Six Gap Century 100 mile and Three Gap 50 mile bike ride through the mountains. Georgia's largest mountain ride is held annually the last Sunday in September. Six Gap Century:

This ultra-challenging route takes you up down six of the steepest climbs in the North Georgia Mountains. Test your stamina with more than 10,700 feet of vertical climbing over the 100-mile course. Elevations for the six gaps in this ride range from 2,949 feet to 3,490 feet.

The toughest climb, Hogpen Gap, tests even the toughest riders, averaging a 7% grade for seven miles, with sections as steep as 15%. Three Gap Fifty: This alternative route offers half the gaps and half the distance, but is nevertheless a demanding and challenging course. Elevations for the mountains on this ride range from 3,109 feet to 3,280 feet.
