Robert, I've made that exact journet the last 3 years, and no reason you can't, in fact you have plenty of potential as you're barely running.
Short term, gently add more mileage, make one run a week your "Long run" gradually lengthening this.
Mid term, add a tempo or speedwork session a week
Long term, 1 tempo, 1 speedwork, 1 long slow run, and as much easy pace running as you can fit in. (all added progressively, all run to the correct pace zones)
McMillan is a good website for giving you a guide on pacing. Most runners tend to run too fast on days they shouldn't. You save the fast work for the tempo and speedwork, everything else is "easy" pace.
