Rounds 11 & 12: Knockhill, 27-28 July

The Calders, Heather and Colin, were dominant amid variable weather at Knockhill.

On Saturday Heather stormed to her maiden victory and in doing so became the first woman to win a championship run-off since the great Patsy Burt in 1970. Meanwhile her father Colin confirmed his position of champion-in-waiting with second place.

Heather could only finish third on Sunday, with Colin taking victory. The pair was split by Terry Holmes following a last-run charge.
