The 6633 route takes you through some of the most stunningterritory on this planet..

Most of the race is based either on the Dempster Highway or on ice road.
Depending on the edition and distance you can experience stunning hills or
hypnotic flat ice. Every distance comes with its own challenges.

Anyone who decides to take part must understand that the race is an
adventure, an expedition, it is subject to the environment which means there
isn't one plan and there isn't just one route for the crew or the athletes! Be
prepared to adapt!!

The 6633 is run primarily to feed the adventure need of the crew and the athletes. We do everything we can to make sure all our participants get the adventure and race they are looking for, whether it is the 120, 250 or 380 mile distances. We want as many people to finish as possible - but be prepared, not that many do. Just getting to the start line is an achievement in its own right.

This is a self sufficient experience, that means you move, sleep and eat when you want to, its your race. We provide safety checkpoints with access to hot water and temporary respite from the environment. You sleep in the wilderness, camping along the route where you choose. You cannot sleep in the checkpoint vehicles or trailers, however, where a building is used for a checkpoint (e.g. school hall) you may use these spaces to sleep in.

Each race has a required completion time. Whilst there are no hard cut offs at the checkpoints, if you haven't got enough time to complete the distance then your race will be over. It is important to stay on top of your progress and know how far and how quick you need to move.

Depart Whitehorse: 22/02/28

Classic Race Only: CAN’T DECIDE…. We are often asked if it is possible to enter the 120 mile race, but then have the option to have a crack at the 380 mile event if everything is going well by the time you get to Fort McPherson. In earlier races, to the greatest degree we tried to accommodate these requests. However, to leave this open ended didn’t seem very fair on those who enter the 380 mile event outright. So since 2011 in order to address these matters we have introduced a 120 mile +. The athlete who takes up this option will initially be listed and compete in the 120 mile event and will have a result in that event should he/she decide to finish at Fort McPherson. If an athlete in the 120 mile + category then decides to continue in the 380 mile event, their result in the 120 mile event will become void the moment they leave Fort McPherson and they will continue as a competitor in the 380 mile event. It sounds complicated but hopefully not too much so as it seems a fairer way of allowing athletes to participate who simply can’t make up their minds.

Eagle plains 1 night stop over: 23/02/28

We will provide within the entry fee the Hotel accommodation in Eagle Plains prior to the event and similarly for those returning from Tuktoyaktuk at Eagle Plains on the way back to Whitehorse. This accommodation will be on a shared room basis (2 or 3 person). However, if a single room is required at Eagle Plains, this can be arranged, albeit the additional charge of such a room will need to be borne by the athlete and will be payable to the organiser in Whitehorse prior to departure. Whilst the exact figure is not currently known, its likely to be in the region of an additional $80cdn per night and the availability of such rooms will likely be limited – so please advise as soon as possible if you would like us to arrange this upgrade for you.

Race Start : 24/02/2028

A cash deposit of $200cdn will be collected off each competitor during the Pre Race Kit Check-in that will take place in Whitehorse prior to travelling north to the start. This deposit is to cover the possible additional accommodation costs at Eagle Plains should the race start be delayed due to circumstances beyond the control of the organiser and/or to cover the same such costs should the return journey at the end of the event be hindered due to road closure. Subject to there being no delays in either direction, the deposit money will be returned to each athlete at the conclusion of their respective race. To date this deposit has never been called upon.

Finish date: 04/03/28

From the time of booking until September 30th all cancelled bookings will be subject to a £600 cancellation charge. From October 1st to 31st December all cancelled bookings will be subject to a £1,200 cancellation charge. Any cancellations during January will be subject to a £2,000 cancellation charge. After the 1st February cancelled bookings or non attendance at the race will result in a 100% of the entry fee cancellation charge.
