  • 7.8 miles over very hilly terrain. Racers start in heats of 25  (every 30 seconds) according to our scientific seeding procedure.
  • Seeding is based on your estimated 10K ROAD RACE PACE. You will provide your estimated pace during registration. 


  • We offer an early start option for those who may need a little more time completing the race. You will start one (1) hour early. Water stations and course support will be present. 
  • This option allows all runners to finish the race and be able to enjoy the post race refreshments and awards ceremony.
  • Runners starting early are still eligible for awards.
  • This option is NOT available for faster runners simply looking to start early to avoid the joys of running in the crowd. 


  • Pere Marquette State Park Lodge offers special rooms rates for Friday and/or Saturday night. Simply call the lodge and ask for the Metro Tri Club room block rate. 

  • There are also many fine B&B's in the Alton and Grafton area.
