2026 Full Moon Challenge 12K and 12M

Join our Facebook community of almost 25,000 members HERE!

It’s that time again — the moon is calling! 🌙 Join us for our seventh annual Full Moon Challenge, a year-long celebration of determination, reflection, and light.

In 2026, there will be twelve full moons, and we’re challenging you to honor each one by running or walking 12 kilometers or 12 miles between January 1 and December 31, 2026. Complete it all at once, spread it throughout the year, or even dedicate a little distance to each full moon — the choice is yours!

This year’s medal is something truly special. It’s 5 inches wide, crafted from wood, and laser-engraved right in our garage — made with love, care, and a touch of moonlight magic. 🛠️🌕 Each one is unique, just like your journey.

• Distance Options: 12 kilometers or 12 miles
• Dates: Complete anytime between January 1 and December 31, 2026
• How to Participate: Run or walk at your own pace, in your own space
• Registration Fee: $25 (includes medal, bib, and charity donation)
• Beneficiary: At least 15% of every registration will be donated to Soles4Souls, helping provide shoes and hope to those in need across the world.

This isn’t just a race — it’s a journey through the year, guided by the glow of every full moon. Whether you’re running solo or with friends and family, the Full Moon Challenge reminds us to slow down, look up, and stay connected — to each other and to something greater.

Join us for a tradition that blends heart, craftsmanship, and community.

👉 Sign up today and claim your hand-crafted piece of lunar history before it’s gone!

What is a Virtual Race?

A virtual race is a race that can be run (or walked) from any location you choose. You can run, jog, or walk on the road, on the trail, on the treadmill, at the gym or on the track (or even at another race). You get to run your own race, at your own pace, and time it yourself. Running and walking on your own, or with friends! And your medal will be shipped directly to you. Complete a virtual 5Ks, 10K, half marathon and more!

Each race benefits a difference charity

For each of our virtual races, we choose a charity to donate a portion of each registration to. We’ve already raised more than $1,00,000 for charities from our many different virtual races! Our goal is to continue to help different charities around the world.
