What it takes
A sub 45 minute 10K means holding 4:29 per km (7:14 per mile) from start to finish. In Jack Daniels' VDOT model, that is a fitness score of about 45.3.
The 10K pace chart has the splits for it. It also covers every other time from 30 to 80 minutes.
One consistent block of training usually moves a runner a couple of points. So this plan suits someone who runs the 10K in about 47:13 today.
Easy, threshold and interval paces come from that starting point, not from the goal, so you train at the fitness you have.
Sub 45: one quality day, done well
Sub 45 is 4:29 per km (7:14 per mile). This sample uses four days a week and about 37 km at its peak, with one hard session each week. The rest is easy, at 5:48 to 6:04 per km.
That single session has to count. Arrive for it fresh, warm up for 10 to 15 minutes, and run the reps at 4:26 per km, not faster. On four days, one session done properly is enough.
The long run reaches 11 km, about 1 hour 5 minutes, a little over the race distance. For a 10K at this level that is enough.
Your training paces
Set from a 47:13 10K, the fitness this plan starts from.
| Pace | What it is for | Per km |
|---|---|---|
| Easy and long | Most of your running. | 5:48-6:04 |
| Threshold | Tempo runs. Comfortably hard. | 4:49 |
| Intervals | Hard repeats with recovery. | 4:26 |
The VDOT chart has the full set, repetition pace included.
The plan, week by week
4 running days a week, peaking at about 37 km. Week 4 is easier, and a taper leads into race day.
Long runs are on Sunday. Hard sessions are on Tuesday.
