I'd guess that, depending on the condition of the running board rubber, attempts at "rejuvenation" may not be very successful. Back when I barely had two nickels to rub together we used to coat them with several coats of DuPont's blackwall tire paint, that stuff that the used car dealers used to try to make a sow's ear look like a silk purse. I suppose the stuff is still available, and it might well temporaily improve the appearance. But it has no restorative powers, just a top coat.

If some chunks are missing, you might try filling the spaces with black RTV silicone rubber, though the blackwall tire dressing isn't going to want to adhere to those places. Truck bedliner goop is perhaps a better choice for little patches here and there.
