Who's Who at Pendle?

Is Gaynor saying "Does his mother know he's out?"?
More likely Gaynor would be saying "What am I doing at a fell race?" Is this the Gaynor that is even more wonderful at descending than I am. I think that EtU is imagining things if he thinks Gaynor has started doing fell races with particularly challenging descents.

I think it is a young lady who used to speed past us on the track at Wigan many years ago - Lindsey - who I note beat her dad in the race
