The cause of most problems is too much, too quick, even for seasoned runners.
Once you get over the initial ‘curve’ and find you start to achieve things you’ll start pushing yourself and may strat getting injuries.
IME its really important to spend a few minutes each day stretching and a few exercises on the supporting muscles to maintain the supporting muscles, in my case Lunges, Squats and Clam exercises.
Main benefit of running is minimal prep / faff / maintenance and expense, unless you go to the physio alot or get obsessed with shoe / clothing choices. There’s just as many nerdy gadgets to buy if you want them, but thankfully you’ll still struggle to spend more than a few hundred pounds on even the flashest bits of kit.
Also you get to places / see things you wouldn’t otherwise. Running around the less selubrious parts of your town at 6am in the winter is quite interesting.
