Race Rules

Please be advised:

Any racer who fails to comply with the following rules will be disqualified from the Tanana River Challenge. Absolutely no refunds will be given to a racer who is disqualified.

If you are under 18 you may participate with the Race Directors discretion. Please contact before registering.

Race Day Check-in and Bib Pickup:

All racers must physically sign-in at the start line.

For 45 mile racers this is between 7:15- 7:50 am.

For 25 mile races this is between 9:15 – 9:50 am.

Any racer who fails to sign-in at this time will forfeit their entry.

Any racer who is registered for the 25 mile course can bump up to the 45 mile course at check-in but they will be required to pay the difference for the longer course.

A division (bike, ski, skijorer, run) must be confirmed when each racer signs-in.

We will have a short meeting 1/2 hour before each start for all racers.

Human Inclusive Race:

No motorized equipment may be used to facilitate a racer in any way.


No loose dogs. Skijorers must be in control of their dogs at all times. Please only bring dogs that will be friendly to fellow dogs, skijorers, skiers, bikers and race staff. Any dog that has been flagged at other events for inappropriate behavior is not welcome at this race.

No Outside Help:

Racers must be self sufficient and are only allowed to accept help from another racer or race official.

Racers are not allowed to accept any help from a race official or fellow racer that advances that racer along the course.

Race Gear:

Racers must finish with the same mode of transport equipment that he or she started with.

Racers may not purposely leave any gear, clothing or equipment on the trail or at a checkpoint.

The TRC will not provide dog drop services to skijorers. The skijorer can either ferry the dog out via pulk, or chose to evacuate themselves and their team.

Please keep in mind that vehicular access to the Tanana River via the Rosie Creek trail is prohibited as it is a private driveway. **

Stay on the Marked Course:

We mark the course VERY well. There are mileage signs and we let you know when you’re approaching a checkpoint. Any turns have signs and flags. Anyone going off course and not returning to the same place to continue will be disqualified.


All racers must physically check-in at all official checkpoints.

Racers must show their race bib to the checkpoint volunteer, who will then sign in that person and record a check-in time.

Any racer who misses or skips an official checkpoint will be disqualified.

Race equipment is absolutely not allowed inside the tents at the checkpoints; this includes bikes, skis, poles, dogs, and sleds.

Cut-Off Times:

The finish line shuts down at 7 PM. This leaves 11 hours for the 45 mile course and 9 hours for the 25 mile course.

All racers must adhere to the cutoff times for departure from each checkpoint.

Any racer that is unable to depart a checkpoint by the cutoff time listed in the table below will be evacuated off of the course by snowmachine as permitted by race personnel.

A fee of $100 will be charged to the racer in the event of an evacuation.

Dogs being evacuated will be placed into kennels and towed on a snowmachine sled. The skijorer should inform race personnel of any dogs that are exhibiting/can exhibit aggressive behavior, and should take steps to minimize those risks to themselves and/or race personnel.

Any racer who is unable to complete the race will be disqualified. If a racer is able and willing to return to the start under his or her own power, or with the assistance of an external source, he or she may do so. BUT all racers MUST inform a race official if they intend to scratch and return to the race start.

ALL racers are ultimately the responsibility of the race staff and MUST be accounted for at all times. In order to accomplish this, a disqualified racer may require an evacuation or snowmachine escort back to the road system.


Any racer intentionally depositing litter on the trail will be disqualified.

A Little R-E-S-P-E-C-T:

Be respectful of other racers, race officials, volunteers, and any other trail users along the Tanana River.

Any racer treating others poorly (including dogs), or perceived to be disrespectful will be disqualified.

Do not damage any structures, trail signs, or private property. Treat this area as you would your home.
