We will be using Ultra Signup to handle race registration again this year. After billing via Ultra Signup, there will be NO refunds, exchanges or credits given. NO exceptions! If there is an error in billing, contact Ultra Signup. Class changes may be made after registration with Ultra Signup is complete with a $35.00 fee, so be sure you enter into the proper age and class the first time.
In the event that a natural disaster (i.e. forest fire) causes the cancellation of the Lost Sierra Endurance run, there will be no refunds issued. All pre-registered/pre-paid riders will be given priority in registering for the following year.
All net proceeds from this event go directly to the Sierra Buttes Trail Stewardship trail maintenance program.
