The No-See-Um Family Fun Ride (3.5 miles)

The No-See-Um is a short, family-friendly ride that’s great for kids, first-timers, and anyone who wants the InSayner experience without the “why are my legs negotiating with me?” moment.

It’s still the InSayner, though—so expect a dash of adventure:

  • Cross Plum Creek on a bridge on the way out
  • Cross Plum Creek again on the way back… this time without the bridge
    No worries: we’ll have volunteers at the crossing to help anyone who wants it.

If you’re racing the InSayner and ask for help at the crossing, we can assist too… for an additional $50.
Just kidding. Racers don’t get help. You did sign up for the InSayner.

The Swarm Adventure Race (15 miles) — Highly Recommended

A backwoods biking adventure that mixes variety, flow, and “wait—this is still going?” in the best possible way.

Expect a little bit of everything:

  • Snowmobile trail sections
  • Fun downhill stretches
  • Logging roads, gravel, and a short bit of blacktop
  • A few surprises designed to make average riders question their life choices

But not you. You’re here on purpose.

The InSayner Back Country Race (25 miles)

The signature event: challenging, fast, and wildly fun—a course that rewards steady effort, smart pacing, and riders who can grin through the occasional gut-check.

The route starts in Sayner at the Community Center, heads out on snowmobile trails to the single track at Musky Mountain bike trails, and then winds through a true Northwoods mix of trail and backroad terrain, including stretches near Plum Vitae Road, Klondike road and Ross Lake Road, before bringing you home on snowmobile trails.

A few friendly notes from your race directors:

  • This is tough—but it’s doable if you pace yourself and keep the wheels turning.
  • There’s a cutoff: make it in time and you stay on course; miss it and you’ll take the alternate route back.
  • No dramatics required. Hydrate, fuel, and keep moving—future you will be grateful.

Come for the challenge. Stay for the community. Leave knowing your ride directly supports LAMBO trails in Northern Wisconsin.

See you inSayner!
Yours truly,
Danny and Mike O.

About This Sport

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

Mountain biking takes place on singletrack and natural terrain where reading the trail matters as much as fitness — cornering, braking, and instinct on dirt are skills that only come from time in the saddle.

Events range from beginner-friendly cross-country races to technical enduros, and the trail community is one of the most welcoming in endurance sport.

Mountain Bike

XC races, enduros, and fat bike events across U.S. trails. Technical, physical, and completely different from anything on pavement.
