I'm pretty sure that one of the Dark Peak completers from a couple of years ago was of Asian (Chinese or Japanese) lineage. Don't know of any from India/Pakistan.
We had a thread some time ago about *foreign* completers (I use the word advisedly) and it seems that there are remarkably few to date, probably less than half a dozen Irish runners for example. It does seem to be a very local challenge but does have some visibility overseas so we might get a few more. The difficulty of course for anyone not residing in the UK is getting a good weather window to coincide with a trip here.
Good luck to the pair of you!
