In reply to Matt Podd:
Sounds like it would have been exciting for the supporters!
Carol also did a sub-24 solo unsupported BG a month or so ago as prep. She was on crutches in May/June 2019 last I saw.
Looking at the list of peaks for the 24h record, both for the men and the women, there are some historic ones that wouldn't make the grade now. Coombe height for the men is absolutely laughable - there isn't even a ring contour on the map, and barely a cairn on the ground. For the women Calfhow Pike doesn't have it's own contour but about 5m of ascent, whilst Sale How at least has 2 contours around it! Yet Knott Rigg, which does have a defined few contours around, it doesn't count for either!
