About This Calculator

The rowing pace calculator converts a target time over a distance into the /500m split you need to hold, and vice versa. Split is the pace unit on every Concept2 monitor: the time it would take to row 500 metres at your current speed. Because a 2K is four 500m splits, a 7:00 2K needs an average split of 1:45.0; a 20:00 5K needs 2:00.0; and a sub-40:00 10K needs faster than 2:00.0. Knowing the split for a target time is the basis of every race plan and interval prescription.

How This Works

Enter the distance in metres and your target time. The calculator divides time by distance to get seconds per metre, multiplies by 500 for the /500m split, and converts that split to watts with the Concept2 formula so you can see the power the target demands.

Formula

Split = (time_seconds / distance_metres) × 500; Watts = 2.80 / (time_seconds / distance_metres)³

Examples

You want to finish a 2K in 7:00

You need to hold a 1:45.0/500m split, which requires approximately 302 watts sustained over four 500m segments.

You plan a 5K at a 2:00.0/500m pace

Your finish time is 20:00 at approximately 203 watts — a solid aerobic effort for most club rowers.

Targeting a sub-40 minute 10K

You need a 2:00.0/500m split or faster. At exactly that pace you cover 10,000m in 40:00.

Worked examples are generated from the same formulas as the calculator above.

In the Watta App

Watta records the average split, time and distance of every piece from a photo of the monitor, and keeps a personal best per distance and per machine, so you can compare a target from this page with what you actually rowed.

Frequently Asked Questions

What split do I need for a 7:00 2K?
A 7:00 2K is an average of 1:45.0/500m — approximately 302 watts held for the whole piece.
What split is a 20-minute 5K?
20:00 for 5,000m is a 2:00.0/500m average, about 203 watts.
How do I convert split to total time?
Multiply the split (in seconds) by the distance and divide by 500. A 1:50.0 split (110 seconds) over 2,000m is 110 × 2000 / 500 = 440 seconds, or 7:20. The calculator does this for any distance.
Should I row an even split for a test?
For most rowers an even or slightly negative split (second half faster than the first) produces the best time. Going out much faster than your target average usually costs more in the second half than it gains in the first.
