For those using and/or familiar with the operation of the Cycle Meter App (Iphone 6 PLus), is there anyway to merge multiple routes into one route? Thanks.

No, because all routes are GPS coordinates by time. If you want to take the time, you could take the largest part of an existing route you want to use and upload it to a web site that you can create routes with. Then edit that route and add the other routes manually. When done, export from the web site and import the route into Cyclemeter. To try and modify a GPX/TCX file manually will be a bigger task than what you will want to take on.

Perfect very helpful. I did not see a possibility of doing so within the app but wanted to make sure I was not overlooking anything as I am new to this app. The method you described to accomplish it is definitely more than I want to tackle or worth doing. So thank you.

Yes it is a bit of extra work. I have done it once and it was a bit of a pain. FYI, if you are going to download a route that someone else created and has sent you or download a route from a web site, don't save the file as a Route. Instead, save it as a Path. The difference is that, when saved as a Path, Cyclemeter will strip all the ride data from the file and just leave the GPS coordinates that creates the route. This is what will show up when you want to do this ride. When you are ready to do this ride, select the Path as your route and start the ride. When you save the ride at the end, Cyclemeter will save it as a New Route and place it in the Routes section. The original Path will still be in the Path section until you delete it.
