1. What is the Concept 2 Erg Calculator?

The Concept 2 Erg Calculator estimates rowing pace (time per 500 meters) based on power output (watts). It's commonly used by rowers to predict performance and set training targets.

2. How Does the Calculator Work?

The calculator uses the Concept 2 formula:

Where:

• \( Pace \) — Time in seconds per 500 meters
• \( Watts \) — Power output in watts
• 2.8 — Constant factor based on Concept 2's calculations
• 1/3 — The cube root relationship between power and pace

Explanation: The formula shows that pace improves with the cube root of power, meaning large power increases are needed for small pace improvements.

3. Importance of Pace Calculation

Details: Knowing your predicted pace helps in setting realistic training goals, comparing performances, and planning race strategies.

4. Using the Calculator

Tips: Enter your average power output in watts. The calculator will estimate your 500m split time.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It's very accurate for Concept 2 rowing machines, which use this exact formula in their performance monitors.

Q2: What are typical wattage values?
A: Recreational rowers might maintain 100-200 watts, while elite rowers can exceed 400 watts for short bursts.

Q3: Why cube root relationship?
A: Water resistance increases with the cube of velocity, hence the inverse relationship for pace vs power.

Q4: Can I use this for other rowing machines?
A: The formula is specific to Concept 2's drag factor modeling. Other machines may use different formulas.

Q5: How does weight affect the calculation?
A: The formula assumes standard conditions. Heavier rowers may find they need slightly more power for the same pace.
