From about 25 years ago near the end of the Jasper to Calgary non-stop ride we did. 420 km in 19.5 hours. Not quite the pace they do on the tour. We averaged 21.5 km/h. The tour averages a bit over 50 km/hr!
The route is below. One of the most scenic roads in the world, through the Icefields Parkway. We rode it at night and it was unforgettable!
