C4 5K Run to Defeat Colorectal Cancer

The California Colorectal Cancer Coalition (C4) is a nonprofit organization made up of a diverse group of dedicated individuals from throughout California whose mission is to save lives and reduce suffering from colorectal cancer in all Californians.

Funds raised through the “Screen Your Gut - Save Your Butt” run will be used for the C4 Community Grants Program that aims to increase screening to prevent colorectal cancer development and detect existing cancers earlier when the outcomes are more favorable for patients.


What a great day for a race! Thank you to all who turned out today. We hope you enjoyed yourselves.

Click here to access the photos taken at the Screen Your Gut - Save Your Butt 5k challenge. The image quality is likely less than ideal but hopefully provide a fun glimpse of the day's events.

Our event photographer was a no-show so these photos are all we have from the event. We already have a new photographer ready for next year so this won't happen again.

TEAMS Update!

Update: March 2

Wow! We are up to 19 teams for the event! Thank you to all for working so hard to make this a successful event. The organizing committee feels particularly inspired by those generously supporting family/friends/colleagues who are dealing with colorectal cancer and its after effects. We look forward to seeing you all on March 4.

Team MARLA and SCRIPPS Hot Butt Stuffers are making steady progress in overtaking the lead teams in fundraising efforts.

Go Team MARLA and Scripps Hot Butt Stuffers!

Thank you to all donors for all the teams - your generosity is a beautiful thing!

Current team with the most members: UCSD GI Polyp Punchers - 68 team members!

ATTENTION: 5K SYGSYB Participants - Information for Saturday's race

Many participants have had other people enter their registration details and certain data might be either missing or inaccurate in our database as a consequence (examples: T-shirt size, birthday, gender identity, incorrect name).

If you are planning on competing for race-day event medals by age and gender, please plan to show up a little early to make sure your race details are accurate (including name). 

We hope to have enough T-shirts in various sizes to cover all participants.

Pre-event registration closes at 5pm on Thursday, March 2 so the timing company can generate bibs. 

Late registration (and changes to existing registrations) will open again on March 4 at 6:30 am.

The 5k is the first race to start and will be launched at 8am.

See you on Saturday!
