Plenty of time to accomplish and even to do a solid time.
Once a week do a long run and try to add an extra 10% distance each following week. Never go beyond 32kms though.
2 times a week do speed based sessions, for example 1km reps on Tuesday and 400m reps Thursday.
Another excellent session is fartlek running. Continuous running but with sturges in pace. My favourite fartlek is Mona fartlek. 90s on/off x2, 60 on/off x4, 30s on/off x4 and 15s on/off x4. That equals 20minutes of running. Add in 10min warm up/down.
Remember a marathon is a long way but with the right consistent training you'll smash it!
