The tennis match between Vicki Nelson and Jean Hepner in 1984 at a tournament in Richmond, Virginia broke many records. It is the longest women’s tennis match ever played, it lasted 6 hours and 31 minutes. It is also the longest tennis match completed in a single day (the longest match ever between John Isner and Nicolas Mahut which lasted more than 11 hours was played in 3 days). Probably the most bizar record Nelson and Hepner broke that day was the longest rally ever played in professional tennis history: 643-shots in 29 minutes!!
