The racing community is reeling after jockey Simone Montgomerie died following a race fall during the Darwin Cup meeting.

Champion jockey Nash Rawiller said he had never left a racecourse feeling so sad and numb, while trainer Lee Freedman said the whole racing industry feels the pain.

From a noted racing family, Montgomerie, 26, was thrown from her mount Riahgrand when she was coming down the home straight in the sixth race of the day at Darwin Racecourse on Monday.

The mother of two tumbled off her horse and was trampled by the rest of the pack.

Two doctors treated her at the scene, but Ms Montgomerie passed away shortly after arriving at Royal Darwin Hospital.
