Last year a 40-year old man took top US honors in NY. Might a 43-year old running the first marathon of his life do it in 2018? That would be crazy. *MB: And the top American man in New York City will be? Read this and then give us your picks

We give you all you need to know on all the Americans not named Galen Rupp.

The Big 3 Eliud Kipchoge, Wilson Kipsang and Kenenisa Bekele are chasing the world record in Berlin on Sunday.

You'd better be tough (and talented) if you want to make the 2017 World XC team as the conditions are going to be difficult and the field is stacked with 8 of the top 9 from the Olympic 10,000 Trials. Derrick -- and almost everyone else -- missed out on last year's race, but he's back after three-peating from 2013 through 2015 but he'll have his hands full with the Kenyan-born talent in Scott Simmons group that is taking America by storm.

Also included: Meb Keflezighi (who is not running NYC) discussing his recent problems throwing up in races.

With only four men in the field who have broken 2:10 in the last three years, it's not totally crazy to think an American could win NYC on Sunday, particularly since Dathan Ritzenhein has had a great buildup.

Huddle and Conley will make their marathon debuts as they compete with Kellyn Taylor, Sara Hall and Annie Bersagel while Ritz will line up alongside Ryan Vail and Matt Llano.

Meb, Ritz and Rupp will get plenty of attention this week, so we wanted to start our previews by focusing on the men who have a shot at the Olympic team if any of the Big 3 falter. In 2012, we only had a list of 6 outside of the eventual top 4. This year, the list is 20 deep.

If Huddle and Rupp come through as favorites, the drama will still be big as one of the following three on the women's side - Shalane Flanagan, Emily Sisson and Emily Infeld - and one of the following three on the men's side - Ben True, Hassan Mead and Diego Estrada (plus Chris Derrick) - will go home devastated.

Track fans, this one is loaded with former NCAA stars. That's the good news. The bad news is you gotta choose, this or Mayweather - Pacquiao. More bad news, HSer Grant Fisher might go sub-4 but it won't count - unless Stanford changes from a 1,500 to a mile in the next 24 hours.

At the "Miracle on Dirt," the USA walked away with a silver 2 years ago. They are back at World XC trying to get on the podium. We break down their chances.

Chris Derrick 3 peated as USA Champion in dominating fashion as Bobby Curtis was 2nd and Dathan Ritzenhein 3rd. Ben True, the guy who tried to stay with Derrick the longest, faded to 11th.

8 years ago, with World XC spots on the line, the action in Boulder was legendary as all of the Colorado greats - Culpepper, Goucher, Torres and Ritz - battled. What's in store in 2015? Chris Derrick goes for the three-peat but he'll have plenty of competition in the form of Ben True, Dathan Ritzenhein, Maksim Korolev, Ryan Vail and Garrett Heath.

With wins in London and NY, no one was as good as Wilson Kipsang. But where do we rank Kenenisa Bekele, Meb and others?

Boston champ Meb Keflezighi is the big American name in New York and he'll be looking to keep the momentum going after his unbelievable win in Boston. Ryan Vail (2:10:57 pb) and Nick Arciniaga (2:11:30 pb) will be looking to battle Meb for top American honors alongside debutants Luke Puskedra and Aron Rono.

Other top Americans announced include Ryan Vail, Nick Arciniaga, Luke Puskedra in his debut, and Deena Kastor.
