But a strong performance in Singapore, and some words of wisdom from Isinbayeva, will give her a fighting chance of getting there.
If she does, it will be the culmination of plenty of dedication from at least three members of the Byres family.

"Singapore is a very nice place to be and is an opportunity to see different cultures," she said. "It's very, very hot with a lot of humidity and quite different to England, and it has a nice Olympic village.
