of this stuff. At 56, I should know better.
I still get cravings to run, but I have been walking 2x a week and doing core work, too, along with riding. It has to stay this way. MY hip/back is slowly healing, but when it started affecting my riding, I knew it was the end. I also found that running just wore me out so much, that I had to take a recovery day in between a running day and cycling. Again, I made the choice of what was more important.
