Blackhouse Heidi, a lively candidate for the Great North Run that starts at Newcastle next Saturday, looked in perfect nick for that challenge when she scored a runaway victory at Sunderland on Friday writes John Forbes.

The Harry Williams-trained bitch found a path through first bend trouble that did then odds-on Elwick Glory no favours at all and she ran on powerfully to defeat the favourite by six and a quarter lengths in 39.50, second fastest clock of the year for the 640 metres on Wearside.

Runner-up to Airmount Paco in the Great North Run twelve months ago, the daughter of College Causeway will be fancied to go one better on this form.
