Many runners ignore their upper body. We swing our arms when we run to help maintain balance and counteract the motion of our legs. If your arms and shoulders tire before your legs than your pace and your upper body will suffer. Runners should do strength training as well as running. Doing military press, lat pull-downs, bench press, one armed bent rows and curls will build upper body strength so your arms and shoulders can keep up with your legs.
You are probably tensing your shoulders when you run. Try to relax your shoulders and make sure you are pumping your arms when you run and not leaving them motionless by your sides. and try stretching your shoulders before and after your run. Happy trails!
