Despite stopping twice out on the course due to stomach pain, Olaru never faded or lost her lead. She crossed the finish line in 2:50:08. Olaru placed second at last year's Rock 'n' Roll Denver Half Marathon.
The Romanian born Olaru finished 13th in the marathon at the 2004 Olympics. She recently got her U.S. Citizenship but it wasn't in time to run the U.S. Olympic Marathon Trials last January. At 41, Olaru's chances of making the U.S. team in 2016 are slim.
Amy Lane, also of Colorado, placed second in 3:09:42. Cassandra Allred of Menlo Park, Calif., was third in 3:11:34.
On the men's side Adam Roach of Pacific Grove, Calif., took the top spot in 2:32:25, followed by Chris Mocko of San Francisco in 2:34:11 and Jesus Campos of King City, Calif., in 2:37:08.
The top male from Colorado was Ryan Handzo of Boulder who finished in 3:21:12. Greg Roscow was the second Colorado male finisher in 3:23:39 and Seth Roland was the third Colorado finisher in 3:25:11. The third Colorado woman behind Olaru and Lane was Carolyn Chase of Littleton in 3:34:26.
Just over 3,300 runners participated in the full marathon. The event drew nearly 11,000 runners between all of the races, which included a 21-mile run, a 10.6-miler, a 9-miler and a 5k.
