How do you delete rides

[gidmoose]

I went to the manage rides screen, and I'd like to delete a few that I had created with mymaps.google.com and then uploaded.

For instance, there was one I ride near Mount Whitney (the Highest mountain in the lower 48 states), which when you start riding is just blue.   There's no land in any direction.
There are two others I created - Bryce Canyon and also The Grand Tetons, which have no pictures at all on the thumbnails, and a message that they can't be explored.

Apart from that, I really do like VZfit.

I notice flaws, like walls of scenery that suddenly end, or scenery that seems totally flat and depth free, or when I climbed the "Pikes Peak Colorado" road, the scenery off the mountain was often compressed to about an inch high.   (There were a few exceptions).    There is also a tendency - perhaps when the road dips, to suddenly seem as if you are cycling into the air.

Maybe these problems will be fixed one day, but if they depend on the depth finders of Google cars, perhaps they can't be fixed.

Anyway, back to the question - is there a way to delete your own rides?

Thanks.
