I have just been on a cycle tour in Spain with some friends. They had sent me the routes on GPX files before we left. I uploaded the GPX files onto cycle travel because I like to convert them to TCX files for my Garmin. We noticed many variations on my routes and wondered why? I have done a run today and uploaded the GPX route from Garmin Connect into cycle travel and notice that there are a number of variations of the route. I will send you the GPX file and perhaps you can look at this for me and explain?
