YORKSHIRE'S involvement in the FIM World Trials Championship is normally confined to the long-standing indoor event at Sheffield Arena in January.

However, all that changes this weekend when the Wulfsport Oset World Trial Great British Grand Prix takes place in Bradford.

The course at Parkwood, Tong, for the penultimate of the eight global rounds has been set by former GP trals winner and current enduro star Graham Jarvis, with the sections being described as "carefully planned" and "British-style".

One thing is for certain – the muddy banks will be much more difficult if it rains as the world summer round returns to Yorkshire, billed as the home of motorcycle trials, after a 23-year absence.

Local interest is provided by Cookridge's James Dabill, who has been on the podium in a British round before, but he will be facing last weekend's Belgium Trial GP winner Toni Bou, who recovered after a poor first lap, runner-up Adam Raga and third-placed Albert Cabestany (Sherco).

Other strong opposition comes from Dabill's Vertigo team-mate Jeroni Fajardo and Repsol Honda duo Takahisa Fujinami and Jaime Busto.

Also competing are the world’s best women riders, including defending champion Emma Bristow.

Bou is seeking a record-breaking tenth consecutive world outdoor title, and his victory in the Belgian single-day event stretched his championship lead over arch-rival Raga to 23 points.

Raga, who has won just one single-day event this year, needs to win on both days at Tong to stand a chance of catching Bou in the final round in Italy.

However, history is against him as Bou has won eight successive British rounds, stretching back to 2008.

In Trial2, which is the largest class with 29 riders, it is odds-on that Yorkshireman Jack Price (Gas Gas) as he is 40 points clear of second-placed Iwan Roberts (Beta), who is just six ahead of Spaniard Arnau Farre (Gas Gas).

Dan Peace (Gas Gas) and Gael Chatagno (Beta) are locked together on 123 points, and are still in with a shout of a season-end podium finish.

Jack Peace (Gas Gas) has already won the Trial125 crown, and will be joined by 11 other British riders in a healthy total of 18.

The event starts tomorrow (Friday) with practice, with the Grand Prix itself being held on Saturday and Sunday.

Admission and camping is available on the gate each day, and they open at 7.30am, with the first riders departing at about 9.15am, with the presentation of awards at about 3.45pm.
