Details Starting in International Falls, Minnesota, the Arrowhead trail heads southwest for 10 miles before heading west and eventually southwest for the majority of the route. The Arrowhead Trail starts out relatively flat for the first 30 miles before the route starts to take on short but difficult climbs. The route travels through the heart of the Kabetogama State Forest, over frozen streams, marsh land, deep timber, and desolate track. The cold conditions in the winter usually make this route much more attainable than in the summer months.


- 2010 was an exciting year with Jeff Oatley first to finish, just seconds before Pete Bassinger and David Pramann. Janice Tower took the woman’s win and coures record that year with a time of 20h 46m.
- In 2011 it was the Jeff Oatley and the Heather Best show as they both took home course records of 15h 50m and 20h 14m respectively.
- 2012 was another exciting finish with Kevin Breitenbach beating out Tim Berntson by a wheels width. Eszter Horanyi broke the women’s course record by 2 hours with a time of 18h 18m.
- 2013 was a year to remember with the leaders beating out the soft and snowy conditions while the middle and back of the pack were slowed down to a crawl. Todd McFadden beat out Jeff Oatley by 30 minutes with blazing fast time of 14h 20m and a new and current course record.
- 2014 historically had some of the coldest conditions and it’s proved to be one of the slowest years on record. 84 racers participated, 54 of them failed to complete the race while only 30 finished. The Petervary’s took the wins with Jay finishing in 20h 11m, and Tracy coming in at 5th overall with a time of 27h 22m.
