Greg Nance submitted the Route:

Began at Montreal Airport's (YUL) arrivals level then crossed the 520 highway onto Victoria Street before it merged into Notre Dame Street West. Lots of roadwork and construction but otherwise an easy 21.47km from outskirts into heart of Old Montreal at the Notre Dame Basilica. 

The route goes around the Lake Zurich (Zürichsee) & Obersee, 93km. The route is on roads and yellow trail.  It's a loop, so you can start/finish anywhere, and go either direction. 

Variations:

Road: Zurich & Obersee, 93km, gpx "Lake-Zurich-Circum"

Road: Zurich only: ~67km around Lake Zurich only, which is entirely on roads. gpx "road zurich only"

The outer loop of the Back 40 Trails system in Bella Vista, Arkansas. 21 miles, 99% singletrack. The loop starts and ends at mile marker 0 for the Back 40 loop (pictured below) at the Blowing Springs park entrance. 

The Zurich to Zug route connects two major cities in Switzerland and traverses the Albis Mountain Chain, climbing important local peaks such as the Uetliberg and Albishorn. The route covers a total distance of 34km with just over 1,000m of height gain.
