All four winners erased the course records at Sunday's Houston Marathon and Half Marathon. Etiopians swept each of the top spots.

Race conditions were perfect, with a temperature of 52 degrees F at the start to greet a record 20,000finishers in the event’s three races.

“The 40^th anniversary is a significant milestone,” said Brant Kotch, president and race director of the Houston Marathon Committee. “When you think of how far we’ve come, from 113 runners in Memorial Park to more than 20,000 participants in three races spanning the city, anything is possible.” photos by Dustin Whitlow for UjENA FIT Club
