That is some journey!!! You don't want to go via London. There may be some other ways to do it, but the best I can find for you is as follows:

Number 93 bus from Robin Hoods Bay to Scarborough
RHB 9.49am Scarborough train station 10.30am

Train from Scarborough to York
Scarborough 10.48am York 11.38am

Train from York to Birmingham New Street
York 12.34pm Birmingham 2.27pm

Walk from Birmingham New St to Birmingham Moor Street
About 10 to 15 minutes

Train from Birmingham Moor Street to Stratford Upon Avon
Birmingham 3.29pm Stratford 4.21pm

Number 21 bus from Stratford to Chipping Campden
Stratford 4.45pm Chipping Campden 5.20pm

This is travelling on a weekday. Travelling on a weekend would be even harder!!!

Good luck with this – you will need it!

I took most of this route to get home to Liverpool Lime St.
Number 21 bust to Stratford upon Avon, train to Birmingham Moor St, walked to Birmingham New St. (well signposted and took me 10 mins, then train to Liverpool. All connections were on time.

It is a good 15 minute walk from the railway station in Stratford to where you need to pick up the number 21 bus.

Hi Calluna,
Sorry to hear you had 'the bug' during the walk but well done for sticking at it. I'm having thoughts of a LEJOG adventure in a couple of years time so will check out your friends blog.
Glad all the new gear performed for you, check out Alpkit's website for a decent light sleeping bag (cheapest quality down bags you'll find).
Cheers
Les

Hi Bliss, thanks so much for your response. This is a great help as we now have some direction. We are really looking forward to getting back to the UK for some walking. Just love the combination of beautiful countryside, pubs, b&b's & history.

Yes - we do those things quite well! Sadly the first of these is dependent on the awful weather we have sometimes!!!
