It was a battle of the Bunbury boys at the eighth and final round of the 2019 XCO State Series on Sunday.

More than 150 of the State’s best cross-country riders descended on the classic Pile Road mountain bike trails for the event in a last bid to secure as many series points as possible.

In A-grade men, series leader Rowan Brown was not firing on all cylinders, which paved the way for a South West domination, with Bunbury’s Sam Reeves and Blake Seroka finishing first and third in a hard-fought race.

A leading group of four went out on the last lap, but Reeves was the first to emerge from the forest and finished eight seconds clear of Jon Gregg in second and 24 seconds clear of Seroka.

Fellow Bunbury rider Kallen Williams came in fourth while Brown recovered to finished fifth.

In the A-grade female race, Perth’s Sarah Tucknott put in a dominant performance to finish three minutes in front of second-place rider Tracey Chapman with Stefanie Van Amerongen a further 17 seconds back.

Dunsborough’s Sarah McLachlan was the best-performing South West rider and claimed fourth place 51/2 minutes off the pace.

Riders will now prepare for the upcoming State Championships to be held at the Linga Longa Bike Park (near the Nannup State Forest) on September 15.
