The best eight out of ten placings in the series will count in the final tally (dropping the two races with the fewest points). Riders must race in at least 6 races for the overall series. Series prizes will be awarded at the series end party. There will be no BAR points for the series, only the individual races.

Points will be rewarded to the top 30 placings according to this schedule. Series scoring follows this criteria and team scoring follows this criteria. Reminder: only your top 8 results count and a minimum of 6 race results needed to have a series overall final ranking. Point totals and point standings will be handled by Athletepath and we'll link to them each week in the updates.

Podiums/Leaders Jersey

A short podium ceremony will follow each finish at the races. A GPET leaders jersey provided by Castelli will be awarded to the leader of select categories during a short podium ceremony after their race. The points leader of each category is required to wear their leader's jersey while they maintain their lead.

Field Limits

To ensure a high level of quality racing, fields will be limited to 75 racers per category

Series standings

Points for the series will be tracked at Athletepath. They will continue to be updated after each race. We are not doing a points percentage transfer when upgraded.

Heiser Farms: Sunny day in the pumpkin patch

TR0C5163 Heiser Farms hosted a great day of racing in the warm sun, despite a week of heavy rains prior to the event. Results are up at athletepath and photos are available (1, 2)

Ninkrossi: Mud, hills, and the big N

Ninkrossi N Ninkrossi was a wet, muddy, but fun affair in Washougal, Wa. The hilly course provided a challenge to many pushing through the muddy ascents and fast descents of the course. Facebook event page is here, results are at Athletepath, and photos are available (1, 2, 3)

Zaandercross: Sand, everywhere

Zaandercross Zaandercross is known for its long sand sections, stairs, and general difficult course and this year didn't disappoint with the addition of light rain. Results are on Athletepath and photos are available (1, 2, 3) and the event's facebook page is here.

Hood River Double Cross: Hot times on the river

DSC_0682 Hood River High School provided a nice venue with varied terrain including singletrack fast downhills, sandy sections and grass hill climbs. It was a scorcher of a race, taking place in the middle of a heat wave before Fall's rains. Results are up at Athletepath and photos are available (1, 2)

Het Meer: Storming the beach

TR0C3702 Het Meer's famous beach provided ample entertainment among the beauty of Vancouver Lake Park. The weather was warm and dry, the sand was ridable and mostly fast thanks to recent rains, and the rest of the course was easy to manage. There are some photos from the day (1, 2, 3, 4, 5) and results are up at Athletepath. More photos and videos from the day are available on the Facebook event page for Het Meer.

David Douglas #1: Starting the season in the red zone

TR0C2670 A scorching hot day at the park kicked off the GPET series and the OBRA cyclocross season. The races were fast, exhausting, but recent rains cut the dust and made conditions just about perfect. There are some photos from the day and results are up at Athletepath. Thanks everyone for coming out and making the kick-off event so great!
