Runner & Volunteer Surveys

Now that we've all had a month to reflect on this year's run, we'd like to invite everyone who participated this year to share their feedback.

These questionnaires help us improve and better serve your needs and the ultrarunning community. The organizing committee uses this survey, every year, to make Hardrock better for you!
