Hmm ... 22 is easy, wonder if I could do 47?
ABC's ITP/OTP Ramble offers something for every road cyclist: long rolling stretches, quiet tree-lined avenues, scenery both familiar and new, and in this "City of 100 Hills", a good measure of climbing.
All mileage options -- from 22 miles up to the full century -- start/end at Atlantic Station and explore routes both new and old; you'll find yourself reaching familiar destinations by unfamiliar roads. You can read highlights of each route here
