About the Event

*ALL trails are closed on July 8 from 12 a.m. - 6 p.m. for the Whiterock Ultra. We apologize for any inconvenience.  COME RUN WHITEROCK!

Join us on Saturday, July 8 at the Whiterock Conservancy in Coon Rapids, Iowa, for the fifth running of the Whiterock Ultra! All race-day activities will be held on the trails of the scenic and sprawling Whiterock Conservancy.  Our goal is to raise visibility for the beauty and accessibility of Whiterock and to support its conservancy efforts. **Proceeds from this race will be donated back to Whiterock Conservancy.**




Sometimes, there are weather events beyond our control. (A little rain in the forecast won’t stop us.) But if there is a threat of more severe weather, we are dedicated to ensuring the safety of all participants, volunteers, and spectators. All decisions made by race officials are non negotiable. If we deem the course unsafe because of weather conditions, here’s what you need to know.  Race officials may delay the event, change the route or cancel the race in case of extreme weather or other conditions that may affect the safety and health of participants. We will do everything in our power to hold a safe event. The race can be delayed for a maximum of two hours from start time. If severe weather hasn’t cleared within two hours, the race may be shortened or canceled. The race director in consultation with law enforcement, fire/EMS, Conservancy Staff, and other officials, will monitor the weather and make a decision if any action is necessary.  If the race start of the 50 mile event is delayed more than 2 hours, participants will be entered into the 50Km race starting at 7am.  If the race start of the 50Km event is delayed more than 2 hours the course will be shortened to accommodate a course cut off of 7pm. Aid stations may have little to no support after 5pm so please plan accordingly.  Race officials may decide to shut down or alter the course after the race has started if weather conditions deteriorate and trails are too wet to handle abuse from the race. Runners will be asked to take shelter at the closest aid station or other safe location if weather is severe. If you refuse to take shelter and continue, you do so at your own risk. Aid stations will be unsupported at this time and you will not be eligible for top-finisher awards.  If severe weather alters the event mid race, participants will have their time paused as to when they crossed the River house aid station timing mat. The race will resume 30 minutes after race officials give the all clear. Your time will resume when you check out of the River house aid station by crossing over the timing mat.  Volunteer course marshals will be released from their positions if the race is canceled.  Entry fees are nonrefundable. Proceeds are donated to Whiterock Conservancy and your entry fee has been used to help cover the cost of the event.  Required Gear  If there is excessive rain (>~1”), it is possible that the course may be altered to include some gravel roads as an alternative to the trails. Rain route details are below. In the event that we are moved to gravel roads, athletes will be required to have a safety vest, per the athlete guide that was sent out last week. Weather appropriate rain gear is also recommended.   Rain Route  Alternative rain routes will only be used in the event of excessive rain. This includes a modified Red Loop and Blue Loop. Please pay extra attention to the White Loop, which would be a new addition to the course and run on gravel roads (and one minimum maintenance B road).  Red Loop:  White Loop:  Blue Loop:   50 Mile* runners will run 3 consecutive Red Loops, 1 white loop and 1 blue loop.  50 Km* runners will run 1 red loop, 1 white loop and 1 blue loop.   *Distance is approximate. Safe Locations:  Please familiarize yourself as best you can with your surroundings and know safe locations. The River House, Oak Ridge Campground shower house (Red Loop), Starfield shower house (White Loop) and Garst Lake House (Blue Loop) are the safest locations when inclement weather strikes. If lightning, hail or high winds are present please seek shelter at your nearest location.
