Dear Deb D
Is Billericay near Dunmow ?? Well I wouldn't like to walk it, I suppose Billericay to Chelmsford is about 12 miles, then Chelmsford to Dunmow I suppose is about another 12 miles.
But if you go into Google and put in 'Billericay' in the Maps section, it will show you Billericay, then scan up to Chelmsford, then to Braintree, then ease to the left, and before you know, you'll be in Dunmow.
Rgards,
