She was always in contention throughout the race, but in the final 100m as her rivals pulled away, there was no fight back from the Glasgow swimmer in the latter stages.

Cooke, the world bronze medallist last year, clocked a disappointing 8:29.37, just under a second away from her heat time and lifetime best.

Cooke vowed to bounce back from her disappointing games and admitted her below-par performances were “really, really upsetting”.

"It's just really hard when you know how much work you've put in. To not compete how I expected and not get what I feel I deserved at the Olympics is just really, really upsetting.

"It's going to be a lot tougher to get over this because it's an Olympic Games and they only come round every four years. I think it's going to take me a while but I'm sure I'll bounce back.

"I wasn't overly nervous, it's just such a big occasion and you just want to swim your best."

Although Rebecca will be disappointed not to have won any medals in Athens, City of Glasgow swimmers, coaches and parents congratulate Rebecca on reaching two finals in the biggest Swim Meet of them all!
