I know that "The Real Barenziah" mentions that it takes two-three weeks or something for a trading caravan - which would move slowly - to get from central Skyrim (Whiterun?) to Riften.
Generally, you can say that 30 km/day would be a good but not excessively high travelling speed by foot (I've previously looked at several sources to come up with this, I'm not saying it's the absolute number, but something like it). A caravan would move slower, say 20 km/day, which would make the distance between Whiterun and Riften around maybe 300-400 km. Or something like that.
If someone likes, check "Barenziah" for the actual distance and number of weeks (I don't remember if it really was Whiterun to Riften).
