Мичиганның "Lumberjack 100" тау велосипеді марафоны

The Lumberjack 100 is an ultra endurance mountain bike race held the 3rd Saturday in June at Michigan's Big M Cross Country Ski and Mountain Bike Trail in the Manistee National Forest. The race is a 100 mile mountain bike marathon and is part of the National Ultra Endurance Series. The race course consists of three 33.33 mile laps in the Udell Hills area and crosses the North Country National Scenic Trail twice per lap. The course contains over 8,000 feet of climbing and is 80% single track. Due to venue limitations, only 450 racers are allowed to participate.

In the 2016 edition of the race, Kaitlyn Patterson (Team OAM) had a thirty second lead after the first lap; by the final lap Patterson had extended the lead to more than 20 minutes over runner up Mari Chandler (Team Adventure). In the men's event, Brian Schworm (Think Green VO2) finished four minutes ahead of runner up Alex Vanias (Team OAM), and five minutes ahead of Bradley White (UnitedHealthcare Pro Cycling). The race marked the fifth event in the NUE Series. In unseasonably cold conditions, Brian Schworm (Green's Toyota) and Mari Chandler (Dart Nuun / Tecnu Racing) won the men's and women's open races, respectively.

2014 marked the 10th anniversary of the Lumberjack 100. To mark the occasion, the direction of the race course was reversed. The Women's Open winner Danielle Musto led from the start line, whereas the Men's Open winner, Christian Tanguy, broke away from the competition eight miles before the finish line.

Following a slow spring thaw, the 2013 event featured a dry, sandy course and temperature highs in the mid 70s (degrees F). The men's open race was decided in a sprint between the three podium winners, Barry Wicks, Michael Simonson, and Christian Tanguy. In contrast, over half an hour separated the women's first and second place contenders, Alice Pennington and Danielle Musto.

The 2012 edition of Lumberjack 100 was a sold out event held under unusually hot, dry, and sandy conditions. Barry Wicks and Amanda Carey won the Men's and Women's Open divisions.

In 2011, a full field contended, ending with the winners finishing in record times; Women's Open winner, Amanda Carey; Men's Open winner, Christian Tanguy.

The 2010 Founders Lumberjack 100 is in the books. No crazy storms or heat to write about this year. The week leading up to the race included a few thunderstorms and that made for some great soil conditions this year. In this edition of the race, the course was changed from four 25 mile laps to three 33 mile laps, creating a number of challenges with 2 way traffic. Compared to previous years, a larger percentage of participants completed the event. Many racers commented that the 3 lap race was mentally easier, but physically harder due to the use of some killer single track climbs never used in the race before.
