How Do the Hills Impact Time?
After decades of results and tens of thousands of finisher data points, the hilly Horsetooth Half course is generally considered to run about 4 minutes slower (approximately 5%) than a flat, sea level course for those running at the front of the race.
The Horsetooth Half Marathon has been run annually since 1974; however, the course has changed a number of times due to construction on the Horsetooth Reservoir dams and, more recently, to accommodate growth in the size of the field. According to race historian and previous winner (1986), John Lonsdale, there have been at least six versions of the course over the years.
1974-1977: In the early years, the race was not much more than a hard training run among a few dozen friends, but they were the years that established the original route. It started at the intersection of LaPorte Avenue and Overland Trail. The runners went west toward the site of the CSU Foothills Campus, jumping a gate along the way. Nearing the eastern edge of Horsetooth Reservoir, the runners headed south on a singletrack trail along Dixon Canal. Jumping another gate, the runners continued south on the dirt trail toward Hughes Stadium, where they linked with County Road 42C and finished on the hills near today’s Pineridge Natural Area. The route took the runners north on County Road 23 (Centennial Drive), along the east side of Horsetooth Reservoir to Bingham Hill Road. From there, runners went over the two hills to Overland Trail, heading south to Shiloh Drive at the finish.
Nobody remembers who won that first iteration of the race, but John Lonsdale believes either Wes Crist or Ron Smith likely won it. Irish Elementary School teacher Donna Messenger and former Colorado State Marathon record holder was one of two women who ran that first race, and she is credited with being the women’s winner of the inaugural running.
1978-2006: Known locally as the “classic route,” the race started as it does today on County Road 42C adjacent to Hughes Stadium, but headed east to Overland Trail where runners ran north to Bingham Hill Road. From there, runners essentially ran the first 8 miles of today’s course in reverse heading west over Bingham Hill toward Centennial Drive before heading south on Centennial Drive back to the finish at Hughes Stadium.
1982 & 1985: In 1982 and ’85, the course was altered due to construction on the dams. The alternate course headed east on Drake Road from the stadium to Taft Hill where it turned south to 38E. From there it headed west around the southeast side of the reservoir to South Bay, where it turned around and ran back to Centennial Drive, heading north over Dixon Dam’s “Maniac Hill” to the finish at the stadium.
2001-2004: The classic route was altered due to resurfacing work that was taking place on the Centennial Road dams between 2000 and 2004. The alternate route started on the north side of the stadium and headed north on Overland Trail to US 287B where it turned west past Cache La Poudre Middle School to Vern’s, veering west on Rist Canyon Road to Bellvue. At what used to be the Bellvue Bean, the route headed south on N Co Rd 23 (Centennial Drive) for a short distance to Bingham Hill Road. It then came back east over Bingham Hill and turned back south onto Overland Trail and returned to the Stadium where it finished.
