In applying zone focus(focusing at particular distance in advance, before the subject comes in) to shoot a bike that will come into frame, how do I correctly focus at a particular distance with a lens that has no manual focusing meter?

What are some ways to focus sharply at a particular distance with a lens that lacks manual focusing meter?

Note: Consider if the distance of the zone is not exactly known(in order to use the table).
