Entering its 12th year and the 10th at Interlochen State Park, InterROCKIN is located across the street from the world renowned Interlochen Music Camp. Just 15 minutes from Downtown Traverse City, and with a great campground right there in the state park, this event has a huge following of athletes who bring the entire family up to camp at the park for the event. And you can spend the whole week in Traverse City, as this event is scheduled conveniently at the end of the Traverse City International Cherry Festival.
The out and back run course cuts right through the campground so dozens of campers can cheer you on at the start and end of your run discipline. The swim is in crystal clear Duck Lake. The bike course is the flattest part of the entire Grand Traverse County; the only climb at about mile 4 on the course. Lightly traveled smooth roads make this just a perfect vacation destination event with something for the entire family.

Tri Again Fitness
Due to an increasing amount of athletes entering events they may not be properly trained for, we are asking each athlete to be responsible and honest with his/her ability to complete the distance registering for. Due to safety concerns for everyone involved including you the athlete, but also the support crew volunteers and officials like police, sheriff, fire department, etc. we must instill course cut off times at 4 hrs. Raffle and awards start at 3 hrs and 30 minutes in Olympic distance events and 99% of all athletes are finished by that time. So you must register for the event you will finish under that 4 hour time limit. Being a responsible athlete means if you cannot complete the Olympic distance comfortably under that time we recommend you participate in the sprint event. We encourage you to train for the goal to reach that Olympic distance under the 4 hour time limit. If you do not have a clear idea as to how to achieve that goal we are here to help, please let us know.
An athlete will be informed he/she has reached the 4 hr. cut off, at which time the athlete will acknowledge he/she understands completely and he/she will be brought in off the course by the course coordinator. If the athlete refuses this he/she will be informed that there will not be any support left on the course from that point and he/she must acknowledge this and understand he/she is continuing under those circumstances at which time the athlete will remove the timing chip/strap and give to the course coordinator.
Again an athlete must take the responsibility on as an athlete understanding his/her ability at the time of the event. Knowing that support crew volunteers, as well as other personnel out on courses must be kept in safe conditions as well.
