The 7/20 Foundation is proud to present the 5th annual Hero’s Journey 5k Run/Walk. This race makes its way through Aurora's City Center and the High Line canal trail with a start and finish in the 7/20 Memorial Reflection Garden. For those over 21, this race includes admission into the 7/20 Foundation's annual beer festival.
The Hero's Journey represents any person who faces a challenge, encounters struggles to overcome it, and returns home a Hero. We hope this 5k is a transformative experience as you run/walk together; whether you are a veteran runner or this is your first 5k. We chose to start the run across from the theater and end in the 7/20 Memorial Reflection Garden as your return home/finish line to honor the journey from tragedy to hope. It is the perfect place for each of us to honor and celebrate our collective accomplishment as well as our heroes from the July 20, 2012 tragedy.
Proceeds raised through the event will go toward the Zack Golditch Opportunity Scholarship.

The Crooked Gravel takes a few cues from an exploratory event the legendary Ron Kiefel put together a decade ago called Crooked Roubaix. Back before gravel bikes were really a thing, Kiefel and some friends set out on a 95-mile dirt-road adventure from Winter Park up into the high mountains on road bikes.
Fast forward to 2026 and gravel bikes are a thing. Our routes take in the very best of Grand County gravel, with long, winding climbs up through aspen and pine forests, wide open descents under the massive Colorado sky and some secret tracks never before explored in a cycling event. Click here for complete information.
In addition to a great experience on your bike, each participant will receive:
Commemorative t-shirt
Refreshments and support throughout the race
Post-race meal
A chance to win valuable prizes
Bike number with timing chip
Opportunity to compete for the podium and purse (long course only)
Age Group Awards
Course Overview and Finish Details
Both courses will begin with a police-led neutral rollout for approximately 4 miles. Shortly after, the routes will split:
-The 25-mile course takes riders on a scenic and enjoyable loop, with the timed section ending around mile 23.
-The 67-mile long course follows a challenging lollipop-shaped route, with the timed section concluding at approximately mile 62.5.
While your official time stops there, your ride isn’t truly complete until you roll back into town and cross under the finish line arch—where you’ll be greeted with free food, cold beer, and live music.
Please remember to follow all rules of the road, especially during the untimed section as you return to town.
We can’t wait to cheer you across the finish!
HOW REGISTRATION WORKS
The event is comprised of 24, 1-hour games in a row and is open to men's and women's teams of all ages and abilities. Every team that registers plays in at least one, 1-hour game and will be matched with an opposing team of similar age and abilities
If you register as a dual-slot, your team will have the entire hour with no opposing team schedule, and choose how you wish to play for that hour.

Have you been dreaming of running the Boston Marathon? Need to shave a few minutes off your qualifying time? Or maybe you're just looking for the perfect course to set a new PR? Whether Boston is your goal or not, the Bound for Boston Marathon & Half Marathon is for you.
We're racing around Northfield High School, and the course is a 1-mile super flat & super fast loop! The Full Marathon is USATF Certified making it a Boston Qualifier!
This event is uniquely designed for serious runners. We will have water and an electrolyte drink at the aid table. Participants are welcome to bring their own personalized aid to place on the aid tables, allowing you to grab exactly what you need each time you pass. Many runners even bring a cheer crew to help hand out fuel and keep the motivation high throughout the race.
To maintain the best possible experience, this is intentionally a small, focused event, capped at just 75 participants.
We will have a great race shirt and finisher medals for all participants. Awards for both distances are in the usual 5-year age groups.
Fast course, flexible support, and a chance to chase your goals—this is the race that lets you run your perfect day.
By design this will be a smaller event, focused on getting you your fastest time.

Founded in 1979, the Eldorado Run for the Cure is the longest operating charitable footrace in the State of Colorado. All proceeds from the annual four-mile run benefit the Colorado Cancer Foundation's life saving work, from funding oncology research at the University of Colorado's (CU) Division of Medical Oncology to aiding patients at the CU Hospital in Aurora, CO.
Each year, the run has developed and grown, and in 2023 a new course was introduced, routing participants along the scenic South Boulder Creek, which winds through the high cliff walls of historic Eldorado Canyon.
