Estimates only consider the 76 badged cycling routes that are not event-only.
Estimates do take into account route lead-ins (once).
It shouldn't matter (much) if you ride the routes in the forward or reverse direction.
Assumes routes are all loops. Will not be accurate for a couple non-loop routes.
Estimates are based on the overall slope of each route.
It doesn't know where the hills are located within each route.
So if an estimate tells you to ride a fractional portion of a lap,
be aware that depending on that route's specific incline profile
you might need to ride a little bit further than indicated
in order to match your exact distance and climbing goal.
Take the accuracy estimates seriously. On a long ride, a 6% difference in
accuracy might mean a lot more distance or climbing than you wanted!
Oh yeah. We use a cookie to save your imperial vs. metric units
preference... Deal with it!
