Run a Pocket Query on jholly's posted bookmark list and you'll have a GPX file of the route. That's how many of us do it. Slicing and dicing in GSAK is just a bonus.
FYI, sharing a public GPX file is against the site's TOU.
Thanks for the help, the pocket query finally worked, it seems like it has a mind of its own. Sometimes it is almost instantaneous, sometimes it takes several hours. The one we needed in a hurry finally showed up this morning of course.
