Hit forty and your knees begin to ache. It's like they want to give you an excuse to grow fat and sedentary. What do you do? Buy or rent a bike. Athens, Georgia has the best cycling in the Southeast—just ask Bicycling Magazine, which recently anointed our Apple Vally Loop the best ride in Georgia. Groups-about and rides are scheduled daily for experts and beginners alike. Google "Nitty Gritty Bike Bank" or "Athens Georgia Bicycling Club" and check out the group ride calendars. Pick from a century (metric or miles) and hit the road. The hills can challenge, but the scenery will make the miles flow under your wheels.
When you are ready to buy, visit the HUB. There are many excellent bike shops in Athens, but the HUB is home. Hit the road and burn some calories.
