Erroneous time on route

I've created a route between Whitehorse, Yukon and Atlin, British Columbia. The Route Properites page indicates the correct mileage of 106 miles. The time, however, indicates 5 hours and 13 minutes. That would equate to an average speed of 20 miles per hour. For the same route, Google maps shows 109 milles and 2 hours 13 minutes enroute, or 48 mph average. The activity I've selected is 'Driving'. The customized speeds are interstate 55; major 50; other 45; collector 35; residential 25.

 

Any thoughts on why the time is more than double what it should be?

Also, on the elevation data page, it says "The current map does not contain any elevtion data on the selected route(s)". Why is that?

Thanx in advance for any feedback.
