From the Organizer

Are you ready to test your limits, your strength, your tenacity and to accomplish one of the hardest races of your life. Well you have come to the right place. Dragon trails will challenge you through the trails at pearsall park. We have three races for you to choose from 

First choice and the most challenging is the Great Dragon 25k Trail race which has a 2 loop course through the front hills of the dragon trails and then you follow it to the back trails which are nicer to travel but are relenting with the heat. This course will have a waterstop every mile with water and gatorade for each runner. 

Second choice will be the Ultimate Dragon 10K which consist of almost all the same course as the 1st loop of the 25k, only difference it turns around early near the 7th waterstop. The 10k will also have tons of hills and heat for all of our contestants. Just because its a shorter race does not mean it will not challenge everything you have to finish the event. 

Third option is San Antonio's Toughest 5K with nearly 100 feet of climbing through each kilometer. This race will definitely make every other 5k you have ever run seem like a walk in the park. If you are ready to experience what true trail racing is without doing the longer distance than this will be the race for you. 

All runners will receive a specific event race medal or finisher tile, a singlet with the race logo and a taco breakfast for you to enjoy post race. This event will be officially timed by our Best race timers IAAP. We will have age group awards for all events starting 19 and under and going up to 70 plus with 10 year increments for the 1st place. We will have our amazing DJ Dragon and Announcer representing and making sure you guys have a great after race party. We will also bring back our amazing photographers from J&B Photography to capture your amazing faces through the full terrain that the dragon trails has to offer.

Race Location

About This Sport

From Endurance Grid's Founder

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

The 10K is the distance where running stops feeling like a starting point and starts feeling like a sport. Long enough to require a real training block. Short enough that race day is fully manageable for a first-timer who's put in the work.

Race day energy at a 10K is community at its best — strangers cheering you by name, people moving toward the same goal, an atmosphere that solo training can't replicate. It's fast enough that you'll spend the whole race pushing rather than managing your effort.

This is also the distance that builds the base for everything else. Most athletes who go on to run half marathons, do triathlons, or compete in HYROX started here. What you need: running shoes fitted to your stride, a training plan, and the race on your calendar. The registration is what makes the deadline real.

How long to train: 4–8 weeks for most fitness levels.

Running

From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
