The BBAR is run over 50, 100 miles and 12 hours for men. The women’s version is 25, 50 and 100 miles and Beryl did not need the 12 hour for her BBAR. In 1967 the BBAR was just the BBAR but since 1999 there have been 2 distance and 3 distance versions. The 3 distance BBAR is the same as the old one. The 2 distance version counts only the 2 shorter distances: 25 and 50 miles for women, 50 and 100 miles for men.

Beryl’s record, which still stands in spite of the advent of carbon fibre bikes, disk wheels, skin suits, aero helmets and scientific training and nutrition is 277.25 miles, not 277.52. All the other competition records she set have since fallen to better equipped riders, but none of them before the 1990s.
