What pace is a 47 minute 10K?

4:42 per kilometre, held for the full ten kilometres. On a 400 metre track that is 1:53 for each of the twenty-five laps, with nothing left over. In imperial units it is 7:34 per mile, or 7.93 mph. Halfway at an even pace is 23:30.

What should I go through 5 km in?

23:30 for an even race. The two halves must add to 47:00, so anything you take off the first half has to be given back in the second — go through in 23:00 and the second half has to be 24:00, a minute slower than the first. Most 10K personal bests are run with the halves within about fifteen seconds of each other.

What should the clock read at each kilometre?

At an even 4:42: 9:24 at two kilometres, 18:48 at four, 23:30 at halfway, 37:36 at eight and 47:00 at the finish. On a track the same splits fall at laps five, ten, twelve and a half, twenty and twenty-five — a 10K is exactly twenty-five laps, so it starts and finishes on the same line.

How much quicker is 46 minutes than 47?

Six seconds per kilometre. Ten kilometres divides a minute into six-second steps, which is half the twelve seconds a minute is worth on a 5K — so a whole minute is a smaller pace change here than at the shorter distance. 47:00 needs 4:42 and 46:00 needs 4:36; going the other way, 48:00 needs 4:48.

What does a 47 minute 10K suggest at other distances?

Using Riegel's model, roughly 22:33 for 5K, 1:43:42 for a half marathon and 3:36:13 for a marathon. Note the 5K figure — it implies a 5K pace about 0:11 per kilometre quicker than your 10K pace, which is the usual gap between the two.

Does a hilly course change the plan?

Yes, and the change is to stop watching pace. On a rolling course an even pace requires an uneven effort, which is exactly backwards — ease off the climbs, let gravity help on the descents, and accept that individual kilometre splits will vary widely. Chasing a target pace up a hill is one of the most reliable ways to ruin the second half of a 10K.

How much does weather affect a 10K?

More than at shorter distances, because you are exposed to it for longer. Heat and humidity are the dominant factors — above roughly 15 °C most runners begin to slow, and a warm humid morning can add well over a minute to a 10K at the same effort. Wind costs more into a headwind than it returns with a tailwind, particularly on an out-and-back course.

How often should I race a 10K?

Every four to six weeks suits most runners. A hard 10K is a substantial stimulus and leaves real fatigue for several days, so stacking them crowds out the comfortable running that actually builds the fitness. The weeks between are better spent on easy volume plus one structured session than on another race.

What should my weekly training look like?

Mostly easy, with a small amount of faster work. The usual shape is three to five runs a week with the large majority run comfortably enough to hold a conversation, one session of intervals or a tempo effort, and one longer run. Ten kilometres is far enough that aerobic base matters more than speed, which is why the easy running is doing the heavy lifting.

10K in 47 Minutes — Pace, Splits and Halfway Plan

A 10K in 47 minutes means holding 4:42 per kilometre — 1:53 for each of the twenty-five laps of a 400 metre track, with halfway at 23:30. That is 7:34 per mile, or 12.77 km/h. Forty-seven minutes is where consistency starts to show plainly. Three unhurried runs a week for two months moves this time ...
