RJRD, I agree with Jools. If you want to get close to 3 hours don't do any more long runs at anything close to marathon pace, but TBH I think you're going to be a bit over the 3 on this first one whatever you do. A VLM GFA target (3:05) might be a better bet (if you want to run VLM next year, obviously).
If it's your first race of any kind then pacing it for 3 is going to be a real problem - you'll think you're running nicely, it'll feel slow but it'll be inside 6:30 pace almost certainly. In fact you'll feel really good until you're well into the second half, then half a mile later you'll think you're the guy in the diving suit. That's just the way it is, but in the longer term there's some very fast races in you if those are training paces.
Bad luck Dan, hope it doesn't turn out to be Marigold-esque.
