Training for 5km vs Training for 2km

The 2k and the 5k look like neighbours on the erg ranking tables, but they ask different things of your body. The 2k is a short, brutal effort with a large anaerobic component. The 5k is a longer test of sustained power, with a heavier aerobic share.

Energy demands

A 2,000 m erg race typically takes somewhere between about six and nine minutes for most club rowers, and a 5,000 m takes roughly 17 to 25 minutes. Both are mostly aerobic, but the shorter the effort, the more you rely on anaerobic energy and the harder the final minutes feel. A 2k needs a high aerobic ceiling plus the ability to tolerate high lactate. A 5k needs a high sustainable power, which is closer to your threshold.

In short:

	2k	5k
Typical duration	About 6 to 9 minutes	About 17 to 25 minutes
Effort feel	Very hard from the first 500 m	Hard but even, with a late push
Stroke rate in the race	Often higher	Often a little lower
Training emphasis	Aerobic base plus high-intensity intervals	Aerobic base plus threshold work

Training for the 2k

The base is still mostly steady rowing, but a good 2k programme adds more hard work.

Sample sessions

• Short intervals: 8 x 500 m at about 2k race pace or slightly faster, 2 minutes rest.
• Race-pace pieces: 4 x 750 m at target 2k pace, 3 minutes rest.
• Pyramid: 500 m, 400 m, 300 m, 200 m, 100 m with rest of about 1 minute, 45, 30, 15 seconds, building pace on the shorter pieces.
• Power strokes: 10 firm strokes inside a steady piece.

Keep one or two of these a week and fill the rest with steady rowing. For a fuller plan, see how to improve your 2k erg time and the 2k erg programme.

Training for the 5k

A 5k asks you to hold a hard pace for 20 minutes or so, so the key work is longer and slightly lower in intensity.

Sample sessions

• Long intervals: 4 x 1,500 m at about 5k pace, 3 minutes rest.
• Descending ladder: 1,500 m, 1,200 m, 900 m, 600 m, 300 m with rest decreasing from about 2:30 to 1:30.
• Threshold piece: 3 x 10 minutes at a controlled hard effort, 2 to 3 minutes rest.
• Long steady rows: 45 to 60 minutes at a conversational pace.

Pacing

A common mistake in both races is starting too fast.

2k: many rowers go out a few seconds faster than average pace for the first 500 m, settle through the middle two sections and then push in the last 500 m. For example, a 7:30 goal is 1:52.5 per 500 m on average. A plan could be 1:50, 1:53, 1:53, 1:51. See 2k erg pacing strategy.

5k: aim for even splits. If your goal is 20:00, that is 2:00 per 500 m throughout. A fast start costs you more over 5,000 m than over 2,000 m because you have more time to pay for it. Hold back for the first kilometre and save a bit for the last.

Doing both

You do not need two completely separate programmes. A shared base of steady rowing supports both distances. Then a training block can lean one way: more long threshold pieces and long steady rows before a 5k, and more shorter intense intervals before a 2k. Many rowers do a 5k test early in a block to check their base and a 2k test later to check their top end. See how to do a 2k erg test.

Common questions

How often should I train? Three to five sessions a week is typical for a recreational rower, with at least one rest day. Keep hard sessions to two or three.

How long should I warm up? Ten to 15 minutes of easy rowing with a few firm strokes. Longer warm-ups help before a test.

What about technique? It matters at every distance. Poor technique costs the most when you are tired. See the technique hub.
