Without knowing how fit you are it's hard to say whether you could run that or not, but i'd say most people capable of running the distance should be able to cover that in 25 minutes after a few weeks.
If you actually trained, you might get it down to 20 minutes; but as has been mentioned, that's fairly quick.
I'm not gonna be pushing myself to run further than that, so was thinking once I'm doing that distance, the difficulty would wear off and I'd start knocking the time down, maybe add in a mo farah sprint finish for the last quarter of a mile which is down hill.
25 minutes would be fine as some days in the car it can take over half an hour.
