While exercise bikes usually provide an effective 'distance ridden' reading that can be entered in as a manual ride, many spin bikes produce no such measurement.
For those on a spin bike that doesn't provide a reading, you can use the following conversion chart as a guide for recording spin classes:
|15 minutes||4.65 miles|
|30 minutes||9.3 miles|
|45 minutes||13.95 miles|
|60 minutes||18.6 miles|
