The Ravens is an award earned by one male and one female who win the best overall times in all three of LAMBO's races.

Fatathlon Fat Bike and Corn Hole Biathlon Fat Bike Race The Fatathlon is a fatbike biathlon race at the Shannon Lake Trail in St.Germain, WI. But don't worry, no firearms are used in this biathlon. Instead, riders must demonstrate their skill at the cornhole/bags toss. Make sure to brush up on your skills because the toss can win you the race!

Rip, Zip and Sip Fatbike Race The Rip, Zip and Sip is another fatbike race with a couple of twists. In addition to one of the best fat bike race routes in Wisconsin, riders must jump slide down the finish hill and cross the finish line, on a sled! Additionally, riders get a free zip line ride as part of their registration.
The InSayner adventure mountain bike race.And finally, the InSayner. Held in Sayner, WI (see what we did there?) this mountain biking race is a challenge in of itself. The race course winds it's way through the forests and streams surrounding Sayner and Musky Mountain. But another reason it's called the InSayner is because this course is hard. There are some brutal climbs, river crossings, and bugs. There will be bugs!
