Split Time

By the Watta Team · Updated

Split Time: Split time is the pace expressed as the time it takes to row 500 metres on an ergometer, displayed in minutes and seconds (e.g. 2:00.0/500m).

What is Split Time?

Split time is the most fundamental metric in indoor rowing. It represents your current or average pace as the time required to cover 500 metres. A lower split time means you are rowing faster. For example, a 2:00.0 split means you would cover 500m in exactly 2 minutes. Split time has a cubic relationship with power output (watts) — small improvements in split time require significantly more energy. Going from a 2:00 to a 1:55 split represents a much larger power increase than going from 2:10 to 2:05. Most Concept2 monitors display split time as the primary pace metric, making it the universal language of erg performance.

How Watta Uses Split Time

Watta extracts your split time directly from erg screen photos using AI-powered OCR. Your split feeds into the Work Output component of the Effort Score algorithm, which accounts for 35% of your total score. Watta also tracks your split across sessions to show pace trends over time.

Frequently Asked Questions

What is a good split time for rowing?
A good split time depends on the workout distance and your fitness level. For a 2K test, competitive male club rowers typically hold 1:40-1:50, while competitive females hold 1:50-2:05. For steady state training, splits are usually 15-25 seconds slower than 2K pace.
How is split time different from pace?
In rowing, split time and pace are the same thing — both express the time to cover 500 metres. This differs from running, where pace is typically per mile or kilometre.
How do you convert split time to watts?
The formula is: Watts = 2.80 / pace³, where pace is in seconds per metre. For a 2:00.0 split (0.24 s/m), the power is approximately 203 watts.
