It's up to you really. If you want to do it it's easy. If you'd rather faff about running 7 odd miles a week for ever then thats up to you.
When I started I went from 0-6 miles in 5 weeks. And I'm the most un sporty person in the world.
My girlfriend went out and ran 4 miles on her first day.
My ex father in law did 5 miles on his first day,which was also his first days training for his first marathon 4 months later. No previous exercise.
And my ex's cousin ran a 45 minute 5 mile race with zero training, no other sports, nothing. Apparently she wasn't bad at running at school some 30 years before.
If you want a kick, (devils advocate...), i'd say if you've run for 30 mins but haven't even covered 3 miles in that time then your fitness isn't dwindling, rather you have never been fit. I've done 15 marathons and two ultras and iv'e sure as hell never been fit. I was just conditioned to the distance.
