Canceled or Cancelled?  Some use the first, and others use the second.  (The calendar events have the second.)  Here's something to read while not riding:  https://www.grammarly.com/blog/canceled-vs-cancelled/.  Same rules apply to modeled, fueled, labeled, rivaled, traveled, shoveled, tunneled, etc.  Try them with two 'els' and see how they look.  Of course, use whichever one you like.

Tomorrow's ride is canceled.  We will try the Pi ride again next Tuesday.
