A friend of mine who frequently travels to marathons ran Lakefront as well. Here are some excerpts from his race report:
[color=rgb(0, 0, 0)]I ran miles 5-25 with a guy who had run it 11 times before, winning it in 1986 in 2:20 something, after you subtract the 1:45 (minutes) he had to wait for a train to cross the course. Also he finished 18th at Boston once, but he only volunteered that after I asked. Very nice humble midwestern guy. [/color]He was still pretty spry for a geezer and left me the last mile, so he ran a negative split of about 30 seconds vs my 20 seconds.
At first, I thought this might have been runner1, but it sounds like it wasn't.
