I was messing with the lua file and check the functions, they have easy reading names so, I was able to add a way to make it so you aren't able to run if you have any type of exertion moodle, even out of breath! so if anyone is intersted here is the code, just go into:
steamapps\workshop\content\108600\3397207461\mods\RunAndReload\42\media\lua\client\RunAndReload_Lua and open the variables.lua file and paste this:
