Not to be confused with The Raven Trail, 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.

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!

The Rip, Zip and Sip is another fatbike race with a couple of twists. In addition to one of the best fatbike 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. 

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!

The winners are awarded at the InSayner race.
