For anyone making a weekend of the Spring Rally there are some specially selected runs and guides on the Spring Rally web site at http://www.springrally.co.uk/explore.html put together by the Yorkshire Ridings region
If these don’t tickle your fancy try the archive section of the YR website where there are many more including a couple of treasure hunts for them that like a challenge (contact me if you need the answers)
