McKiernan and McCambridge on the one road with Sonia

SONIA O’SULLIVAN, fresh from her victory on the track in California last weekend, returns to the road tomorrow when she lines up for the 5k at Balmoral.

She will be joined by Ireland’s second fastest indoor 3,000m runner, Maria McCambridge.

Catherina McKiernan is also set to renew rivalry with the Olympic silver medallist, but, while she was a clear winner in the Great BUPA Ireland run in the Phoenix Park a month ago, she may find the 5k too sharp.
