These formulas assume you have trained for the distance. They convert one performance into an equivalent one; they cannot know whether your longest run was 30 km or 10. A marathon predicted from a 5K is the time you could run if your endurance matched your speed, which for most people it does not — the further the extrapolation, the more the prediction becomes a statement about your training rather than your fitness. Not medical advice; if you are new to long-distance running, build up gradually and get checked out first.
