Which gateway are you pinging?
If you are behind a router and you are pinging the Default Gateway then you are not achieving much as all you are pinging is you router.
If you are pinging the ISP's gateway to the Internet then that would be fine.
However I suspect your ISP would likely get a bit angry having someone constantly pinging them for an hour, it could be construed as a DoS attack.
