The process to convert a Gaia Route to a Track is only a bit complicated as I couldn't find a way in Gaia to convert it back nor GPX Studio worked for me. I decided to look into the html tags within the first segment and replaced all the Route related tags with the Track tags found in segment two. Then I added the track points from the second file to the first file and imported that back into Gaia. Now I have a single GPX file with combined stats. See below.
We covered nearly 58 kms in 3 1/2 hours with not to many dramatic hill climbs or descents. Though our drive through Qudra Secret Dunes was a faster pace and fun.
