Not alot of help features on the site, so thought I'd ask here - Love this site for unloading my rides and analyzing them, but just tried to map my own route ahead of time and am running into a problem. When I get to the approximate middle of my route (making a circle to return to my starting point) the thing seems to get a mind of it's own and wants to change my route to a more efficient one (not always what we cyclists want) or it just jumps to a whole different route. Is there a way to "lock in" your route up to a point so it won't try to cut corners you don't want to?
