Come to beautiful Sonoma Valley for Nav-X's second event of 2024. A variety of terrain will be on hand from rolling open oak-covered hills to Redwood forests. Unlike most of our courses, the start and finish will be in the middle of the map on the road through Sonoma Developmental Center with Jack London State Park to the west and Sonoma Valley Regional Park to the northeast. The 2 and 4 hour courses will be GPS based, using the app "MapRun" for timing on your own schedule. The competitive window for this event is April 1- May 31, 2024. Results during this time period will be included in the official results and accrue Nav-X Challenge series points but the course will still be available on MapRun until Dec 31, 2024. Upon registration, you will receive (1) registration confirmation, (2) within 24 hours, a separate email with links to map documents.
