Total distance is 33 miles, 3½ furlongs and 65 locks (not counting Hatton Top Lock No 46). There are at least 4 moveable bridges of which 1 is usually left open; 4 small aqueducts or underbridges and 5 tunnels (Shrewley Tunnel (433 yards long), Brandwood Tunnel (352 yards long), Wast Hill Tunnel (2726 yards long), Shortwood Tunnel (614 yards long) and Tardebigge Tunnel (580 yards long)).
This is made up of 28 miles, 4¼ furlongs of narrow canals; 4 miles, 7¼ furlongs of broad canals; 65 narrow locks.
This will take 22 hours, 38 minutes which is 3 days, 1 hour and 38 minutes at 7 hours per day. For initial calculation purposes (before adjusting for such things as overnight stops) this is taken as 3 days of 7 hours and 32 minutes each.
But if you are single handing then you'll be slower at the locks and Tardebigge will take longer than expected, although if there are plenty of other boats around then that should make things easier for you.
