Pain during running

I’m pretty new to running (10 runs logged in Strava) and most of these runs have been is zone 2, sometimes lower end of zone 3 and I feel like towards the end of my runs I start getting pain/fatigue in my shins, ankles, and bottom of foot before I’m actually tired and need to slow down or stop due to breathing tiredness. I hope that makes sense and I can get some help. Thanks!
