Goal time · 5K
A 20:00 5K works out to 6:26 per mile, or 4:00 per kilometer. Below are the mile splits for a slightly faster second half, the halfway time to aim for, and the training paces that go with this goal.
The numbers
This plan starts about 1% slower than goal pace and finishes about 1% faster, so the second half is slightly quicker than the first. The elapsed column is what your watch should read as you pass each marker.
| Mile | Pace for That Mile | Elapsed Time |
|---|---|---|
| 1 | 6:29 | 6:29 |
| Halfway (1.6) | 6:27 | 10:04 |
| 2 | 6:26 | 12:56 |
| 3 | 6:23 | 19:19 |
| Finish (3.1) | 6:22 | 20:00 |
Measured against the latest published results of 5,229 5K races on RunSesh.
One edition per race, from RunSignup races with published results. Fields include walkers and charity entrants, so this describes these races, not every runner in the country.
These are the paces for a runner who can already race a 20:00 5K, worked out with Daniels and Gilbert's VDOT formulas, the method behind the training tables in Daniels' Running Formula. If your most recent race is slower, train at the paces on the page for that time.
Most of your weekly miles, including the long run.
Steady longer runs at the pace this fitness would hold for a marathon.
A steady run of about 20 minutes, or longer repeats with short rests.
Repeats of 3 to 5 minutes, with easy jogs between.
Research from Abbiss and Laursen, published in Sports Medicine in 2008, found that distributing pace more evenly during events lasting more than two minutes may improve performance times. Keeping the first half controlled is what makes a slightly faster second half possible, and together they add up to a race that stays close to even throughout. Use the halfway marker as your main checkpoint: if you feel measured there, you have room to push into the finish.
Daniels and Gilbert's VDOT formulas treat a 5:51 mile as the same performance as a 20:00 5K, giving you a concrete fitness benchmark from a distance you may have raced recently.
The RRCA pace chart developed by Amby Burfoot puts it clearly: "don't begin with a future goal time. To do so increases risk of injury and/or overtraining." Basing your paces on a recent result rather than a target keeps the training load grounded in where your fitness actually stands.
USATF measures certified courses along the Shortest Possible Route, with a one-part-per-thousand Short Course Prevention Factor built in. A runner who drifts from that line covers more than the stated distance, so a watch can show a faster average than the pace the course actually required. Checking the course markers, not the watch's laps, gives you the clearer picture.
Daniels and Gilbert's formulas treat a 41:28 10K as equivalent to a 20:00 5K. If you've raced a 10K recently, comparing your result against that time tells you how your current fitness relates to the 5K goal before race day.
