Although it won't be revealed by until a press conference (in both Leeds and Paris) on 17th January, "usually reliable sources" suggest the following is likely: -
Day 1 - Saturday 5th July 2014 - the start will be in Central Leeds, heading out through the grounds of Harewood House and then up and across - probably Sutton Bank - through The North Yorkshire Moors National Park - and across for a sprint finish on the sea front in Scarborough.
Day 2 - Sunday 6th - is expected to start in York City Centre heading across into The Yorkshire Dales National Park, coming down - hopefully through Ilkley and up past The Cow and Calf Rocks on Ilkley Moor, then down through Halifax and maybe ending in Sheffield City Centre.
All this is yet to be confirmed! It may prove wrong. I'll bet it's not far off the mark though!
