It’s that time of year again, when spring is in the air, and the city is abuzz with thousands of runners pounding the 26.2 miles of pavement between Hopkinton and Copley Square — it’s Boston Marathon time.

For those looking to cheer on loved ones, or just hoping to catch a glimpse of the 121st marathon, here’s what you need to know:

What time does it start?

Start times for the 2017 marathon begin at 8:50 a.m. and go until about 11:30 a.m., with runners taking off in a predetermined order, depending on their division.

Getting around

The easiest method to get around the city is the T. The city is encouraging people to use public transportation, though you’ll want to keep an eye on station closures: The Copley station will be closed all day, and the South Street, Kent Street, and St. Mary’s Street stops on the Green Line will be closed from 10 a.m. until about 6 p.m.

Planning on taking the T? Here’s a viewing map to help you follow along.

But what if I’d rather drive?

The good news? Parking meters are free. The bad news? After 8 a.m., all streets east of Massachusetts Avenue in Back Bay (as well as Massachusetts Turnpike Exit 22) will close. And it’s only going to get worse from there, with all streets west of Massachusetts Avenue closing at 9 a.m.

The city of Boston has posted a full list of street closures for the marathon. Drivers should expect traffic anywhere near the race’s route, particularly in the Boston area.

What should I leave at home?

You might want to leave the masks and props at home. Security will be tight this year, and authorities have added trucks and drones for added protection. The BAA released a comprehensive list of banned items for spectators, including weapons, backpacks, suitcases, coolers, costumes, masks, and props. Check here for a full list of items to ditch to make sure you won’t be turned away.

What will the weather be like?

A little chilly to begin, but the day is going to heat up into the 70s. Temperatures will start at about 62 degrees for the race, and then increase to about 70 by noon to 1 p.m., according to meteorologist Dave Epstein.
