On January 28, 2013, Luc, a United States Air Force pilot was on a training mission over the Adriatic Sea off the coast of Italy. During the sortie, Luc was forced to eject from his F-16 and did not survive the ejection. Luc is survived by family and friends who continue his Legacy through the Major Lucas Gruenther Legacy Foundation.
Major Lucas Gruenther was an incredible human being. He was an outstanding F-16 fighter pilot, community role model, and a true humanitarian. He lived his life to the fullest and never took a single day for granted. Luc is remembered for the way he treated people with wisdom and kindness and was a genuine human being who made a tremendous positive impact.
All proceeds from this race go to the Major Lucas Gruenther Legacy Foundation, an IRS-approved 501(c)(3) non-profit organization. The purpose of the Major Lucas Gruenther Legacy Foundation is to bestow scholarships to Americans for the advancement of educational goals and self development.

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 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.
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.
