Does anybody remember the Bostonfest Marathon? It was a race that was run I think a couple of times back in the 80's. I ran it in '83 but don't remember much of the course except it was totally inside Boston & I kind of remember part of it might have been run down Storrow Drive. I'd love to find a map of the route but the only thing you can find online is a few anecdotes about the race & how many people got treated for weather related issues.
The only one who comes to mind who might know about that one would be Henry...
I don't remember much about it . I ran Boston several times in the early 80's and lived in southern Maine at the time So, I can't be too helpful. Try Google.
