Fifteen miles is a marathon-block session, not usually a race
Most runners meet 24 km as a long run inside a marathon build rather than as a race, and that changes how to read the chart. The row you want here is normally not a target: it is the pace you expect to average on a long run, which for most people sits 60 to 90 seconds per kilometre slower than goal marathon pace.
That gap is larger than most runners are comfortable with, which is exactly the problem. Why your easy runs are probably too fast covers the cost of closing it, and the long run explained covers how far and how slow this session should actually be.
If you are running this distance to hold on to fitness between race blocks rather than to build it, how long marathon fitness lasts covers how much of it you keep and for how long.
15-mile pace questions
Why is the 15-mile pace chart useful?
15 miles is a common long-run distance in marathon training programmes. Knowing your 15-mile pace helps you gauge marathon readiness - your marathon pace should be close to or slightly slower than your comfortable 15-mile pace.
What pace should I run my 15-mile training run?
Long training runs should be at easy or conversational pace - typically 45–90 seconds per km slower than your goal race pace. If targeting a 5:00/km marathon, run your 15-miler at roughly 5:45–6:30/km.
How do I predict marathon time from a 15-mile run?
Your comfortable 15-mile pace is a useful indicator of marathon fitness. Add roughly 15–30 seconds per km to your 15-mile easy pace to estimate your sustainable marathon race pace.
