Approximated from your goal race pace
Simple percentage approximations derived from goal race pace. For precise zone prescriptions, see Jack Daniels’ Running Formula (4th ed.) and the VDOT tables.
Race splits are linear interpolations from goal pace. Training paces are percentage approximations of goal race pace: Easy ≈ 1.35× race, Marathon ≈ 1.12×, Threshold ≈ 1.07×, Interval ≈ 0.97×, Repetition ≈ 0.91×. These are simplifications of Jack Daniels’ VDOT system in Daniels’ Running Formula (4th ed., Human Kinetics). For precise zone prescriptions across multiple race distances, consult Daniels directly. The 80/20 weekly distribution principle is from Stephen Seiler’s polarized training research.

Frequently Asked Questions
How do I calculate my goal race pace for the 2-mile or 1.5-mile run?
Pace is simply time divided by distance. Divide your goal finish time by the distance to get your per-mile pace — a 16:00 two-mile is an 8:00 mile, a 13:30 mile-and-a-half is a 9:00 mile. Break that per-mile pace down further for the track: divide by four for your per-400m (one lap) target and by two for your per-800m. Enter your goal time above and the calculator does all of this, plus per-kilometer, automatically.
What pace do I need to run to pass?
That depends entirely on your branch, age, and sex — every service sets its own run standard, and they change over time. This tool does not decide pass or fail; it takes whatever goal time you enter and turns it into the splits and training paces to hit it. Get your required time from your branch’s current standard (or run your numbers through our PT Calculator), then plug that time in here to see the pace it demands.
What are splits and how do I use them?
A split is the cumulative time you should hit at each checkpoint of the run — this calculator lays them out at every quarter mile. On test day, splits keep you honest: check your watch at each mark and compare against the plan. If you’re ahead early you went out too hot; if you’re behind, you have real numbers to adjust to instead of guessing. Even or slightly negative splits — running the second half as fast or faster than the first — beat blowing up from an aggressive start.
Why are my training paces slower than my test pace?
Because most of your running should be. The Easy / Zone 2 pace this tool suggests is roughly 1.35× your goal race pace — deliberately conversational — and about 80% of your weekly volume belongs there to build the aerobic base. Only the interval and repetition paces run faster than race pace, and only in small doses. Training at test pace every day burns you out and gets people hurt; the slow miles are what make the fast ones possible.
Where do the training paces come from?
They are percentage approximations of your goal race pace — Easy ≈ 1.35×, Marathon ≈ 1.12×, Threshold ≈ 1.07×, Interval ≈ 0.97×, Repetition ≈ 0.91×. These are simplifications of Jack Daniels’ VDOT system from Daniels’ Running Formula (4th ed.), with the 80/20 easy-to-hard weekly split drawn from Stephen Seiler’s polarized-training research. For precise multi-distance zone prescriptions, consult Daniels directly.
