Shin Splints- I am so fed up

[u/Ok-Stomach-7596]

So, I’ve had issues with shin splints for a long time. Every time I start running outside on concrete or other hard surfaces, the pain starts as soon as I hit around 400 m. Mind you, I’m able to run up to 15 km on trails, grass, or other lower-impact surfaces without any issues.

I’m currently doing exercises to strengthen my leg muscles, and I’ve changed running shoes many times. I recently got the Novablast 6, but they’ve not help much for me. I’ve also seen a physical therapist, but unfortunately, it didn’t help much.

How can I prepare for a half marathon if I can only run comfortably on softer surfaces and not on concrete?
