This 6.3 mile (10k and small change) loop is mostly on road but goes through a pretty golf course. The golf course section seems to stay in usable condition all year round.
The first 2.1 miles are along the familiar Port Lane, then there's a couple of hilly miles, and the last 2 miles are downhill and flat all the way home.
So as long as you can make it to the 4 mile point, you should be able to make it home.
