Come run Castle Rock’s best trail race at the beautiful Phillip S Miller Park! The event will offer six races: a 50k ultramarathon, a marathon, a half marathon, a 10K, a 5K and a family adventure race. The event will highlight the soft surface trails that are a part of the town’s largest ever park project. The race will begin near Castle Rock’s state-of-the-art Miller Athletic Complex, a beautiful $30 million venue. The race course will showcase the trails in Phillip S Miller Park and the adjacent Ridgeline Open Space. Don’t forget to take in the impressive views of the surrounding buttes and the scenic views of Castle Rock as the trail twists and winds over the flowing race course. If you have any energy left after your race, you can climb Challenge Hill, a 200-step staircase on the hillside near the finish line.
All participants in the trail races will receive a custom technical shirt in gender specific sizing.
All finishers will get a custom made finisher medal
Music at the start/finish will create a party-like atmosphere
Professional chip timing with a disposable bib chip (Adventure run is untimed)
Fully supported course with up to 11 aid stations in the 50K
Live band on the amphitheater stage
The Miller Activity Complex will be available for athletes and their friends and families for a reduced fee of $4 on race day, so that runners can shower if needed after the race or if support crews want to rest indoors.
