What it takes
A sub 55 minute 10K means holding 5:29 per km (8:50 per mile) from start to finish. In Jack Daniels' VDOT model, that is a fitness score of about 35.8.
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 58:28 today.
Easy, threshold and interval paces come from that starting point, not from the goal, so you train at the fitness you have.
Sub 55: the endurance side
Sub 55 is 5:29 per km for just under an hour. At this level, 10K is as much about endurance as speed. Your long runs in this plan reach 11 km, about 81 minutes at 7:23 per km, longer than the race itself.
If you have only raced 5K before, the last 3 km are what is new. The long run and the threshold sessions at 5:54 per km are the two parts of this plan that prepare you for them.
Late in the plan come 1000 m reps at 10K pace, 5:29 per km. If the last rep is as quick as the first, the goal is in reach.
Your training paces
Set from a 58:28 10K, the fitness this plan starts from.
| Pace | What it is for | Per km |
|---|---|---|
| Easy and long | Most of your running. | 7:04-7:23 |
| Threshold | Tempo runs. Comfortably hard. | 5:54 |
| Intervals | Hard repeats with recovery. | 5:26 |
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.
