You are slightly quicker than me, but not a lot in it (my 10K PB is 53.15, and my HM is 2:00:36) and therefore got a very similar predicted time.
In reality, the predicted time was quite optomistic, and I finished my first marathon in 4:32:36, which I was reasonably happy with. I did, though, fall in to the schoolboy error of starting to fast (9-9.30 min/mile forthe first half), and suffering in the tail end. I think I would have been much better served sticking to about a 10 minute mile all the way round, and targetting a 4:20 finish or so. This time, I am training to finish in 4:15, and definitely going to pace myself better.
Which marathon are you doing?
