A couple other possibilities,
Long distance cyclist Eileen Sheridan, who broke all the long distance and point to point records the English cycling organization had listed for women in the 1950's. And made a good run at breaking the 1000 mile record outright, falling a bit over 2 hours short of the mens record. Her record for 1000 miles stood for 48 years, and five of the place to place record still stand.

Or Beryl Burton, who won nearly everything, and set a record for 12 hours that still stands,277.25 miles and at the time was
the record, being farther than the mens record, which was set the same day.
