MultiSport 101
4:00pm day before race, located in transition area..

H20 Overdrive is our official Multi-Sport 101 partner. You want something that works without all the hype this is it folks. You are going to spend money on hydration drinks you should spend it on something that not only works but is great for the body!!
We have been told by many athletes from across the country that our 101 is the best anywhere. As far as we know we started it back in 2003. 2 years later a few others started popping up, and now most bigger, or shall we say more experienced race directors host them. What makes a great 101 is the experience a race director has not only with the race but most importantly in multi-sport. Kenny has been racing since 1987 along with an exercise science and coaching background he is one of the most qualified out there. Our goal with the 101 from day one has been to go through the entire event start to finish for the newbies, the beginners, the less experienced athletes. To try and calm down those butterflies as much as possible. Along with the information on the race the Race Director will give you dozens of racing and training tips along the way and answer any question you may have as well. Classes range from an hour to 2 hours depending on size and how many questions there are. If you are new to Multi-Sport it is Highly Recommended you attned this class.

Course Info
This event had over 650 athletes from 21 states registered in 2009. The swim is in the crystal clear Duck lake with an in the water start. The bike is pretty much the flattest road in the county with one small climb on the way out, and is tree lined the entire way. Back county roads are lightly traveled to the point athletes have told us they have counted less than 20 cars back there. The run depending on Olympic or sprint depends on what you get for your money. You want flat as a pancake fast out and back or "the hill" that greets Olympic distance athletes as they make the turn for their final 4 tenths before the turnaround point. You run through the cheering fans in the campground on the way out and back in before the excellent finish.
Swim: 500m/1500m
500m / 1500m / 1.2Mi / 2.4Mi - Duck lake is a crystal clear lake with few weeds. The water temp has been as low as 68 and as high as 80throughout the years. You will swim a triangle course for Olympic distance and rectangle for sprint athletes. An in the water start at the last park swim area buoy. Wave starts will be postedon Saturday at Packet Pickup/registration.
Traverse City Swim Club Open Water Challenge Information coming soon, proceeds from this swim event go to supporting the Travese City Swim Club. Come on out Saturday morning for a nice, safe open water swim athletes.

Inter-Rockin Bike Map
20k or 40k - You will exit the transition area straight down the park road then merge onto the pedestrian path for park entry and exit onto 137. There is no need to fly here you can fly when you get out of the park. You will NOT use the park entry/exit that you drove into the park. You will head down just past the Interlochen camp crossing and parking area to a Left turn on Diamond park road and from that point you can fly. Making another left onto Cinder to your turnaround points and back. The short climb isjust past your Left on Cinder/
12TRI: 56/112mi bike
Remember this is an open course! You will be sharing the road with vehicular traffic. Use caution at all times. It will be your responsibility to print maps, and know the courses. It is the athlete's responsibility to know and understand the courses. Helmets are a must. No helmet - no race. MP3 players on the bike course are an automatic disqualification. Due to a few athletes actions in the past during an event we are making you aware not only in this event but ALL events whether hosted by us or any other event management company YOU MUST OBEY ALL OFFICIALS and EMERGENCY VEHICLES on the course AT ALL TIMES!! The bottom line here is your race is not more important than an EMERGENCY or OFFICIAL on the course.In the event of an emergency you MUST obey officials requests, and you MUST STOP and pull off the road for any and all EMERGENCY VEHICLES to get by.This is not only to ensure the emergency vehicles can proceed, it is for your safety as well. Any athlete that does not adhere to this rule will be disqualified and will not race in a 3 d event for the rest of the year. This to us is common sense and should not have ever came to this point.
Run: 3.6mi/13.1mi
Inter-Rockin Run/Transition Map

Relays
At registration you will receive ONE bib number and ONE chip/strap. The bib number goes on the runner as that is who will be crossing the finish line. All relay members must be body marked with that number. The Chip/Strap will be securely fastened around the person competing in the first discipline. There will be a designated spot for All Relays at one of the entry/exit points in the transition area marked RELAYS. All staging and chip/strap exchanging is to be done at this point. Not on the course. The Chip/Strap must be securely fastened to each athletes ankle, do not grab it and go, do not put it on the wrist. Upon finishing it is the last athletes responsibility to return that chip/strap at the finish line. (one athlete may do more than one discipline)
Transition Area
Open at 6:00am closes at 7:45am. No Friends or Family members allowed in the transition area for any reason.The race director and race officials will close the transition area 30-45 minutes before race start to ensure all athletes are at starting lines for mandatory course meetings and announcements. Once the transition area is closed you will not be permitted back in before the race starts. Family members will not be premitted in for any reason. In the event of inclement weather it is recommended you have warm, dry clothing outside the transition area to put on following your finish due to other athletes still being on the bike course. Thank you for your cooperation in following these rules.
You must rack according to your race number based on sequence placed at end of row. Please remember racks will hold 7 bikes racking with seat tip on support bar. Please be courteous to fellow athletes to ensure there is space for 7. Any athletes removing gear from transition areas before the announcer or race director has officially opened the transition area will be DISQUALIFIED from the race! No questions asked, your race number will be taken down and you will be disqualified. The transitionarea is closed until all athletes are off the bike course. Sprint athletes this goes for you as well, you must wait until all the athletes are off the course and race officials open the transition area. All athletes deserve a clear transition. There will be an aid station at the run in/out chute with water and electrolyte replacement. Athletes wearing their own chips, PLEASE remove your chips before re-entering the transition area and exiting again. This can cause a timing error. Run in/out and Bike in/out chutes are clearly marked on the large structures at either end, it is your responsibility to go the right direction.
Race Tips
A hugely popular event and highly competitive, meaning no free awards here. Waves for the swim will be 80-100 athletes, starting in the water at waste deep, so get out there and get a good spot for a good start. A good swim and transition helps here as you have to make your way past Interlochen music camp before you can really start hammering on the bike. So I would waste no time doing that. Then when you make your left past the camp you can drop the hammer. Not much traffic and not much of anything else out there so start picking people off. We have not had issues with weather or winds here to much, most of the courses are pine tree lined the entire way. You will have to slow a bit going past the Interlochen music camp again and then more when getting into the state park for the transition area. It is very motivating heading out on the run going through the south camp ground with hundreds of campers in there cheering you on and the fresh smell of bacon on the fire. LOL Then you head out on a flat as a pancake part asphalt part gravel road. Your out and back it on this road, mostly tree lined, but you can surely use everyone out there as motivation to keep you going. Then I think everyone runs their fastest the last 200m cutting back through the camp ground again to a short jaunt through a tree section before popping out in the finish chute.
