One thing to think about while planning, it's the 100th anniversary of the Stampede here in Calgary this year (July 6-15) so if you think you are going to be in town for any of the the first three weeks in July and you will need a hotel you better book it now. If you still can. It is supposed to be crazy busy this year and I have heard that some hotels in town are booked solid already. Also, if you are headed out to Banff in this same period you should also think about booking as it's always busy out there anyway and if Calgary is busy lots of those people will head to Banff as well.
I strongly suggest you try the ride outlined by str8, making a stop at the Longview Jerky shop before you head out towards Hiway 40.

I have been buying from them for over 25 years and it is the best Jerky I have ever tasted. It also gives me an excuse to go for a ride out of calgary west on one, south on 40 and that turns in to 541 which takes you in to longview. The shop is on the sou
Another good ride is this:https://maps.google.ca/maps?saddr=calgary+ab&daddr=50.35526,-113.78198+to:50.20838,-114.13539+to:Longview,++AB+to:Banff,+AB+to:49.89175,-115.73074+to:49.24365,-117.56726+to:49.01736,-118.35006+to:Invermere,+BC+to:Creston,+BC+to:Hope,++BC&hl=en&sll=48.980217,-120.009155&sspn=1.661989,3.532104&geocode=FYjiCgMd-p8z-SnVP4SfA3BxUzE6tlK2sTttJg%3BFTxcAAMdJNM3-Sk5xYlkVdxxUzFvfVtJDy4IZA%3BFXwe_gIdom4y-Sn3yGjyztRxUzHOZxJXDwUXpA%3BFUjqDAMdGIMc-Sn9SgyRRcpwUzFjlKzavq6vyg%3BFUjqDAMdGIMc-Sn9SgyRRcpwUzFjlKzavq6vyg%3BFaZJ-QIdzBYa-Sl7QwDl8856UzEcN9i5RwCZMg%3BFQJm7wId5BD--Cm_gGAxmS5jUzHzmtB6FVgRdw%3BFRDy6wIdFB_y-CmTiOcQqrFiUzG1VOXp-YHWZQ%3BFfeN8QIdPPPC-Cl1E-hEzPWDVDFFNZ1Ck9NkMA%3BFaEs7QIdvS0O-SmNoBKm4WJjUzHGhxdWb6sHdQ%3BFWeO8QIdf_TC-CnXx4MZyvWDVDHDK8naBnF5Bw&oq=creston&mra=ls&via=1,2,5,6,7&t=m&z=6
It is about a 12-14 hour ride from Calgary to Vancouver via 93 and 3. There are sometimes lots of RCMP, so it is a good idea to have a detector if you like to ride in a spirited fashion.
