Minecraft wiki entry for Getting_to_the_worldborder, associated text: Walking/sprinting to the world border is a very tedious task. The average speed you can go is 5.6 blocks per second so it would take around 54 days to go to the world border assuming you go non-stop and you encounter flat terrain for the most part of your journey. However, walking does have its perks, as you can gain recognition for manually walking such a large distance. An example is Killo's journey to farlands which was 12.5 M blocks away and Fig's journey to the border.
