TEAM GB star Molly Caudery was left devastated after failing to qualify for the pole vault final.
The 24-year-old was a huge medal hope for Great Britain going into this summer's Olympic Games having established herself as No1 in the world.
However, she failed to clear 4.55m at the Stade de France in what has been described as the "biggest shock" of the track and field events so far.
Caudery broke down in tears following her final attempt while acknowledging the crowd from the mat.
She then told BBC Sport: "It's totally heartbreaking. Not the Olympic experience I was hoping for and I am so sorry for everyone back home.
"I wish I could have done better, but I am going to try learn from this and I will take everything I can from it.

"I felt great, the best shape of my life. I didn't feel too nervous I love a big crowd.
"I don't know why, but it wasn't my day and I'll use this as an experience to learn from it and to try move on.
"Thank you to everyone for their support."
Caudery set a British record of 4.92m in June and is the reigning World Indoor Athletics pole vault champion.

Former Team GB 400m runner Katharine Merry described her exit as one of the "biggest shocks" of the games.
She told BBC Radio 5 Live: "Nobody is going to believe this. This is the biggest shock in the track and field of this Olympics.
"Molly Caudery has gone over a height of 4.92m [this season] - 4cm higher than anyone else in the world.
"She decided to come in at a opening height of 4.55m. In her pool nobody else entered at that height, everyone else came in at an earlier height."
Holly Bradshaw also failed to qualify for the final after falling on her third attempt.
While both appeared inconsolable, it was all smiles for Amber Anning, who won her 400m heat in a comfortable 49.68.
But Victoria Ohuruogu will have to progress through the reprchage after finishing fourth in her heat.
