Adjusting movement speed on players

So I’m making a deathrun map and obviously Death(s) should be faster than the Runners.
How should I do this? Just basic funcs and triggers wanted, no need for a wall of text.

Not sure if this will work as I haven’t tested this but you could try tying a trigger to this: https://developer.valvesoftware.com/wiki/Player_speedmod

Seems to work, thank you.
