Sorting through a box of charity donations, I came across an undated booklet published by the BBC called Broadcasting in the West. 'West' in this case seemed to mean pretty much anywhere west of Southampton, but as I browsed through it I spotted this in the section on sports programming, which also featured some pictures taken during the 1948 Olympic regatta at Torquay, so all the indications are that the booklet dates to late 1948 or early 1949*:

Amazingly, it seems that all the above effort produced just five minutes of 'Summary of the Jersey Road Race', broadcast at 6.15pm on the Western region of the Home Service only, although it's possible that they may also have fed reports into other national and regional sports bulletins.
