This is not intended to be an exhaustive list, but I think you get the picture:
1. Held on Patriot’s Day, it’s as ‘Merican as apple pie and baseball.
2. It’s got perhaps the deepest HJ field of any marathon in the world so there are lots of people to run with.
3. The number of spectators is unbelievable. Helps that it’s held on a holiday in the middle of the day and runs by Fenway right as the sox game ends.
4. The course is a fair but challenging test that has withstood the test of time.
5. You have to qualify to get in. The qualifying standards are “easy” enough that just about anyone can qualify with dedication, but still “hard” enough that it’s a significant accomplishment.
6. The last ~600m on Boylston from Hereford to the finish line is just something you have to experience to appreciate.
7. So that when people inevitably ask you can say, “Yes I have run Boston.”
8. As Big Papi said, “[Boston] is our f&cking city.”
