So many of those girls have been working hard this winter to try and stay injury free. I was on a train journey with Emily Diamond and we had a long chat about her career and how she is progressing and she had a good solid winter. I am so pleased for the women.
It slipped under my radar there but bronze in the 4x400m means that Christine Ohuruogu ends her Olympic career with medals at three Games.
A gold, silver and a bronze.

Men's 4x400m relay
The final event on the track, as is tradition, is the men's 4x400m relay.
No Great Britain team. If you missed why, they were disqualified after winning their heat because Matt Hudson-Smith was ruled to have had part of his foot out of the takeover zone when he began running.
British Athletics said it was "hugely disappointed" and confident the team would have won a medal in the final.
The appeal was rejected because video evidence was inconclusive, meaning the decision of the referee must be upheld.
GB take bronze
