Yep, this is approximately this loop. http://www.mapmyride.com/ca/calgary-alberta/bow-fish-creek-glenmore-reservoir-loop-6-route-20396174
Getting onto and off of the loop usually brings me up to around 65k, I also don't go through downtown, I just follow the bike path up the Elbow river until Inglewood ish.
This is a pretty good loop. There's lots of other good hills to climb in that area as well.

Also Glen Eagles Drive in Cochrane, Highwood pass in Kananaskis, the road to Norquay are pretty good ones!
