Boston qualifiers by state

Common questions

What is the best marathon to qualify for Boston in Colorado?

By share of finishers who ran a qualifying time, The Colorado Marathon in Fort Collins: 7.5% of its finishers over the last 2 years ran under the 2027 Boston standard for their age and gender. Next is The Long View Marathon at 6.9%.

How is this list worked out?

For each marathon we take its last three years of results and count the finishers whose time beats the 2027 Boston standard for their age and gender on race day. Races need 200 counted finishers. A high share means a fast course, good weather, a field of runners chasing a qualifier, or all three.

Does every race on this list count for Boston?

Boston accepts times from courses certified by USATF, AIMS or a national governing body. From 2027, courses with a net drop of 1,500 ft or more have 5 or 10 minutes added to your time, and drops of 6,000 ft don't count. Check a race's certification and elevation before you enter.

Is a qualifying time enough to get into Boston?

No: it lets you apply, and the fastest qualifiers relative to their standard get in. Accepted runners needed to be 5:17 under their standard for 2027, and 4:34 to 6:51 in the years before.
