Boston Marathon - Episode Guide

USN's exclusive national TV coverage of the world's oldest annual marathon will showcase an expanded field of 36,000 runners tackling the historic 26.2-mile course, including many of the sport's elite marathoners and wheelchair racers.

The 120th Boston Marathon takes over the streets of greater Boston on Monday, and the runner to beat in the men's race is two-time champion and 2015 winner Lelisa Desisa. Desisa, from Ethiopia, has won two of the last three Boston Marathons. Caroline Rotich of Kenya is back to defend her 2015 title. She is regarded as more of a contender than a favorite to win and repeat. About 30,000 runners will take to the 26.2 mile course that ends with a straightaway down Boylston Street in downtown Boston.

The 2022 Boston Marathon field, which marks the 50th anniversary of the first official women's race in 1972, is expected to be highlighted by Tokyo Olympic marathon gold medalist Peres Jepchirchir of Kenya, who is making her Boston Marathon debut, and Tokyo Olympic Bronze Medalist Molly Seidel of the United States. The women's field is also expected to feature former winners American Des Linden (2018) and Edna Kiplagat (2017) of Kenya, as well as Kenyan Joyciline Jepkosgei.

The men's field is expected to be headlined by seven of the past eight Boston Marathon winners, including reigning champion Benson Kipruto of Kenya, Kenya's Lawrence Cherono (2019), Japan's Yuki Kawauchi (2018), Kenya's Geoffrey Kirui (2017), and Ethiopia's Lemi Berhanu (2016) and Lelisa Desisa (2015 and 2013). Americans in the men's field are expected to include Colin Bennie, who finished seventh in last year's Boston Marathon, Tokyo Olympian Jake Riley, Rio Olympian Jared Ward and Scott Fauble.

This year's race is particularly significant as it commemorates the 10th anniversary of the tragic events surrounding the 2013 Boston Marathon, with the anniversary to be recognized by race organizers.

In addition, one of the most popular athletes ever to play in Boston, three-time World Series champion and Red Sox legend David Ortiz, will serve as the race's Grand Marshal.
