^This. Get a free Strava account. Upload your ride. Go to that workout (as opposed to your home page) and look for the "Edit" button which looks like a pencil icon. Don't go there! To the right of that edit button is a button with three circles (ooo) which means "more choices" I think. Click that one! Then click "Crop" in the menu that appears. You can then use a slider to subtract from the beginning or the end of your workout. Save it. Export the .GPX file to your computer/laptop. Once you have that GPX file you can upload it anywhere you choose. I like Endomondo. It def works there. Or.....just use Strava for everything. I gave up Strava because Endo is more social and Strava refused to add a longboard/skateboard category.

Cheers!
