Britain is down to run in the women's 4x400m and short medley. I would imagine the 4x400m will be Cox-Sanders-Ohuruogu-Shakes-Drayton (not neccassarily in that order). The medley might have Abi on a 200m leg and Simpson on the 800m, but that still leaves a 200m and 400m leg. Any idea who they might be?
