On the last day of qualification for the London Games yesterday, Sinimole clocked 4:10.72s in Lapinlahti but it was not enough to book her place in the London Games as the Olympic 'B' standard qualification mark stood at 4:08.90s.
According to information received here, Assefa Meskerem of Ethopia (4:09.51s) topped the race ahead of Sinimole, while Finland's Johanna Lehtinen (4:15.27s) finished third.
Sinimole also failed to make the cut for London at the Folksam Sollentuna Grand Prix in Stockholm, Sweden last week, where she finished a disappointing seventh in the women's 1500m with a timing of 4:13.91s.
