Difference between ERG and simulation
Trainer and modes
ERG and simulation are different ways of controlling the trainer. ERG tries to maintain a target power; simulation changes resistance according to gradient, speed, or other parameters.
Recommended steps
- Use ERG for structured power-based workouts.
- Use simulation when you want a feeling closer to a route or race.
- In ERG, you maintain cadence and the trainer adjusts resistance.
- In simulation, you manage the effort as if there were terrain.
- If you are doing power intervals, ERG is usually more comfortable.
