2012 NAS Grosse Ile Duathlon:

  • Grosse Ile is an island at the south end of the Detroit River and north end of Lake Erie.
  • With Canada on one side and Trenton or Riverview on the other depending on what end of the island you are on, it has been the home to the Grosse Ile duathlon in some form since the early 90's.
  • Originally hosted by Mr. Gene Edwards on the opposite side of the island it now finds its home at a great venue in the airport.
  • Course Information:

    5k Run, 25k Bike, 5k Run:
  • The run course is basically the same just an official 5k now. Super flat, fast and closed actually on the airport property, no worries from cars as it is all enclosed on the grounds.
  • The bike course is what this event is all about circling the island on a semi rolling course with views of the river on both sides. A few short, small hills that will keep everyone honest out there but certainly nothing that requires you to get out of the saddle or anything like that.
  • Repeat the 5k run on the closed airport grounds.
