This is exactly what I’ve been trainign for since the end of January, just doing 3-4 miles twice a week (as well as biking) for the first month until I was comfortable.
I then moved away with work 2 weeks ago to Northamptonl wasn’t too sure of what the area was like to run round so I joined Fitness First and got on their Body First Programme (bonus of no joining fee, pay £30 for 3 personal trainer sessions – normally £90, then you get a refund on the £30 and they include the first month for free too!!)
Had my first session with the PT (it’s a lady too :wink: ) last night and she set me up on speeds etc and talked through a training regime that includes going for one proper outdoors run a week at about 8 miles to start with when I feel comfortable doing it.
It’s definatley given me the push I needed and I’m adamant I’ll get sorted and crack 2 hours – doing 8k in 45mins at the mo, so I can;t see it being an issue if I’m disciplined.
Bear in mind that until I started running at the end of January, I had run any distance at any kind of pace since High school (at least 16 years ago), so it’ll be no worries for your wife if shes generally fit to begin with and motivated.
