Ammendment to the end date

I am planning on staying with some friends on the last night of the trip, at the weekend we met them and decided that this would be an excellent time to stay with them for the weekend. This means that the end of my ride will be postponed.  I will arrive near Middlesborough on 21 May, the following day my wife and some other friends will join us for the weekend and we will all leave on Sunday 24 May, the final riding day arriving at the Humber Bridge in the afternoon.
