In 2010, The Endurance Race Series (ERS) was founded with the intent on creating an event production brand in the trail running category, starting with 3 events. Over the next seven years the Endurance Race Series has not only created a trail running brand for itself, but it has also helped build its own trail running community within Colorado and California (San Diego). 


Today the ERS is widely considered to be Colorado's Largest Trail Race Series, and San Diego's fastest growing trail running races. With a total of 15 events combined in the 2 regions, the ERS hosts more than 6000 beginner or experienced trail runners each year. 


Whether you are looking for a stroll along the water, some scenic single track, or a challenging hill course, the ERS prides itself on offering trail runners the BEST 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, raffles, and plenty of beer (for those over 21 years, of course). 


OUR MISSION:
It is the mission of the Endurance Race Series to provide competitive, quality events to the runners in the trail running community, while providing an entertaining, relaxing, family friendly atmosphere to those spectators and sponsors in attendance.​

Trail running races are not just for adults...  

The Endurance Race Series is excited to offer our very popular "Kids Dash" presented by the Western Dairy Association for all kids 10 years and under.  The "Kid's Dash" is available at each of our races and will normally be measured out between a quarter mile and a half mile depending on the ages of the kids that are participating. 

Kids registration is $10 and available onsite, race day only, and includes a kids medal. ​

ERS Announces New Trail Race in San Diego. San Pasqual Valley Half Marathon and 10K

The Endurance Race Series believes the finish line festival plays as big a part in the race experience as the run itself, so we always try and provide our runners and spectators with as much entertainment, food, and beer as possible at each and every race. Whether its a post-race wine tasting, Pancake Breakfast, or just good old fashioned expo with sponsor demos, music and games, our festivals are family friendly and keep the party going all morning long. 

If you are a company looking to join us as an expo vendor at any or all of our events you can find our expo application HERE, or email us and we are happy to answer any of you questions.
