With 52 millimetres of rain falling in the Yarra Valley since Saturday today's planned grass roots trotting races have returned to the harness racing track.

Harness Racing Victoria Stewards have conducted an inspection this morning of the Yarra Valley thoroughbred track.

This inspection revealed that the track is not suitable for racing with surface water present between the 900m and 600m.

As a result races four and seven, which were scheduled to be run on the thoroughbred track, have been transferred to the harness track with the distance amended from 1950m to 2150m. The races remain a standing start with the barrier draw and handicaps unchanged.
