What is the Cascadia Super Gravel?

What is the Cascadia Super Gravel? The CSG is the culmination of seasons upon seasons of backyard explorations, weekend wanderings, and solitudinous escapes. For years the CSG was nothing more than a barstool disquisition between friends, a dream of sharing our own “Secret” expanse of routeways with the world around. Eventually though over the years this thought experiment grew in to something solid, and in 2017 we showed the world what Capitol Forest had to offer. Since then we have only grown. Adding miles, new challenges, and plenty of new riders. The Cascadia Super G is the hardest gravel race you have ever done, and thats the point. 

The race is broken down into three courses, the 30 miles of gravel, the 50 miles of guts, and the 100 miles of grit, all designed to offer a unique experience and difficulties respective to their durations. Racers will be confronted by a course unlike anything that they've experienced, from single track and animal trail to hike-a-bikes, to the ubiquitous grades of Capitol Forest. It will be a day to challenge you, to re-define what you consider gravel, and to remember.

100 Miles of Grit

Test your mettle against the longest course the CSG has ever offered. This race will push your grit over 100 miles and nearly 13,000' of vertical gain, taking racers across the expanse of capitol forest in what will be the largest circumnavigation we've ever attempted. The highs will be high, and the lows will be low, and you’ll all out come out better from it. This is the race for the Legends.

50 Miles of Guts

Not looking for the all day burn? Then Fifty Miles of Guts offers a stunning day in the hills, with enough miles and elevation to ensure a day off earned. If you show up to race, then a race you’ll have, but if riding with your pals is the agenda, well then the 50 may just be what you’re looking for. This is the race for the weekend warriors, the offseason athletes, and everybody in between.

Navigation Guide

Let’s talk direction. While we supply you with a professionally marked course and digital GPX files, it’s important to remember that shit happens, and you always need a bail out plan. In our navigation guide we talk about how to download base maps, GPX files, offline maps, and plot bail out points. While we will have course sweeps, aid stations, and other on course safety and support, you can never be too prepared.

With three course distances embedded within an incredible network of gravel roads, you'll find a balance between epic, challenging and completely doable.  Don't think you can get off the couch after curling your favorite IPA for the last few months and do it.   However,  if you've been riding your bike consistently in preparation you should be able to complete the course.  The course is 90% gravel, ranging from hard, compact gravel, to loose gravel and dirt.  The first and last few miles are on pavement.
