This is the long term schedule for LHC [1] where you can get an idea about the plans for runs, maintainace and upgrades. The current plan is to run with HL-LHC (High Luminosity LHC) starting from Run 4 (2030) until Run 6 (2041). These plans will probably be extended because of different factors, but this gives the overall plan for LHC. And also why we start thinking about the next collider because it will take decades to be designed, build, commissioned and tested. This will require huge amount of efforts, community built and collaboration on a global scale.
