Are you sure? That's really moving.. if you have that sort of aerobic fitness already (and 10 minutes is aerobic) I'd just mix it up. Run longer and slower.
The first week run every other day. For aerobic gain you really need to be running over 20 minutes at a continuous effort, so fo that 3 times a week, then add 5 minutes and do 20-25 minutes every other day, then add a longer run, then run 2 days out of 3 and just slowly add more volume, longer runs, more runs etc and vary pace.
