So Google maps doesn't have any consistancy if you go wrong (& aren't looking at that exact point) it just recalculates and you carry on regardless and you can arrive at totally inappropriate roads (A12 I'm looking at you!)
So when coming back I looked at Cyclestreets but that didn't work like I expected it, so I went back to google maps and ended up riding back and forth on one road where the direction of travel changed every 30/40 seconds & it kept telling me to go back the way I came (both ways)
& then there was a bridle path than was under water (not googles fault but it cocked everything up!)
So I probably did about 30 miles and I am knackered!
Is there a proper satnav I can use on my phone? That works for a bike and doesn't present me with near motorway versions of A roads or 'styles' 
Oh and i fell off! No rhyme or reason just cycling along and next thing I knew I was on the floor - picking myself up and I nearly got knocked over my a car that had stopped for me falling.....I guess I took too long to pick myself up
So I need to get out there again tomorrow or I'll lose my nerve
