Fly into Calgary, rent a car, and drop it off in Jasper. Ride down the Icefields Parkway before starting the GDT in Banff. Finish the ride in Breckenridge, CO. At that point I’m planning on getting a ride to Denver and a flight home. Daily mileage depends on availability of campsites or lodging in town. I’m a solo rider who thinks a ride is always better with company.
