The Blood Sugar Rumbler takes you through some of most beautiful areas of The Lewis and Clark National Forest just North West of Helena Montana. This event supports the Montana Youth Diabetes Alliance and their summer camp scholarship fund to help kids get to summer camp. Riders will have two different ride options to choose from, either the Rumbler for 55 miles or the Bumbler for 26 miles.
The Rumbler includes 5,000+ft of climbing within 55 miles of forest services roads and is geared towards the more advanced gravel rider. The climbs are challenging and somewhat technical yet the down hills are worth it.
The Bumbler is 26 miles of an out and back, rolling dirt road that follows the Prickly Pear Creek through a beautiful canyon. This is a great route for anyone just looking for a fun morning out with friends. Both courses will have aid stations with water, Hammer Nutrition products and food.
