Actually ridewithgps seems to have working Google Maps (i don't know, for how long though), but with those pesky winter restrictions. After LFR changed their maps i went back to ridewithgps (used it after t4b) and as of now it seems to be working, but i still use LFR for the stage and climb profiles. Quickly checked if Chile works and it seems to be working ok. As of now it seems LFR is working relatively well with recent combination of having Google elevation profiles with OSM's tracing (which has a problem of not recognizing highways). I personally rarely use Cronoescalada. It's a good site but their elevations are bad to at times horrendous (even up to 30-50m difference) and i found LFR's route features (climbs, sprints etc.) a bit easier and quicker to add. However, i don't know, if it got any better.
