"I met the girl who encountered this mysterious record holder today. I asked her if she could remember anything else about him ...... evidently he is an undertaker! This either identifies him or deepens the intrigue!"
I had the great pleasure of meeting this guy myself (last Sunday).
He does indeed ride a motorcyle (he arrived at the TIC on one)
He is an undertaker! (told about where he works).
He won the Lyke Wake race 7 years running (sic).
He has just set a new record for the Cleveland Way.
He lives in Driffield.
I did ask his name but forgot to ask if I could use it on the forum .... as I was working it would be unwise of me to use it without his permission
You may now recognise who it is, otherwise, Googling will help.
