Kenno .... like they all say, the time goal doesn't really matter, because it's your first marathon, so you'll get a PB. If you are going to run Oxford, just jog it. I know you are capable of a fast half marathon, but the weekend before a marathon is not the time to be running a long hard race. You will suffer muscle damage that won't be properly healed in time for Amsters. What's the point in risking it?
For me finish time is not the most important thing in the marathon. It's a bi-product of your training. The most important thing in the marathon for me is to have a positive experience. Cause if you get de-moralised its a long old slog of misery and pain. I've experienced those kind of marathons.
With your running background and current fitness, it wouldn't be unreasonable to target the sub4 in the Dam, but use it as a guide to pace yourself to, and just enjoy the race. In Oxford, if you know anyone who is targeting a PB)like a sub2 then why don't you offer to pace them?. That'd be fairly easy paced for you and you'll have no soreness the following day. It'll be a helpful workout/long run as part of your taper.
