2:45 marathon would generally put you in the elite but non-professional class and give you a good shot of being in the top 10 for the smaller marathons. That's where many former collegiate runners would be able to do.

A good way to do comparison might be to do the percentile. 2:45 would put you in the 76 percentile.
