Kempton Park in Surrey stages racing on two very different surfaces — the Polytrack all-weather oval that operates year-round, and the triangular Jubilee turf course used for the summer Flat programme. Understanding the differences between the two, the horse types that suit each, and the trainer patterns that produce consistent winners at Kempton is essential for any punter who bets regularly on the track.
The Polytrack All-Weather Course
Kempton's Polytrack is one of the most used all-weather surfaces in Britain, producing racing throughout the winter months and on weekday evenings through the Flat season. The surface is a blend of sand, fibres, rubber, and wax that produces consistent conditions regardless of weather — one of its primary appeals as a venue. Going is described as standard or standard to slow rather than the turf descriptions, and the Polytrack rewards a specific type of horse.
Horses who have previously won on Polytrack at Kempton are among the most reliable course form plays in all-weather racing. The surface suits a smooth, balanced action — horses who travel fluidly without excessive knee action tend to perform better than those with a high, extravagant stride. Stamina counts at Kempton's Polytrack. The track is left-handed with a tight home turn, and races over a mile and beyond reward horses who can sustain their effort through the final two furlongs rather than quickening sharply and then emptying.
Last night Water To Wine won the Unibet Novice Stakes at Kempton on the Polytrack — a horse making his all-weather debut after winning on turf at Newbury. His smooth Gosden preparation and Ryan Moore's ability to settle horses on unfamiliar surfaces made the surface switch less of a concern than it might have been with less accomplished connections.
Draw Bias on the Polytrack
Draw bias at Kempton's Polytrack is worth understanding before backing any race. Over the straight five-furlong course, low draws have historically performed better — the inside rail position gives horses a shorter path and reduces the energy expended finding a position. In round-course races over a mile and beyond, the draw is less significant because horses have the opportunity to find their positions through the first furlong before the track compresses into the home straight.
In large fields over sprint distances, checking the draw statistics before committing to a selection is worthwhile. A horse with strong form but a wide draw in a large-field Kempton sprint faces a structural disadvantage that the form alone does not capture.
The Jubilee Turf Course
Kempton's summer turf programme uses the triangular Jubilee course, which is right-handed and flat. The turf course has a different character to the Polytrack entirely — quicker, more conventional, and less specialist in the horses it suits. Form from other flat, right-handed turf tracks translates reasonably well to the Jubilee course, and the draw is less predictive than on the Polytrack because the wider turf track gives horses more room.
Trainer Patterns
John and Thady Gosden, Roger Varian, and Hugo Palmer from Newmarket have strong Kempton records on both surfaces. For the evening all-weather meetings, yards with specific Polytrack expertise — Mark Johnston's former operation, James Tate, and smaller yards with high all-weather strike rates — are worth tracking. The 14-day trainer strike rate remains the primary form indicator at Kempton as at any track.
