Athletes may have just run the Boston Marathon less than a month ago, but it's already time to register for the next one.
Registration opened for the 2022 race, the 126th running of the Boston Marathon, on Monday, and it will be open through 5 p.m. Friday, the Boston Athletic Association announced.
This year's marathon was run in October for the first time -- moved because of the coronavirus pandemic -- and with a smaller field of 20,000 people.
