Routes are subject to change. Stay Updated! Check our website regularly for the most current route information.

We're excited to offer 5K and bike route maps on two platforms for your convenience. While these tools are useful, they're not perfect. Differences in route measurements and occasional navigation quirks are due to the unique algorithms each platform uses. Expect minor discrepancies and navigation anomalies between platforms.

We highly recommend riders use RideWithGPS for the most accurate guidance. Turn by turn route sheets will also be provided at packet pickup. The Anti-Cancer Challenge road bike routes are rules-of-the-road rides. For the road bike routes, Class 1 and 2 e-bikes are permitted, while Class 3 e-bikes are not allowed.

The mountain bike ride has a strict no e-bike policy for all classes.
