MCR & ERG File Support


(Philip Amos) #1

I’m trying to understand why you have gone down the road of introducing your own file format (ZWO) for the Interval workouts rather than using the more common MCR\ERG files which people may be familiar with and which you can download hundreds of free workouts from on line libraries.

It makes no sense to re-invent the wheel…

As someone who has edited many .erg files, they are a frustrating file format.  The most frustrating thing of all may be that all time stamps need to be declared with start and stop times, not duration.  This means when you want to insert something in the middle of the file you need to adjust the times of all subsequent parts.  The Zwift format, based on my initial hand editing, is easy to work with.

Maybe what we need here is a script that makes it easy to convert .erg to .zwo files.

There is a link to a script that will convert mrc to zwo there.
