Camino Ingles Start

Oh, dear God! Are you serious? Where does it start? If you have some delicious Wensleydale cheese, have some now. With a few crackers. Then think: the Camino Ingles. How did it get its name? I don't actually know, but I have gleaned this much: it concerns the name of the pilgrim route of those who landed from foreign shores speaking English, or anything that was neither Spanish, nor French, nor... other Continental languages.
So, back to your fair question. In modern times, there are two recognised starting places in Galicia. La Corunna and Ferrol. I have also gleaned that the first is the original, traditional. Who knows? I have been converted to cynicism as a result of my membership of this forum.
If you want to get a Compostela, find a 25km route in UK and prove that you walked it, then begin in La Corunna. Or else, get yourself to Ferrol. It exceeds the current requirement of 100km as minimum for a compostela.
Most of all, enjoy it. It is short, but contains the elements of pilgrimage. Which is what it is all about, isn't it!

Most people think of the Camino Ingles as being the route from.either Ferrol or A Coruña to Santiago. There have been attempts to create routes within England which link sites with historic connections to pilgrimage. I think you may mean one of those rather than the Galician route. Those who have walked at least 25km of one of several English routes and have a stamped credencial can receive a Compostela after walking the route from A Coruña which is normally too short to qualify. There is some information about the recognised English routes on this page: https://www.caminoingles.gal/en/o-camino-ingles-en-gran-bretana

The Camino Inglés in the north east of England starts at Finchale Abbey, which is about 4 miles north of Durham, and runs to Escomb, west of Bishop Auckland. However, there are plans to extend it into Yorkshire, with the idea of eventually reaching York?
