Video highlights.

Tigist Tufa was a 2:40 marathoner 2 years ago. Now she's London champ.

This one was packed with drama as with 5 miles to go, it was down to the Big Three of Kipchoge, Kipsang and WR holder Dennis Kimetto plus '14 runner-up Stanley Biwott. After a 4:33 25th mile, it was Kipchoge vs. Kipsang. Kipsang finally broke with 800 to go and lost by 5 seconds.

Former champs Mary Keitany, Priscah Jeptoo and Edna Kiplagat and HM WR holder Florence Kiplagat take on Dubai champ Aselefech Mergia and 2014 World #1, Tirfi Tsegaye.

This race is LOADED. The winners of last fall's three major marathons -- world record holder Dennis Kimetto (Berlin), Eliud Kipchoge (Chicago) and Wilson Kipsang (NYC) will all be in London, as there are a total of four sub-2:04 men and eight sub-2:05 men in the field (both the most ever in one race). You know a race is historically great if a pair of 2:03 guys (Geoffrey and Emmanuel Mutai) aren't even headliners.

2013 champ Priscah Jeptoo and world half marathon record holder Florence Kiplagat join Edna Kiplagat and Keitany to form what race organizers have dubbed "the Fantastic Four." NYC runner-up Jemima Sumgong and Berlin runner-up Feyse Tadesse should also contend as part of a field that includes six women who have broken 2:21. This will also be the final marathon for British legend Paula Radcliffe.

We discuss the return of Priscah Jeptoo, wonder how fast the women could go and say goodbye to Paula Radcliffe.

We share you the wisdom we got this morning from talking to the greatest marathoner on planet earth, Wilson Kipsang, and long-time London Marathon guru Dave Bedford.
