Hi Russ,
There isn't any way to edit an elevation profile but we have a sophisticated route profile tool that you can use to apply different types of smoothing and to zoom in to sections of the route. You can see how to access the Route Profile tool in our guide on how to indentify the biggest hills on a route. You can share links directly to this tool if you like, e.g. https://www.plotaroute.com/routeprofile/1

How do I edit the elevation profile. We live in North Texas which is relatively flat. I just created a run route but the elevation profile looks like we are in the Himalayas. Yikes.
