When putting a trip into the Nav, it gives you the time expected to complete it.

Is the calculation based on riding at the max speed limit for each road?
 
I always beat the estimated time, usually by half an hour or so over a mixed roads 60 mile route. Google maps does a much better estimate.
 
When creating a route in BaseCamp or Mapsource, the software creates an estimated time to complete the journey. This calculation is based on several criteria, one of which (naturally enough) the maximum speed - ie the known speed limit - for the road(s) chosen. What it does not do is make any allowance for you stopping en-route to do anything at all *.

When the route is imported into and then displayed on the device, the estimated time may change. This change is due to the device using sometimes different criteria.

Use the pc and device generated time estimates as a guide only. You’ll know for yourself (or at least have a pretty good idea) how long it will take you to ride say, 100 miles down a motorway or 50 miles down goat tracks. You’ll also know whether it takes you all day to ride 250 miles or whether you knock it off before breakfast. If you are ever unsure, always relate the distance shown on the device to something you know. For example: You live in Manchester. London is 200 miles away. 200 miles on the continent is the same distance as it is here. How long do you think it will take you to ride from Manchester to London, using (A) motorways (B) a mixture of roads (C) every goat track or mountain pass you can find?

When you ride your routes, before you set of on the day’s ride, take a quick look at the device generated time estimate to complete the journey. At the end of the day, how long did it take you? Was the device right or wrong? If it was wrong, by how much was it wrong? You’ll get used to it. Not least, you’ll get used to how long it usually takes you to get from A to B, over all sorts of terrain, road types and distances.




* If you use BaseCamp, you can factor in your own stopping times at specific points along the route. The software will take these into account when making its total journey time calculation. The Garmin device will do the same.
