• This week’s racing calendar features a unique form of motorsport, Trials. It’s not about speed but the rider’s control as they negotiate various obstacles.   The goal is earning the least amount of penalty points when a rider completes what ever course they are on. Put a foot on the ground or get stopped and a point is added, so the one with the lowest points is the winner. The Boreal Ridge Trials will be staged at the Boreal Ski Resort, just west of Donner Summit on I-80. Beginners and vintage bikes competing on Saturday starting at 10 a.m.
