Don't blame your injury problem on high mileage and strength training. I would first check your shoes, mechanics, terrain, pace or nutrition status. I don't know what kind of "strength training" you do but the whole idea of hill training is so that you can "strengthen" necessary muscle groups in a balanced way, not just isolated fashion like using weights, to eliminate possibility of injuries.
HRE, Kim, Tinman and others who were concerned for my father:
Thanks guys, but he's doing really well--better than we all expected! Just to show how amazing human potential is... He was literally at his death-bed 3 months ago. When I went to see him 3 weeks ago (when I was back in Japan for business), he could barely "sit up" (not stand up), and now he's walking up and down the hallway. Really appreciated your concern and well-wishes.
Those who were interested in the Lydiard Foundation and hill training images on the website:
Really sorry, I'm still way behind; but still working on it. I was hoping to get it up by Boston but it would probably take a bit longer. Bear with me... By the way, I'm taking two ladies to Boston this year; one is my wife who is a 3:47 marathon runner, the other is a 2:22--number one seeded, Reiko Tosa. She could write a history to become the first Japanese female runner to win Boston... Her team's assistant coach went to NZ, just as I did, and stayed with Lydiard for 10 months, studying the Lydiardism.
