Boston 2027: the cutoff rises to 5:17, and downhill counts

To enter the 2027 Boston Marathon you no longer need just the qualifying time. For direct entry you must beat your age-group standard by 5 minutes and 17 seconds. The result: 8,019 people who had a qualifying time were not accepted. The race is on Monday 19 April 2027. If a spring marathon is on your list, this number changes the plan.

How the cutoff works

The standard is the time your age group must run in a certified marathon. For men aged 18 to 34 it is 2:55:00, and for women in the same group 3:25:00. The 5:17 cutoff takes that margin away: a man in this group must run under 2:49:43, a woman under 3:19:43. The figures come from the Boston Athletic Association (BAA) and from the race listings we checked.

Marathon Handbook says the 2026 cutoff was 4:34. We could not find the 2026 table on the BAA site to confirm it, so we report it as their figure. The direction is clear anyway: the margin has grown, and a time that was enough before may no longer be.

Who gets in, and the odds of the draw

Runners who have a qualifying time but miss the cutoff enter a random draw for about 1,000 places. According to the BAA the field is around 30,000, and 8,019 qualifiers were not accepted. With roughly 1,000 places for 8,019 people left out, the odds are about one in eight. That is our arithmetic on official numbers, not a promise.

One source gives 9,019 people left out instead of 8,019. We use the figure from the BAA table, the one we could read ourselves. The draw is not a one-off: for Paris 2027 we explained how the lottery works.

This is the change we find most interesting, and the one the headlines mention least. For verified times on courses with a net downhill, the BAA adds a penalty. Between 1,500 and 2,999 feet of net downhill (about 457 to 914 metres), five minutes are added to the time. Between 3,000 and 5,999 feet (about 914 to 1,829 metres), ten minutes. Above 6,000 feet (about 1,829 metres), the time does not count for qualifying at all.

Here is an example with the BAA numbers. A man aged 18 to 34 runs 2:49:00 on a course with 2,000 feet of net downhill, about 610 metres. With the five-minute penalty his time becomes 2:54:00. That is still under the 2:55:00 standard, so he qualifies, but it is above the 2:49:43 cutoff: he goes into the draw, not straight in. On a flat course, with the same time, he would be in.

We find the rule sensible. A course that drops gives you minutes that do not come from your legs alone, and the rule works against the easy downhill shortcut, which is what it is meant to do. What we did not find is how the BAA measures net downhill, and that is a fair question to ask. Marathon Handbook also says the BAA may still revise the rules before registration opens, so check the site before you pay.

Five steps before you sign up

First, work out your age group on race day, not today. Second, take your standard from the official BAA table and subtract 5:17: that is your limit for direct entry. Third, if your time comes from a course with a downhill, check its net downhill before you count it. Fourth, if you are above the limit, keep an eye on the draw and on other qualifying marathons in 2027. Fifth, compare dates on the 2027 calendar and read our guide to getting into sold-out 2027 marathons.

And you? Have you tried to get in with a qualifying time, or thought about the downhill shortcut? Does a 5:17 cutoff look fair, or does it shut the door? Tell us in the comments which marathon you are aiming for, and the time you need to get in.
