In 2012, the ERS was founded with the intent on creating an event production brand in the trail running category. Since we started this journey the ERS has not only created that trail running brand, but we have built two great communities of support in Colorado and Southern California (San Diego).
Today, with a total of 11 events combined in the 2 regions, the ERS hosts more than 7000 beginner, intermediate, and experienced trail runners each year.
Whether you are looking for a stroll along the water, some scenic single track, or a challenging hill/ mountain course, the ERS prides itself on offering the best trail race experience and atmosphere in the industry.
Every event within the ERS offers multiple race distance options, great course support, kid's races, and finish line festivals that the entire family can enjoy with music, food, games, raffle, and plenty of beer (for those over 21 years, of course)
The Need to Knows
All race courses are subject to change at any time leading up to the race date due to circumstances beyond our control. This also applies to race dates, race times, and trails used.
Although we would like to get race courses to their exact and respectful distances, sometimes this may not be possible, and courses may measure longer or shorter than indicated. GPS between products will also always vary.
Aid Stations will include first aid, water, electrolyte, and nutrition
It is the responsibility of the runner to know the course. We mark the courses to the best of our ability with directional signs, mile markers, flour, and volunteers. We are not responsible for course sabotage and non-race personnel misdirecting runners, nor is the ERS responsible for any runner deciding to follow other runners in the wrong direction. If and when race courses are changed, we will post updated course maps online and onsite race morning.
