Timewise, assuming that Deerfoot has slowed down at least a little bit (which is common). But the difference in kms isn't neaerly as much as it might seem, probably only 1 or 2 kms. Deerfoot goes east and west to much and often.

EDIT: just comparing the distances on google maps right now.

I set the start point on HWY 22X just west of deerfoot, and the end point at the corner of Airport Trail and Barlow trail. Google maps says that the distance up Deerfoot is 35.7 km. If I place intermediate points in so that it takes me along 84th Street to 17th to Stoney to CHB, and then down Barlow, it says 41.9 km. But then, we have to delete the distance between where stony is and where 88th/84th Street is (800 metres ish x 2), AND the distance between Airport Trail and CHB (1.6km x 2). Altogether I have to subtract 4.8 km from the 41.9 that Google Maps gives me, so that leaves 37.1 km. However, the East ring road will have a smoother curve to turn northbound and to turn west onto Airport Trail than the corners at 88th Street and at CHB are - that would save a couple of hundred metres, let's say 200.

So, then distance up Deerfoot is only ~1.2 km shorter than the distance up Stoney - roughly 3 percent shorter. 3 persent is easily made up if you can average a higher speed on Stoney. Certainly you won't be able to average a higher speed on Stoney all of the time, but for good chunks of the daylight hours you certainly would. Like I said, if there is ANY kind of slowdown on Deerfoot, it's going to be faster to take Stoney. If all of a sudden Stoney gets posted with a 110km/h speed limit, it would be faster at almost any time of day.
