Is Boston the Hardest Marathon Major to Enter?
Boston has a reputation as the hardest Major to enter. Whether that is true depends entirely on who you are.
For fast runners: yes
If you can run close to the standard, Boston is the hardest because the cutoff keeps moving. A time that qualified one year can be rejected the next. No other Major rejects qualified applicants by a time margin the way Boston does.
For everyone else: no
If you cannot run near the standard, Boston is actually one of the more predictable Majors, because the path is clear: get faster. Lottery-based Majors like London or Tokyo can be harder for a non-qualifier, since entry comes down to luck no matter how you train.
The honest answer
Boston is the hardest to earn on merit and the most controllable through training. See exactly how close you are in the predictor.
Frequently asked questions
Is Boston really the hardest major to get into?

Why is Boston considered prestigious?
Because general entry is earned by a fast qualifying time and surviving the cutoff, rather than a lottery.
