The Pine Island Gravel Odyssey, formerly known as the Gold Rush Gravel Grinder, website details each of the 45-mile, 70-mile, 110-mile, and 210-mile distances on the Gold Rush Gravel Grinder Event website. Rather than try to replicate that here, take a look at the website for more.
The Event Promoter also hosts the Dakota Five-O MTB race and the 28 Below Fat Bike event. Check them out as well.
