We're a volunteer-based, nonprofit running club that loves to have fun. We support our diverse running community through training, races, social engagement, and outreach. We foster camaraderie, collaboration, and empowerment within the club and the community.

Whether you're a seasoned marathoner or just starting out, we have a place for you at LMJS. We host regular social runs, trail runs, and training programs for all levels of runners. We also have a race team that is registered with the US Track and Field association.

But LMJS is more than just a running club. We're a community. We love to get together and socialize after runs, and we're always looking for new ways to give back to the community.

So if you're looking for a friendly and fun running club, LMJS is the place for you! Come join us for a run today!
