10 Unique Running Events Worth Adding to Your Race Calendar
Whether you’re searching for a fun 5K, a themed group event, or an unforgettable destination race, these creative running experiences can help make your next race weekend more exciting.
The Zombie Charge
Best for: Obstacle course fans and group runners
The Zombie Charge combines a traditional 5K with an interactive survival game. Runners wear three removable flags on their person (like flag football), and zombie participants work hard to “infect” runners by removing all three flags before they cross the finish line. Zombies are played by volunteers in professional makeup, and the 5K race with obstacles is open to anyone over 10 years old, so the whole family can enjoy running for their lives.
The Krispy Kreme Challenge
Best for: Foodies and food-themed race lovers
This legendary North Carolina race has sparked a great debate here in the Nuun offices. Half of us think that The Krispy Kreme Challenge sounds like fun, while the other half would rather watch from the sidelines. Runners complete a 5-mile course with a donut-eating checkpoint directly in the middle, where they consume a dozen donuts. Equal parts endurance event and social spectacle, it has become one of the most talked-about novelty races in the running community.
The Great Inflatable Race
Best for: Families and beginners
The Great Inflatable Race transforms a traditional 5K into a giant inflatable obstacle course filled with activities like a climbing wall, slides, and something called “The Castle of Doom.” The fun-first atmosphere makes it ideal for runners who want a less competitive race-day experience.
The Great Inflatable Race travels to different locations around the country, so check their website to find a location near you.
Bare Buns Fun Run
Best for: Runners looking for unconventional race experiences
This clothing-optional 5K has become one of the more infamous novelty running events in the US. The Bare Buns Fun Run, hosted at the Tiger Mountain Family Nudist Park, embraces humor, community, and body positivity while offering runners a completely different kind of race-day story. While the event is clothing optional (so it’s not mandatory to race in the buff), they do note that many of the participants, officials, and spectators will be au naturel. Don’t forget your sunscreen!
Underpants Run in Kona
Best for: Charity-focused runners
The Underpants Run in Kona is held in the week before the Ironman World Championship and combines costumes, community fundraising, and running culture into a memorable charity event. In its 22nd year, the Underpants Run has raised over $300,000 for local charities and continues to serve as a baffling sight to unsuspecting tourists.
Disco PBR (Paddle, Bike, Run)
Best for: Multisport athletes
Before you start practicing your keg stands, you should know that in this case the PBR in Disco PBR stands for “Paddle, Bike, Run.” This Montana-based event can be completed as an individual or in teams. With a 6K run, a 10K bike ride, and a 1K paddle board journey, it will take a well-rounded athlete to toe the line at this event.
Foam Glow 5k
Best for: Night race enthusiasts
Part race and part glow party, the Foam Glow 5K describes itself as the “craziest 5K on the planet.” Foam Glow combines music, foam stations, black lights, and colorful visuals into a high-energy running experience that prioritizes fun over finish times.
Beer and Bagel Off-Road Race
Best for: Trail runners and social runners
The quirky Beer and Bagel Off-Road Race started in Nebraska 25 years ago and is now in six different states, serving up the same strange combination of bagels, beer, and 4(ish) miles of challenging off-road running. Did we mention the homemade chili? What about the giant sasquatch? Look for both if you’re lucky enough to take part in this fun run.
Barkley Marathons
Best for: Experienced ultramarathon runners
Known as one of the hardest marathons in the world, the Barkley Marathons opens to only 40 participants each year. This annual Tennessee ultramarathon trail race has only been completed 18 times since it began in 1986. In addition to a secretive registration process and some strange in-race requirements, the course itself includes massive elevation gains and a nontrivial amount of night racing. If that’s not enough to give you pause, then you might be brave enough to give this 100-mile monster a try. Just be sure to pack some Nuun hydration support—you’re going to need it!
The Great Alaskan Running Cruise
Best for: Destination race travelers
Combining scenic travel with guided running experiences, The Great Alaskan Running Cruise allows runners to explore Alaska through organized runs, scavenger hunts, and group activities at multiple destinations throughout the cruise. This Alaskan cruise gives you nine days of R&R (relaxing and running). Some runs are long, some are short, and some are scavenger hunts! You can expect to see waterfalls, glaciers, and plenty of other people who love running as much as you do.
Hydration Tips for Unique Running Events
Whether you’re tackling an obstacle race, running a themed 5K, or preparing for an endurance challenge, proper hydration can help support performance, recovery, and overall race-day comfort. Many unique running events take place outdoors, involve long periods of activity, or include things like obstacles and travel, which can increase sweat loss and electrolyte depletion.
To help stay hydrated before, during, and after your next race, consider building hydration into your training routine:
- Hydrate consistently in the days leading up to your event.
- Bring electrolytes for races held in hot or humid weather.
- Replenish fluids after longer runs or endurance events.
- Practice your hydration strategy during training runs before race day.
