I haven’t run Boston. I ran qualifying times in the ‘80s but never got around to it and seemed like I had endless time to do so. Then life happened and by the time I got back into marathons starting around 2009 my times had slipped and then I shifted to trails/ultras. Have to admit though, if I could qualify I would love to run Boston. My sister ran it, is glad to do it, but like tigers337’s comment the point to point nature of the course made buses as much of an effort as the run. No interest in other majors though. Chicago was worst experience of my 30 or so marathons/ultras because of having to pick through thousands of people who had placed themselves in faster corrals than they should have. In the mid-80s there used to an Emily & Pooh 10k that ended on the Tiger Stadium warning track. Did that a couple of times then sat in the bleachers in the afternoon.
