Is this goal realistic for you?

According to Daniels’ model, a runner capable of this goal runs roughly these times at the other distances. If your best recent time at one of them is close, the goal is within reach in one build. If it is far off, aim for an intermediate step first.

A typical week, in the middle of the build

An illustration, not a prescription: the right week depends on the one before, on how tired you are and on your schedule.

1. MondayRestFull rest. This is when the training takes hold.
2. TuesdayIntervals (VO₂max)15 min warm-up, then 6 × 1 000 m at 4:40/km, 2–3 min jog between. 10 min cool-down.
3. WednesdayRestRest, or 30–45 min of very easy cycling or swimming.
4. ThursdayThreshold15 min warm-up, then 3 × 10 min (2 min recovery) at 5:05/km: comfortably hard. 10 min cool-down.
5. FridayRestFull rest. This is when the training takes hold.
6. SaturdayEasy run35–45 min easy, at 6:11–6:49/km, conversational. Finish with 6 × 20 s strides, fast but relaxed.
7. SundayLong run70–80 min easy, at 6:11–6:49/km.

The four stages of the build

1. 01 · 3 weeks

   Base

   Mostly easy running, strides and one short threshold session. Volume first, speed later.

2. 02 · 3 weeks

   Build

   Two quality sessions a week: intervals and threshold. Volume rises in steps, with a lighter week every third or fourth week.

3. 03 · 3 weeks

   Specific

   Race-pace blocks get longer. This is where you learn to hold race-day pace.

4. 04 · 1 week

   Taper

   Volume drops by 30–50 %, intensity stays, in shorter doses. Arrive fresh, not rusty.

What makes the difference

• About 80 % of your running time easy. Easy runs done too fast tire you out without making you faster.
• Grow volume in small steps, and plan a lighter week every third or fourth week.
• On race day, start at 5:00/km and no faster: early kilometres run too fast are paid for at the end.
• Sleep and rest days are part of the plan. Pain that changes your stride is a reason to stop, not to push through.
