666 Spots. Register

2022 Registration

It’s going to open at 8:00pm sharp. No trickery. No early opens. Just a good ole’ fashioned mass panic attack to get registered before it sells out. This is not a joke! Everyone is gonna have one shot to get in, all at once. Don’t take Friday off, or waste your time checking mid-day. 10.15.2021 at 8:00pm. It’s go time.

You’ve been warned!

Where is registration hosted?





Why did the price go up?

We’re a non-profit helping other communities develop Adventure Teams. Trail donations. Rising costs. We’ve held off for three years and had to make a move. We hope you understand.

Registration News & Notes

No waitlists.

Marji Camp registration includes an entry to the race. 

Transfers end 8.01.2022.

You cannot transfer an entry from bikereg.com to ultrasignup.com, or vice versa.


The women’s field has gone from 10% to 20% since 2018. In 2021 250 women were registered, but I digress for a moment…

Since 2018 we’ve registered around 1,100 people each year. We have no plans to grow beyond this level. The experience of Marji Gesick is more important than the revenue.

The uncapped field for women has been effective, and brought some challenges with it. Most notably, people taking advantage of the uncapped field. We monitor it as best we can but the truth is we don’t have time to make sure folks don’t abuse the system.

On October 15th, 2021 we’re opening registration with 666 spots available for bikers between the MG100, MG50, Mini-Marji, and the Duathlon. The entries will be unrestricted, meaning you if you get one you can feel free to use it or transfer it to whomever your little heart desires.

At 8:01:30, when registration is full, I want to see our field split 75/25. Lets make it happen.



There’s a new buckle in town… and anyone can have it. After they’ve ridden 1,000-miles of Marji Gesick. You’ll get retroactive credit for all miles ridden back to 2015, as long as you #finished. All of the events qualify, including Mini-Marji. Oddly enough, if you do nothing but the Mini it will take 66.6 years to claim the buckle. Can’t make this stuff up! To celebrate this sick new idea we’re offering double-miles in 2022, but the first challenge will be getting a spot!


The Mini is moving… to Negaunee. We’re still working out a few logistics, but we can share in 2022 the Mini-Marji will cover the infamous “Last 15-miles” and have a proper finish line in downtown Ishpeming with everyone else. 



How do you prepare to finish “The Marji”?

Two words: MARJI CAMP.

Spend 4 days with us on course, learning the key tactics you’ll need to survive, and complete the Marji Gesick.


The Triple Crown consists of three of the toughest events on bike or foot. From the grueling singletrack of Marji Gesick, the relentless wilderness of The Crusher, or the unpredictable weather of The Polar Roll, 906 Adventure Team events are no walk in the park. Athletes that complete one from each of these three events below are granted lifetime entry into our Hall of Pain and are eligible to attend our annual “secret event.”

You do not have to complete all three challenges in the same year, you just have to complete one of each sometime in your lifetime.


12-hours (100-mile bike)
22-hours (Duathlon)
28-hours (100-mile run)

The 100-mile bike and the duathlon event both begin with a .5 mile run.

What is a LeBike?2019-06-10T18:17:37+00:00

It’s the opposite of a LeMans start where riders run to their bikes. In this case, you bike 0.5 miles to your run. Bring your own bike and helmet.

Have a plan. Be prepared. Bring the right gear. Bring enough food.

I heard there’s actually a lot of aid from the locals. True?2019-04-24T20:11:56+00:00

The race does not operate aid stations or provide support. What someone else does or does not do is out of our control. If you show up expecting help from someone you are making a grave mistake.

Blame Todd or Blame Danny.

Why is GPS mandatory?2019-04-24T20:12:47+00:00

GPS is mandatory because no one can control what is going to happen to the signs we put up. With GPS, regardless of what the weather does to the course or other variables outside our control, you can still navigate and finish the race.

What is the “Self-Supported Ethos”?2019-04-24T21:08:44+00:00

In 2019 I followed my own training plan to prepare for the 100. Having just completed the P2P Crusher a few months earlier, I felt fairly confident. [SO naive]
I missed the Jackson Park cut off by 38 min. I learned a lot from that experience and it fueled the fire of unfinished business.
Step one for 2020: purchase a Marji plan
I started the general “Finisher” Marji plan, then Covid happened. Completed the Polar Roll and went on to Fist that summer. I used parts of Rob’s plan to help me prepare for these events.
The opportunity for Project Adventrus presented itself.
AFI: prepare yourself in every way possible to complete the goal
Step one for PA: hire a coach
I knew Rob was training Todd for PA, so it was an obvious choice.
I met with Rob via Zoom and learned so much about endurance training in one visit. I immediately felt confident in his ability to prepare my body to bike around the UP on gravel, sand, road, etc.
PA was a success. I felt back to my normal self in 3 days.
Rob knew Marji was my “A” race all along. He recovered me after PA and I felt ready to begin Marji training 2 weeks after finishing PA. Biking and training started to lose its luster after a while. Rob offered to help me from a sports psychology standpoint, though I was able to get myself out of the funk and continue on plan. He knew, all along, my goal was to finish Marji and he prepared my body to do just that. I finished in 23:50. This time, by no means reflects Rob’s coaching. My body could have done it faster. My mind kept my body and bike safe, choosing not to ride technical downhills in the dark. I felt back to my normal self in 1.5 days.
Rob is an incredible coach. He provides feedback each week, adjusts your plan if needed (for both body response and life events), responds to emails quickly, is open to providing sports psychology support, and educates you along the way. You put in the work and he will bring you to your green dot. I look forward to working with him again! – Kelsy Kellerman

Pro tip: don’t buy a plan before you have a race entry confirmed, Rob is not able to offer refunds. TrainingPeaks is own their marketplace, he is allowed to use it as an accredited coach, but they handle all the billing. Their refund policy is HERE should anyone wish to read it.

It’s all about community.

906 Adventure Team is a 501c3 Non-Profit based in Marquette, Michigan. Since 2014 we have been creating outdoor adventure experiences for youth through Adventure Bike Club and events like Polar Roll, The Crusher, and Marji Gesick. Our take on life is pretty simple – it’s an adventure. In life (and adventure) stuff doesn’t always go to plan. Things go wrong. Bad things happen to good people and you don’t overcome it by complaining or pointing fingers. The truth is adversity brings out the best of us – by taking us down unknown paths to find it. 


906 Adventure Team uses revenue from the events to support trail organizations and create more youth Adventure Teams. 


The Marji Gesick will donate $27,000 to local trails this year, bringing total trail donations since 2015 to $216,000. 


In 2022, with the help of corporate partners, we invested $40,000 in youth programs for three new Adventure Team communities. Resilience, confidence, community, and a sense of belonging have never been more important than it is for kids today. Adventure Teams help them “find their people”, the way you feel like you’ve found yours at Marji. 


We want you to know when you support 906 Adventure Team and the events you’re making life better here in Marquette County and in communities across the Midwest.
