As one of the official world marathon majors, the event is one of the biggest of the year. The field will feature many of the best in the world on both the men and women's side.
Per the race's official website, the field assembled is one of the best in history.
On a course that has generated fast times in the past, including Paula Radcliffe's stunning world-record performance of 2:15:25 in 2003, it is possible we could see records fall.
This could turn out to be a very special day of running. Here's how you can catch the action and details about the route:
Route, Start Times and Coverage
The 26.2-mile course runs around the river Thames.
Per Simon Head of The Mirror, runners will also pass the these historic landmarks: Tower Bridge, Cleopatra's Needle, the London Eye and the Houses of Parliament.
Per Alex Wynick of The Mirror, the start times for the different divisions of competitors are as followed:
The Elite Women's race begins at 9:00 a.m. from the blue starting point on Shooter's Hill.
The Wheelchair Race starts at 9:20 a.m., also at the blue starting point.
The Elite Men's and the Athletics Championship races start at 9:45 a.m. from the blue starting point.
The mass start is at 9:45 a.m.
All of the courses join up after 2.8 miles in Woolwich.
If those stateside want to catch coverage of the event, they will have to get up pretty early or stay up very late. The BBC network will be providing full coverage of the event beginning at 3:30 a.m. ET.
Three Kenyan men highlight a strong field. Defending champion Wilson Kipsang is eyeing the repeat after taking last year's event with a time of 2:04:44.
Kipsang's countrymen will push him hard, though. The biggest threat to Kipsang's repeat will come from world-record holder Patrick Makau.
Makau set the record in the Berlin Marathon in 2011 with a time of 2:03:38. On a fast course and charged by an elite field of competition, it will be exciting to see if he can break his own record.
Last, but not necessarily least, is Geoffrey Mutai. He has run a career-best time of 2:04:15 in winning the 2012 Berlin Marathon. He will have to be at his best to compete with Makau and Kipsang.
The 2012 Olympic gold medalist and record holder Tiki Gelana is the woman to beat. The Ethiopian ran 2:23:07 in the London Olympics and showed tremendous resolve in the process.
After stumbling when she was tripped up by another runner, she injured her elbow and contemplated pulling out of the race.
Instead, she persevered and became a champion. Imagine what she'll do on a fast track—while presumably staying on her feet for the entire race.
Her main competition would have come from Kenyan Lucy Kabuu, but she has withdrawn because of a lack of conditioning.
That leaves Florence Kiplagat, another Kenyan woman, as Gelana's most formidable opponent.
The 26-year-old has won the Sapporo Half Marathon in 2011, but she's now looking to step up and knock off one of the truly elite runners in the world.
Other Notable Events and Information
Mo Farrah's Appearance
Mo Farrah is up for the London Marathon—half of it anyway. Farrah is now a national sports hero in England after capturing Olympic gold in the 5,000 and 10,000 meters at the London 2012 games.
He will run the full marathon in 2014. But his decision to run just half the distance for a handsome purse has created some controversy.
According to Anna Kessel of The Guardian, former athlete and BBC commentator Michael Johnson implied the appearance was "all about money."
Per Kessel, Farrah says he is "no money grabber" and that his purpose for the abbreviated run is to learn the sport and track before he takes it on in all its glory in 2014.
I'm not sure why taking a reported £450,000 (per Simon Hart of The Telegraph) to run half a marathon is a bad thing.
Marathons genuinely double as major charitable events, and the London Marathon is no different.
The event is sponsored by the London Marathon Charitable Trust. Per the race's official website, since the event began, £45m has gone to the London Marathon Charitable Trust.
That doesn't include the £51.8 million runners have raised for their own charities. This should be a wonderfully competitive, festive and charitable event.
