JACK'S STORY


The Smile Like Jack Memorial Fund was established in memory of Jack William O’Brien, a loving son and brother, caring friend, and hard working young man that touched the lives of many with his contagious smile. Jack tragically passed away in a snowmobile accident on March 3rd, 2022. In his 20 short years, he had accomplished many things and leaves behind a legacy that is in a caliber of its own. Jack lived life to the fullest. He was always working exceptionally hard to accomplish his set of goals while also living the outdoorsman lifestyle: fishing, hunting, and riding. Our goal is that the Smile Like Jack Memorial Fund will bring other individuals (with similar passions) the opportunity to live their legacy just as Jack would - working immensely hard in the trades and living life to the fullest in the great outdoors.

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 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.
