Yelena Isibayeva

During the indoor season, Isinbayeva set her twenty-first world record, clearing 4.95 metres on 16 February 2008 in Donetsk, Ukraine. A few weeks later, in Valencia, Spain, Isinbayeva won the World Indoor Championships over Jennifer Stuczynski. Both vaulters achieved the same height, with Isinbayeva winning by virtue of fewer unsuccessful attempts.[2]

On July 11, at her first competition of the season, Rome's Golden Gala, Isinbayeva broke her own world record, clearing 5.03 metres. This was her first world record outdoors since the 2005 World Championships. Isinbayeva stated that she had tried so many times at 5.02 metres and was still unsuccessful, her coach told her to change something and so she attempted 5.03 metres.[3] This record came just as people began to speculate her fall from the top of pole vaulting, as American Jennifer Stuczynski cleared 4.92 metres at the American Olympic Trials. Isinbayeva stated that this motivated her to maintain her reputation as the world's greatest female pole vaulter. A few weeks later, at the Aviva London Grand Prix, Isinbayeva and Stuczynski competed together for the first time of the outdoor season. Isinbayeva won the competition, with Stuczynski finishing second. Both attempted a new world record of 5.04 metres. Isinbayeva was tantalizingly close on her final attempt, with the bar falling only after Isinbayeva had landed on the mat.[4]

Isinbayeva broke her 19-day old world record on July 29, in Monte-Carlo, Monaco. She cleared 5.04 metres, her twenty-third world record, on her final attempt.[5]
At the 2008 Summer Olympics in Beijing on August 18, she prolonged her Olympic Title, by clearing 5.05m, her 24th world record.[6]
