The sweep was unprecedented in the history of the race, which features three-person teams that are scored cross-country style on a four-lap criterium course. Runners compete for both individual and team prize money. Fifteen men's teams and 11 women's teams competed Monday for the $108,000 purse.
South Africa's Colleen De Reuck was fourth in 33:53, eight seconds ahead of Kenyan Jane Omoro, the 1998 Bolder Boulder champ.
In the men's race, 10K world-record holder Joseph Kimani of Kenya won in 28:55, ahead of countryman Dominic Kirui (29:52) and Silvio Guerra of Ecuador (29:54). Kenya's Stephen Kiogara was fourth and David Galindo of Mexico fifth.
Kimani's nearly-one-minute margin of victory was the largest in race history, topping a record set back in 1979 at the first Bolder Boulder, when Ric Rojas defeated Frank Shorter by 28 seconds.
Kenya's 1-2-4 finish gave the Kenyans an easy victory in the team competition, followed by Mexico.
All of the races were run under very hot conditions that reached 91 degrees by the time the men went off just past noon.
"This was a tough course and tough weather," winner Kimani said. "We are human beings so of course we feel the heat."
The U.S. men's team, led by top finisher Jeff Simonich (36th), placed 14th out of the 14 teams that scored. Albuquerque residents Simon Guiterrez (39th) and Sean Tynan (42nd) were the other two members of the U.S. team.
The United States women's squad of Kristen Coogan (26th, 37:47), Carol Zajac-Tynan (27th, 37:50) and Maria Trujillo de Rios (30th, 38:32) placed 11th out of 11 women's teams.
A record 40,462 runners and walkers participated in the early-morning citizens' race. Fourteen people were sent to the hospital because of the heat.
