• a day-long party 50K Relay- 5 10K loops let you share your vert with friends (relay teams are 2-5 people)
• a truly intrepid 50K - 5 10K loops covering almost 5000ft of vert. gain that will lead you on a journey from confidence to self-doubt and back again, earning you bragging rights as a finisher of the only 50K race in North Park.

We at GCXC love dogs and many of our staff have them.  They are a wonderful addition to any family.   However, for safety and insurance reasons, we do not allow them at our events.  Please come to our races and have a blast with your family, friends and fellow runners but we kindly ask you to leave your dogs at home.  

SERVICE ANIMALS:  If you will be accompanied by a service animal, please contact the race director before the event so that we may make the appropriate accommodations for you.

Thank you for your understanding and cooperation.

In an effort to leave a smaller carbon footprint, GCXC has eliminated the use of single-use plastic bottles at its events.  Post-race, we will have coolers with water and Gatorade along with paper cups for all participants to rehydrate.   Please feel free to bring your own reusable bottles or flasks to fill up at the conclusion of the event.

These results are accurate as of June 2, 2025 at 8:30pm. Thank you for your patience as we get the first round of results correct - many of the original names imported incorrectly.
