Conceivably these routes could be traveled on foot, by horse, car, motorcycle, or perhaps even a wheelchair. The routes in the book are intended for folks on bicycles. Cycling is a patently dangerous activity and, by extension, so would be riding these routes be patently dangerous. The same is true, by degrees, for anyone traveling these routes, regardless of conveyance. These routes were planned taking into account the resources en route as they exist now, not what might be planned for the future. Hopefully, with time, accommodations for cyclists will be improved. Those accommodations will certainly, over time, require the routes to be tweaked. Hence, expect new editions of this guidebook from time to time.
Along the way there are 0 big boxes, 1 McDonald's, less than a dozen small strip malls, 39 small towns, 4 cities, 11 county seats, 26 county and municipal parks, 6 state parks, 1 national monument, 206 points of interest, 100's of convenience stores and 91 recommended small businesses.
The Left Wing Route is 320 miles. The Right Wing Route is 330 miles. The routes as presented in the book are each divided into 6 days of riding. For each route there is the opportunity to camp the first two nights out. The third night out is in a bed with available laundry. The fourth and fifth nights are camping out again. Of course the last night is in a bed in Savannah. Each day's ride is about 60 miles; 6 hours per day in the saddle, more or less. This leaves time for nice breaks and some sight seeing. The detailed cue sheet in the book explains many points of interest along the ride.
For both routes the first couple of days are through the rolling hills (100-150' tall) of the piedmont. The third day of each route is the big day, riding through the fall line hills (200-300' tall) of Georgia. the next two days are very gentle rollers and finally the last day is dead flat as you ride into Savannah. The prevailing wind is likely to be at your back for most of the trip. Predictably, the fall and spring are the best times to take this trip.
Some parts of this ride are quite remote and the bike shops en route can be counted on one hand. It's important service your bike before starting the trip, bring plenty of contingency parts (spare cleats, screws, spokes, tire) and know how to work on your bike. AT&T phone service is non-existent on days 4 & 5 of both routes. The Atlanta to Savannah book includes bike shop locations and phone numbers.
