Arrowhead Winter Ultra

Following are 2010 event rules and critical information. Please note that race rules may overlap with State rules; therefore, repetition means IMPORTANT--

  1. Sign-in at the gear check on Saturday, Jan. 30 from 8am to 4pm in International Falls, at the BlogBackus Auditorium (an old school building, 900 5th Street) near the center of the city. A second gear check will be held on Sunday morning from 6am to 2:30 pm for those who cannot make it on Saturday. Please try to come early on Saturday because we have too many entrants to check on Sunday.
  2. A pre-race meeting will be held in International Falls, Sunday at 3:30 pm Jan. 31, 2010 at the VFW club on Hwy 53 in the center of the city. At 5pm Sunday the VFW will serve a spaghetti dinner at a cost of US 8.00 per person. Volunteers and friends are welcome.
  3. The race starts Monday, Feb. 1, 2010 at 7am, in the Kerry Arena at the center of the City of International Falls near the Arrowhead/Blue Ox trailhead behind the Outdoorsman. (You may leave your car at the hotel. We will work out a means to shuttle people and gear between the finish and start).
  4. No outside help from anyone except other racers. This means that there are no support crews of any kind and no rides/tows accepted from snowmobilers, nor other vehicles. If you take a ride, you are forfeiting your right to finish the race and you must contact race officials to notify us when/where you are dropping out of the race. However, participants are encouraged to help each other. The buddy system is a good way to do this race.
  5. No littering. (and no stashes). This should be obvious but it is so important to us that we thought we should put it in the rules. Leave no trace. Make use of sanitation facilities provided along the trail. There is an outhouse next to each of 9 trail shelters along the trail. Bring your own t.p.
  6. If you leave the race course for some reason, you must re-enter the course exactly where you left it or notify race officials that you are dropping out as soon as is feasible. Short-cutting the course is not allowed and may be grounds for disqualification or time docking after the race is over, at the discretion of the Race Director.
  7. The Gateway General Store on Hwy 53 is the first required checkpoint. Note: racers are allowed to purchase food, goods and services here and at any official checkpoint.
  8. No road riding, running or skiing except in places where the road is part of the race course. Racers may cut across Elephant Lake to reach the MelGeorge's resort (2nd checkpoint) Cedar cabin and you may cross or ride on the road to return to the Arrowhead State Trail. You must check in officially at the Melgeorges checkpoint cabin before going to the restaurant or taking a room at the resort. The last person to the Melgeorges checkpoint wins the Myrtle the Turtle award. Racers are allowed to rent their own motel room or cabin at Melgeorges. This year, we also have a 2nd Maple cabin for volunteer snowmobilers to take breaks/nap.
  9. The third checkpoint is the Wakemup tipi off the trail near the Crescent Bar & Grill Olson Road, Cook MN about half way between Melgeorge's and the finish line at Fortune Bay Casino.
  10. Snow machines and dog sleds have right of way. You must pull to the right side of the trail and let them pass. Stop at all intersections and obey traffic rules.
  11. All racers are expected to carry or tow a minimum of 15 lbs. of gear (not including the sled, bike, skis, nor water) at all times and must finish with at least 1 day or 3000 calories of food and 8oz. of fuel. Racers may share gear and assist each other; however, each participant must have their own mandatory gear at all times.

    • Drop bags must be clearly labeled with racers name, filled with your supplies and secured shut.
    • You can share drop bags with another racer to limit waste.

  12. You may pick your race category the morning of the race based on weather conditions, etc. You must stay with it and finish in the mode in which you started (i.e., if you start on bike, you must finish on bike). Walkers/runners may use snowshoes in the foot category; however, they are not required to do so. If you use snowshoes, you must carry/tow them all the way to the finish.

There is no formal party, but we have a hospality room and suites overlooking the finish line, near the pool for volunteers and spectators. There is also a secure room in the basement near the pool to put your bikes/sleds and gear).
  14. Race Directors reserve the right to change the rules at any time. Race Officials may pull participants from the event, including volunteers and spectators, in the interest of law, safety and fairness or for any reason deemed appropriate by the Arrowhead officials.
