It is only 1/3 or 1/4 of the position under covered call. 3/4 or 2/3 of position can still enjoy the run up, and you can also try to either buy additional shares before the run up if you really dont want that to be called out, or roll up 1/3 of covered calls.
Worst case is you take some profit but still have majority of position enjoy the run up.
