From the Promoter:
Registration is now open for this summer’s hottest hootenanny: The HARDford 50 Gravel Grinder in beautiful downtown Hartford, Tennessee. The fully-supported course is 50+ miles and 6,500 ft. of climbing through Cherokee and Pisgah National Forests. CX and MTB are both appropriate. The ride is ~75% gravel, ~10% dirt, and the remainder on pavement. Three fully stocked aid stops along the course.
