What's so special about a 2:18 Marathon?

I run with a guy who has run 2:18 and 2 or 3 2:19’s. Whats so great about it? Try running a 1:09 half if you really want to know what is great about it, or a sub 30 10km. Then when you have failed miserably you will know whats so great about it. When I’m doing mile repeats at 5:45 he can tell jokes, laugh, tell a story and keep me on pace for the whole workout. Or he can pace me through a 35min 10k road race and not break a sweat. It is also lots of fun getting spotted 300m on a 1200 and trying to hold him off. Or watching him blow past you at 4:15 pace on the track.
I know 2:18 isn’t world class, but its damn fast, especially when that speed is on the same track.
