I just got Mapmyride last night. I need to explore it more. Though on an initial test, it didn't want to map along a specific towpath I'm fond of. It went from trailhead A to trailhead B focusing on streets and avoiding the path. Perhaps I just need to toy with it more. Settings and such.

Wahoo app looks interesting. Sadly is won't connect with my Gear Fit 2 which is my current HR monitor. I do like the clear display and the info it shows and tracks. Neat stuff.
Yet it still goes against my initial goal to keep some stuff dispayed on a puter, and other stuff on my phone. I think I would prefer to have something like the Cateye displaying distance, speed, and mounted next to my phone running gps, s-health, music. etc. Though I think my Girlfriend will get good use of the Wahoo for her simpler set up.

I absolutely appreciate all the input so far. Thanks guys.
