there should be an option to tick on or off which add the possibility to turn off recalculation of the route when we switch the sport.
Often I dont choose the right sport and I build my route, and when i realize my mistake, its too late, i switch from road bike to running, and all the route is recalculated and use other road !! Its painful and force to start over.
It should be an easy option to implement.
An other interesting option would be to be able to build 2 routes at the same time on the same map tab.
And be able to compare both route; lenght, D+, segment, and then save both in separate files.
