About the event

🎀 Join the Fight: Breast Cancer Run! 🎀
Lace up and make a difference at our annual Breast Cancer Run! Together, we can raise awareness and funds to support those affected by breast cancer. 
Enjoy a spirited day filled with community, inspiration, and hope. Let’s unite for a cause that touches us all and run for a future without breast cancer! Sign up now and help us make a lasting impact!

Forget the massive, impersonal race-day crowds. We keep things small, personal, and local, so every run feels less like a number and more like a memory. Whether it's a 5K, 10K, half-marathon, or virtual run, you'll get the warmth of a hometown event.
 

Overview:
Spots sell out FAST! We close each wave the moment it fills. Once a wave sells out, you can grab the virtual run option or join the waitlist.

This is a smaller, private group run with a capped field per wave so it never feels crowded and you're never just a bib number.
All paces and ages welcome (under 18 with a guardian) - run it, walk it, however you like!
There's no gear, no setup, no fuss - just you, the course, and our coordinators cheering you on in a relaxed, stress-free setting.
When you sign up, you're not just registering for a race - you're getting real support toward your fitness goals, plus an invite to join one of our local run clubs to keep the momentum going.
 
Timing:
Optional! Track your own time via Strava, RunKeeper, Nike Run, or similar, then submit it through our easy online form to get posted.  Or just ask a coordinator to help time you.
No timing chips - this is about progress, not pressure.
 
What You Get (Swag Bag):
- Running T-shirt (shipped to your address - U.S. only)
- Finisher's medal
- Virtual Training Run (emailed to you a month before your run)
- Online results & certificate of completion
- Invitation to join a local running club
- NEW: Upgrade to a lightweight, moisture-wicking technical shirt for just $5 more
 
Packet Pickup?
Skip It. No lines, no hassle - your swag ships straight to your door. (Double check your full U.S. mailing address, including apartment number, when you register as your shirt is sent to this address!) Race bibs are simply handed out on race day.
 
When Will My Swag Arrive?
Your shirt will arrive at your mailing address the week of your race.
 
Signing Up Last Minute? (Within 2 Weeks of the Race)
No problem - just note that shipping may not catch up in time, so your shirt could arrive after race day. No worries, though: wear whatever you like and come run with us anyway!
 
When Will I Receive the Course Map and Details?
We'll send final participant info by the Wednesday before race day with all the details and course maps.
 
Wave Times  (Once you've registered, use your confirmation number to reserve a wave here)
Wave A: 7:30 AM
Wave B: 8:00 AM
Wave C: 8:30 AM
 
Running Late?
Jump in when you arrive - our coordinators stay on-site for 3 hours after the first wave. Times may be subject to change depending on seasons, please check your participant info email!

Virtual Run Option
Prefer to run on your own time? Our Virtual Run includes a digital training pack to keep you on track. Run it whenever, wherever, with any tracking device you like (optional) — then send your results to info@thebestraces.com to claim your medal.
