Two things you can check:
1. When you are on the server type /privs and look if you have "fast" in it. If not, you have to ask an administrator. To find the name of the administrators type /status.
3. I f you have fast, go to your minetest [main menu]. Click the "settings" tab and then click Change keys. To enable run/fast you can see which key toggles it on/off. To run fast in the game itself, you must use the direction key(s) in combination with the key that is mentioned by "Use"
Good luck!
