Events run under permit from:ForestServiceShield Color

Hey all our valued racers, supporters and friends; Gold Rush is taking some time off! We will have an abbreviated calendar in 2019.

We are taking a break this year and won't be putting on the Summer Challenge or the Gold Rush Challenge and Mother Lode races. After 20 years of promoting Adventure Racing in Northern California we decided we deserved it! We will still hold the Day O and Night O orienteering events. We know that adventure racing on the west coast will remain alive and well with the Expedition Oregon ARWS qualifier and events by Bend Racing and Tahoe Big Blue. We will be back in 2020 with a great new race so stay active and look for us in 2020.

Great Night O on evening of Saturday March 23rd. Map and compass practice at night. Nearly full moon!

In 2018 the Fergusson fire prevented the race from being run. In 2017, team 'Bones ' was first across the line. In 2019 we won't hold the race so start training for 2020. Encourage your friends to race and we can raise the prize purse!

AR History Project...


Adventure Racing History Project

The AR History project will collect information about past AR events. Starting in the late 1970's , Adventure Racing had only a few major events until the sport began to blossom in 2000. We still have the chance to collect the complete history of Adventure Racing. In just a few days, we will provide the link to the AR History Project Site where we can all begin to fill out the history of Adventure racing.

Thanks for your support.
