With only a few strides remaining in the American Discovery Trail Half Marathon, Connilee Walter took a look at her watch.
It told her to finish fast.
Walter put the hammer down and crossed the finish line in America the Beautiful Park with a new course record of 1 hour, 27 minutes, 38 seconds.
"I gave it everything I had," she said.
The old record of 1:28:11 was set by Ashlee Nelson of Colorado Springs in 2008. She was 27 at the time.
In the men's half, Ben Klungtvedt, 26, of Colorado Springs, took the win in 1:18:03.
Martin Mudry, 24, of Colorado Springs, won the marathon, setting an age-group (20-24) record of 2:32:53.
In the women's marathon, Sharon Howard, 27, of Aurora, won with a 3:01:01.
