Average Split

By the Watta Team · Updated

Average Split: Average split is the mean pace per 500 metres for an entire rowing workout; it is the most important number for comparing rowing performances.

What is Average Split?

Average split is the mean pace per 500 metres over an entire rowing workout or test. It is the most important summary metric in rowing because it determines your final time and lets you compare performances across sessions. On a Concept2 PM5, average split is shown on the main screen during the piece and in the workout summary. It is calculated as Average Split = (Total Time ÷ Total Distance) × 500. For example, a 2000m row completed in 7:00 has an average split of (420 / 2000) × 500 = 1:45.0/500m. Because watts scale with the cube of speed, small split improvements require large power increases: dropping from 2:00/500m to 1:59/500m at the same pace is roughly 5 more watts. For a 2K test, holding a 1:45.0 average split means finishing in exactly 7:00.0. Average split is therefore the number to watch during pacing: start slightly above target, settle to target by 500m, then hold or negative split through the finish.

How Watta Uses Average Split

Watta extracts average split from erg screen photos and uses it as the primary metric for the Work Output component of the Effort Score. Tracking average split at the same heart rate over time is one of the clearest indicators of improving fitness.

Frequently Asked Questions

What is average split in rowing?
Average split is the mean pace per 500 metres for an entire rowing workout or test. It is calculated from total time and total distance and is the standard metric for comparing rowing performances.
What is a good average split for a 2K?
Targets vary widely by age, sex, and experience. Competitive male club rowers often average 1:40-1:50/500m; competitive female club rowers 1:55-2:08/500m. Recreational rowers commonly average 2:00-2:30/500m.
How is average split different from current split?
Current (instantaneous) split updates in real-time and fluctuates with each stroke. Average split is the running mean for the entire piece. Average split is the metric used for rankings and performance comparison.
How much does 1 second per 500m matter?
A lot. Due to the cubic relationship between split and watts, a 1-second improvement at 2:00/500m represents approximately 5 additional watts. Over a 2K, 1 second per 500m equals 4 seconds on your total time.
How do I pace a 2K using average split?
Start the first 10-15 strokes slightly above target split, settle to your target average by 500m, hold it through 1500m, then sprint. Your final average split should equal your target if you paced well.
