Set ERG set to single steady wattage?

All Workouts are variable? Can a single wattage be selected some way?

Yes you can build a Workout with one single wattage.

See this one.

Or this one:

You could build a single long block at whatever percentage of FTP you want, but I’d suggest you put at least a 5 minute ramped warm up at the start and then short recovery section after the warmup, then your “work” block.

That should do it. Thanks Gerrie
