New runner, looking for motivation!

Hey guys. I've just started running seriously this week - I've run 5k twice, and am absolutely loving it so far! I've been doing body weight workouts for years, so I'm in pretty good shape, but this is completely different than what I'm used to - and boy am I ever sore! So if anyone has some advice on things to keep in mind when starting out running, it would be very much appreciated. And if there are any other new runners out there who want to buddy up and share support, I'd be very much interested :)
