What is the maximum size of a course name (number of digits?)

What is the maximum length (number of digits) that a course name can be to properly load if pinned in Garmin Connect.

I have found that Ride with GPS Courses with long titles will not show up in my in my Edge Explorer 2 "Last Course Added" when pinned in Garmin Connect. 

Example:  

Stonelick Lake Beach to Mount Orab‘s country Inn restaurant. will not show up in when pinned in Garmin Connect

When the course name is changed to:  Stonelick SP to Mt Orab+Country Inn it WILL show up when pinned in Garmin Connect
