Do different horses have different speeds?

All the horses I see available at the different stables cost 1000 gold. Do they all have similar qualities, or are some faster than others as it was in Oblivion?

All horses in Skyrim have the same speed and hardiness,they are all draft types that resemble a Clydesdale, and all cost 1000 septims.

There is one horse in Skyrim that, while unable to run faster than regular horses, can sprint further.

After reaching a certain point in the Dark Brotherhood quest line, you're given access to Shadowmere. Shadowmere seems to be able to sprint for longer distances than regular horses, and is also much harder, if not impossible, to kill.
