Aaron Donovan loves when friends jump into the Marathon to run for awhile with their friends.

Paul Kelleher captures the women leaders at mile 17 (he took more Marathon photos, too).

This little kid just stood in Washington Square with his hand out today. It was amazing how many runners gave him a hand slap.

I'm watching the Marathon live. Is it just me, or does Bob Lobel also remind you of Willard Scott in "Best in Show"?

I mean, I love the guy, but he seems to be there for the celebrity factor, and he's a bit underprepared. As Biktimirova and Tuna battle it out:

Bob: "When's the last time a Russian woman won the Boston Marathon?"

Other commentator: "Last year..."

Michael Pahre discusses the oddity of Boston having two marathons this year - one Sunday for Olympic women trialists, and the normal one, on Monday.

Jim Sullivan recounts a day at the race.

Boston Police vow to crack down on drunken revelers. Are you listening, Boston College?

Why Tufts's president isn't running this year.

The year's grossest Marathon discussion.

Alicia is a librarian who is training to run in the Boston Marathon. That lets her put up the absolute best banner ever for a running librarian blog.

She's also raising money for her run for Mass. Eye and Ear. John Keith, the bloggin' broker, is also running for charity, in his case, Community Servings, which helps people with terminal diseases. Any other local bloggers running the race for a good cause?

By the time the middle-of-the-packers started hitting Washington Square in Brookline today, you could tell an awful lot of people were running on sheer willpower alone.

John Daley stationed himself at Cleveland Circle for these great shots.

Kurt in Boston posts photos of the leaders at Heartbreak Hill (more Heartbreak Hill photos).

Helga wondered why the hell one reporter was trying to interview runners at Heartbreak Hill:

... The runners he tagged seemed pretty easy going. Were they too tired to fight him? In this position, I don't know if I could handle the questioning. I'd either be rude ("Why are you talking to me? Can't you see I'm trying to run a marathon, you idiot?") or so tired that I'd lose control of myself and burst into tears. Either way, not pretty. ...

Michael Femia posts photos from Brookline. Il Filosopho also snaps Brookline pics.

Sandy posts photos from Back Bay.

Miss Von Schtoop: Running a marathon is something I have no plans to ever try.

These women cracked me up. Whenever they saw a male runner they thought was hot they'd yell "I like!" in Borat-ese:

Of course, everything could be wiped away in a Nor'easter of epic proportions (and wouldn't Harvey Leonard be ecstatic?), but just in case:

Adam Weiss podcasts from the offices of the Boston Athletic Association, all about the race, of course.

J.L. Bell sets the historical scene for the holiday, with a post on who tipped off Paul Revere and the Raiders other Patriots that the Redcoats were on the way, another post on yet more inaccuracies in Longfellow's famous poem and a calendar of events for Monday (barring torrential downpours, you'll probably find me and the kidlet at Old North Bridge in Concord).

John Keith is running in this year's Marathon and is looking for sponsors - with proceeds going to the Pine Street Inn.
