2021 Will Be the Year of the Marathon: Here’s Why

Marathons have always been a popular challenge. But for 2021, they’ve become an especially historic event.

Depending on the marathon, “race season” usually fluctuates every year. Certain marathons always aim for spring (like the Boston and London Marathons) or even a certain date — like the NYC Marathon, held on the first Sunday of November.

But after the postponements and various race complications caused by COVID-19 over the last year, 2021 has looked very different. Namely, some — really most — of the world’s most historic marathons are happening back to back.

We’ve got everything you need to know about which marathons are happening when, which still have registration open, and why this year could be the best year ever for marathon runners.

Major Marathons in 2021

Major international marathons including the “Big 5” — Berlin, London, Tokyo, Paris, and Hong Kong — are all happening back to back within a 2-month period. And the biggest marathons in the U.S. — like the Boston, Chicago, Los Angeles, and NYC Marathons — also take place within that same timeline.

How did that happen? Well, race organizers have been making constant updates as to when they feel safe to welcome back a large field of runners in person. The Boston Marathon and London Marathon (usually held in April), and the Hong Kong marathon (usually held in early spring) were all postponed to October.

Not only is this in-person, fall marathon lineup a big deal for elite runners, but it will also be a big deal for spectators.

And the hype around this year’s massive marathon schedule — whether its back-to-back nature was on purpose or a coincidence — is big. Even brands are stepping in, kitting out marathon runners and designing marathon-themed shoes to help celebrate.

Here are the biggest marathons to watch for in 2021, in order by race date:

Editor’s note: Most of the marathons on the list above have virtual race options this year. Virtual registrations are still open.
