About This Race
The 50K option provides a traditional ultra distance on the Arctic Frog course, balancing accessibility with genuine ultramarathon demands. The 417 feet of elevation gain creates rolling terrain that tests endurance without overwhelming newer ultra runners. December conditions become a primary factor, making this distance ideal for runners stepping into winter ultras or experienced ultrarunners seeking a less technical winter option.
The Arctic Frog Run utilizes a loop-based course that's approximately 70% asphalt and 30% crushed limestone trail. All distances share the same basic loop structure, with the 15K covering 2 loops of 4.65 miles each, while the longer distances use 6 or 10 loops of a 5.17-mile circuit. The course offers scenic panoramic views of Mayville and features rolling terrain with moderate elevation gains.
The mixed surface provides variety underfoot, transitioning between paved sections and crushed limestone trail segments. The loop format allows runners and crews to plan strategically, with multiple opportunities for support and pacing adjustments. An interactive course map is available through the race website, showing the yellow-marked route direction.

Notable Features
The Arctic Frog Run's defining characteristic is its December timing, which often transforms the southeastern Wisconsin landscape into what organizers call a 'winter wonderland.' The loop-based format creates a supportive environment for runners attempting their first ultra, while the mixed terrain of asphalt and crushed limestone provides enough variety to keep longer distances engaging. The race's eleven-year history demonstrates its reliability as a winter running option.
