Set a personal record (PR) at the 2027 Spring Blast 5K, 10K, and Half Marathon on a flat course at an elevation of 3,671 feet. All runners and walkers are encouraged to participate in these races. Choose the distance best for you on these out-and-back courses run on paved roads. Roswell’s average temperatures in early March range from the mid-thirties to the low seventies. All three races have the same start and finish points. The courses are located on the Eastern New Mexico University-Roswell campus and around the Roswell Air Center. There is easy access and plenty of available free parking. Race proceeds will be donated to the ENMU-Roswell Foundation for student scholarships. We strive to provide safe, well-supported races. EMS will be present along this well-marked course with aid stations approximately every two miles. The course will remain open for 4 hours.

About This Sport
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 half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
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.
