Here is a little description from the Bike 29 blog about the course;
"New folks will want to know that you can expect be on your bike between 1.5-4 hours depending on how quick/fit you are. Or 2-5 depending on the course I set. A lot of that has to do with the weather and snowmelt, but at this rate, adventure is a word you should be prepared to deal with. The course has traditionally been around 30 miles with 3000ft of elevation gain."
So there you go- adventure! I like adventure. If you do to, click on the link under the image and go register now.
