Claxton could have just 12 days between Moscow and Melbourne

Claxton is the only British athlete who is competing in both the World Indoors and the forthcoming Commonwealth Games.

A depleted GB team for the three-day Moscow event includes Karen Harewood, who takes on 800m legend Maria Mutola.

Also competing are world record holders Yelena Isinbayeva (women's pole vault) and Kenenisa Bekele (men's 3,000m).
