More love for the WahooFitness KICKR in this release! ERG/MRC files contain data to control the resistance of the KICKR trainer, and while has had an ERG importer feature for some time, converting ERG/MRC files into iMi workouts in your Personal Workouts library, you can now send ERG and MRC files direct to the app.

The file must have a .erg or .mrc file ending, and conform to the standard or PerfPro ERG format (however distance and slope intervals are not supported).
