The GBP Trail Series will help keep you outdoors and active during the winter months while exposing you to some of the most beautiful (and runnable) trails in New Mexico. Races are held every third Saturday for the months of December through February with a post series social/celebration after the February race.

There is also a noncompetitive virtual option if you still want to get out but not in the crowds. The virtual option does not require you to run/hike the course at the preserve, just complete the distance to earn you a finishers award.

One of the greatest benefits of participating in this event (other than keeping yourself fit) is that your entry fee is essentially a donation to Commonweal Conservancy who has protected and continues to steward the over 41 miles of trails and 10,000 acres of land in the Galisteo Basin Preserve that we all enjoy. That is right, 100% of the profits go to Commonweal Conservancy and the series has raised $50,946.97.

For full race details, past results, etc, please visit the race website (this is just a registration page).

We want to extend our sincere gratitude to everyone who has participated in and supported the Doggie Division over the years. Your enthusiasm and love for the trails have truly made this event special.

Unfortunately, due to liability insurance constraints, we are unable to continue offering the Doggie Division moving forward. This was not an easy decision, as we know how much our participants and their four-legged friends have enjoyed this aspect of the series. However, ensuring the safety and well-being of all involved remains our top priority.

We appreciate your understanding and continued support of the GBP Winter Trail Series. While we will miss seeing our furry companions on the course, we look forward to welcoming you to another great season of racing!
