Race Day

With weather forecasts anticipating temperatures in the low-80′s with possibly humid conditions during event weekend, DCT organizers are taking extra precautions and urging the athletes to do the same.  Enhancements to address the heat include:


  • AMPLE FLUIDS ON THE BIKE COURSES.  Every bike bottle handout station will have 1.5 to 2.0 bottles available per participant.  Sprint participants have TWO opportunities for fluids on the 18 mile course (start and halfway point).  Half Iron participants have SIX opportunities for fluids on the 56 mile course.


  • AMPLE FLUIDS ON THE RUN COURSES.  Every rest station on the run will have 3-4 cups of fluids per participant.  There will be THREE opportunities for fluids on the Sprint run course (start, mile 1.5 and mile 2.2).  There will be TEN opportunities for fluids on the Half Iron run course (start, miles 1.5, 3.1, 4.2, 5.5, 7.1, 8.1, 9.7, 10.7 and 12.3).  On average, there will be water stations every 1.2 miles.


  • ICE, ICE BABY!  In addition to the fluids, every rest station on the run will offer cups of ice to the participants. 


  • GET HOSED!  There will be one sprinkler on the Sprint run course and at least 2-3 sprinklers on the Half Iron run course, including an industrial Misting System at mile 12 on Sunny Point Road.


  • TAKE A COLD BATH…  There will be 100-gallon immersion tanks at EVERY REST STATION ON THE RUN.  Participants suffering from the heat are encouraged to dunk their upper bodies into these baths in order to cool off.  There will also be a 1,000-gallon portable pool at the finish for athletes to cool off in when they reach the finish line. 


  • MISTING WANDS.  There will be at least 2 elevated shower-style misting wands that participants may pass under when they finish.


  • EXCESS FLUIDS AT FINISH.  There will be 4,000+ bottles of water at the finish area for participants and spectators.  There will also be soda and beer for the crowds.


Organizers are asking participants to take extra precautions as well.  They are urged to:


  • Wear lighter colored and moisture-wicking clothing
  • Arrive well-hydrated at the starting line
  • Place their personal safety over their pace. 
  • Take every opportunity to take in more fluids on the courses
  • Drink GATORADE in addition to water to replace electrolytes and avoid a condition known as hyponatremia which can result from over-consumption of water


Personal safety takes the joint effort of both organizers and participants.  We’ll see you this weekend!



Race Day

Organizers have been working with the Door County Sheriff’s Department and Sturgeon Bay Police Department for several months to establish road closures and staffing needs to safely accommodate the event. According to Race Director Sean Ryan, “Great care was taken during course design to minimize disruption to residents and visitors in the county.”   None of the routes for the event cross highways 42 or 57.  Residents along the course routes are asked to use caution when leaving and returning to their driveways on race weekend to avoid collisions.  Printed maps and a complete list of road disruptions are available at the Sturgeon Bay YMCA.

On Sunday during the Half Iron event, the County Sheriff’s Department will close County G/Horseshoe Bay Road southbound at Highway 42 from approximately 11 am until 3 pm.  In addition, the section of Horseshoe Bay Road that goes down the hill from County G to Murphy Park will be closed from approximately Noon until 4 pm.  Inbound spectator traffic is advised to parallel park on the east side of County G and catch a shuttle ride or walk down the hill during these hours.  Inbound local traffic may take South Trail to residences, Egg Harbor Beach and The Alpine Resort.  Outbound local traffic and departing participants are advised to depart NORTHBOUND on Horseshoe Bay Road, taking South Trail at the five corners intersection to Highway 42 while the events are in progress on both days.
