Latest track conditions are noted in the top line (just above the race times) with rail position and weather conditions

How we get the track rating

To ensure that there is a consistent method of measuring the ground conditions and being able to compare tracks nationally and also throughout the entire racing season all race tracks use a penetrometer.
As per NZTR The penetration recorded by the penetrometer is the depth that the horses hoof is expected to rotate into the soil.

In its basic form, a penetrometer is a steel rod which has a standard weight dropped from a standard height to drive it in to the ground. The ground penetration is measured and converted to a standard reading. Softer ground will give higher penetration than harder ground. Standards for its use are provided by the NZRB

At Trentham, three penetrometer readings are done every 100m from the 100 to the 600m mark, then every 200m from the 800m to the 1400m along the racing surface. The readings are taken 1.5m, 3.0m and 4.5m out from the rail (where the horses will likely run) The readings are then converted to a recognised scale from 1 (Fast, hard and dry) through to 11 (Heavy, very soft and wet).

While they can be done at any time, penetrometer readings are required to be done and reported to the Racing Bureau every morning from Nominations morning for the week prior and also the morning of a race meeting to the bureau and the RIU (Tuesday to Saturday for a Saturday meeting). There is also a requirement to do a reading on the afternoon of the day before the raceday which is also reported to the bureau (Friday afternoon for a Saturday meeting).

When irrigating, the track staff may also use a "second drop" of the penetrometer to check that  the soil moisture profile is ideal and adjust watering rates accordingingly. 

Our aim at Trentham is to have as close to a "Good 3" racing surface on the afternoon of a race meeting as possible. Realistically, for meetings that fall out of the Spring and Summer period, rainfall, heavy dews, a raised water table, soil saturation, lack of suitable drying conditions, slower drainage etc are likely to mean conditions closer to the "heavy" end of the scale for Autumn and Winter meetings.

Scale Rating Comment Penetrometer Band
1 Fast A dry hard track 0.5 - 1.9
2 Good A firm track 2.0 - 2.2
3 Good Ideal track with some give 2.3 - 2.5
4 Dead Track with give, better side of genuine dead 2.6 - 2.8
5 Dead Genuine dead 2.9 - 3.2
6 Dead Significant amount of give, worse side of genuine dead 3.3 - 3.5
7 Slow A mildly affected track, better side of genuine slow 3.6 - 3.8
8 Slow Genuine slow 3.9 - 4.2
9 Slow Rain affected, worse side of genuine slow 4.3 - 4.5
10 Heavy Genuine Heavy 4.6 - 5.5
11 Heavy Very soft and wet, heaviest category 5.6 +
