Is it possible to somehow archive or retire previous rides from my stats? I did quite a bit of local riding on a road bike a number of years ago, and am now doing some of the same routes and segments on a hybrid bike at a more leisurely pace. Needless to say a lot of my PRs are from years ago. Can I somehow hide those without deleting all the rides?

It is mainly to stop the PRs on my Hammerhead Karoo being now meaningless ones from years ago, that I am never going to catch!
