It's the crawl seen around the world.
Micah Herndon, former Marine, sought out to run the Boston Marathon in honor of his fallen Marines who died in an IED blast in 2010 - he miraculously survived. Right near the end of it, his legs gave out on him due to leg cramps. But that didn't stop him. Micah pushed through to the very end CRAWLING.
As he crawled to the line, he repeated their names to give him the will to finish: Juarez, Ballard, Hamer.
Next time I want to complain about working out and being tired, I'll think of this man.
