Galen is in the very early base building phase. But given that, even out of shape and no marathon specific stuff, Galen could probably still rock 2:15 right now. Sage could rock 2:17-2:18. (on fast course, slow course minus 2-3 minutes)
A full build up and marathon specific workouts for a fall marathon, Galen would be able to run 2:09 in a place like Chicago but more like 2:07 in Berlin.
