I am not sure what kind of challenge website you are looking for. If there should be stats and comparison to other people I don't know, but if you want to do it for yourself and fun, I can recommend Advent of Code (https://adventofcode.com/) , it works outside of the advent time as well, if you don't take part in the competition, but just want to solve the problems.
I found rustlings to be extremely useful when learning the language and going through The Book (TRPL). I finished both a couple of weeks ago and it was the perfect time to start doing Advent of Code in Rust, and now I feel pretty comfortable with the language. Personally, I found this to be a great way of learning Rust.

https://exercism.org/ is a mix of tutorials and challenges. It’s pretty good. You can use your own IDE and submit answers via the cli, or use their in-browser IDE. You can also see other people’s submissions, which is great, because then you can see different ways of solving the same problem.
This blog post is a good introduction on how to use Rust for programming contests. You may also find this library of common data structures/algorithms as a good reference point.
