strength training helps a lot in preventing injuries. I've been through years of achilles tendonitis and finally got rid of it mostly by doing leg/calf strength exercises.
thank you for this. I've been dealing with plantar fasciitis for a year+, finally got it to go away ~5 months ago and got back into running, and just in the last 2 weeks have noticed gradually increasing pain in my achilles and I'm absolutely devastated at the thought of battling another chronic injury.
I've been running for 12+ years and after going through plantar fasciitis and some other issues (went to a very good orthopedic sports clinic that helped me a lot), getting a Theragun and using it every day was amazing afterwards, especially for calves (that can help with achilles tendonitis) and for your foot for plantar fasciitis).
