We're excited to offer 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.
