Hi, Rusty!
Yes, it was indeed Jo Pavey!
I like Jo! and I enjoyed her autobiography.
The contestant did not know the answer.
Yes, I think I remember Laura running in Edinburgh last year....a cross country relay race?
I didn't know "finger -fumbler" either......
The question was what was similar in words to "finger-fumbler?"
The answer was "tongue twister".
I have looked up the term "finger-fumbler" in Chambers, but couldn't find it...(I may perhaps have missed it)..... but Google tells me
"Noun: finger-fumbler (plural finger-fumblers)
The sign language equivalent of a tongue-twister; a phrase that is very difficult to sign correctly."
I live and learn......
