Race History

The Anchorage Running Club’s Trent Waldron Half Marathon & 10K features a scenic out-and-back course along the Chester Creek and University Trails. For runners who are younger than 23 or who moved to Anchorage after 1995, the story behind the race’s name may not be widely known.

The event honors Marcie Trent, age 77, and her son Larry Waldron, age 45, who were tragically killed by a bear while running the McHugh Creek Trail on July 2, 1995. Running with them that day was Marcie’s grandson and Larry’s nephew, Art Abe, then 14, who was able to escape and survive.

The race began the following year, in 1996, sponsored by the Anchorage Running Club, as the Marcie Trent and Larry Waldron Memorial 5K Run/Walk. In 1997, the Anchorage Running Club assumed sponsorship of the Glacier Half Marathon and renamed it the Trent Waldron Glacier Half Marathon in their honor. The event continued to evolve, and a 10K distance was added, named the Pulsator 10K after John and Marcie Trent’s running group. In 2017 the race became officially known by its present name, the Trent Waldron Half Marathon & 10K.

Marcie Trent was a remarkable runner who regularly won her age group, setting records—both locally and nationally, some of which still stand today. Larry, like his mother, was frequently among the top finishers and shared her passion for longer-distance races.

As you line up to run the Trent Waldron Half Marathon or 10K, take a moment to remember Marcie and Larry. Their legacy lives on, and in spirit, they continue to run these trails alongside you.
