Marathon races are traditionally about winning, not about records, and times aren't really comparable across courses.

The Marathon record doesn't even require the course to be flat (there are limits on the elevation difference for it to be recognised as a record).

Drafting isn't massively effective in running. A Marathon in 2 hours is 21 km/h, and in cycling you wouldn't really bother drafting at that speed.
