Gear Discussion

February offers the most brutal environment an Alaskan winter can summon. Fortunately, near-death experiences in the race are rare, but competitors have and will continue to suffer frostbite and hypothermia, the two principal pre-cursors to tragedy on the course. This fact alone justifies the continuing requirement to carry mandatory gear.

After several years of vague interpretations of the gear rules, the Board of Directors approved the following clarification:

All racers are now required to start and finish the race with at least 15 pounds of gear. The 15 pounds must include the mandatory gear, but may not include the following: water, skis or ski equipment, bicycles, or sleds.

No element of the race has been more controversial than the mandatory gear rule and its enforcement (or perceived lack thereof). As every endurance athlete understands, the minimization of weight and volume are crucial strategies in competition. Hence the temptation to cheat on the mandatory gear.

Although we use pre-race, random in-race, and some post-race gear checks to keep the playing field level, The Susitna 100 relies largely on the honor system. No Susitna 100 winner has ever been invited to the White House or signed a million-dollar endorsement contract. For the most part, we show up, race, have a party to celebrate, and get back to life. As Abe Lincoln said, the world will little remember what was done here. Put simply: please don't cheat.

Required Gear Specifics:

Sleeping Bag

The Susitna 100 requirement for a sleeping bag is:

A one piece sleeping bag (no combination of liners) rated to at least -20 degrees Fahrenheit (20 degrees below 0 degrees Fahrenheit,  =28.8 degrees below 0 degrees Celsius). 

Many sleeping bags now are rated by the  EN 13537 testing standard. 

To use this rating system to meet the Susitna 100 requirement, look at the “lowest limit of comfort”.  Please note, this is NOT the “T extreme”.  Information about the EN 13537 is available on the European Outdoor Group website.  If you have questions about the application of this rating to the Susitna 100 sleeping bag requirement please e-mail  This e-mail address is being protected from spam bots, you need JavaScript enabled to view it  

 There is a good selection of lightweight synthetic bags that will meet this requirement. However, your best bet is to get a down bag, preferably with a goretex shell (in case you actually do have to use the bag). Down fill is still lighter and more compressible than any synthetic fills of comparable insulation rating.

Some racers sleep during this race. If you stop for a few winks, don't expect to find floorspace at a checkpoint. In short, think about your race plan and factor in how you plan to bivouac in the open at 20 or 30 below zero F.

Closed Cell Foam Sleeping Pad 
Your cheapest, lightest, and warmest choice is a closed-cell pad, such as a Ridgerest or blue foam pad. Minimum size is 3/8" x 20" x 48".

Bivy Sack or Tent
A goretex bivy sack is recommended. If you're not into ultra-light hiking and/or climbing you probably don't own one and the $100+ cost may be prohibitive. The one-person tents marketed to bicycle tourists are fine, but will add some ounces to your gear.

Again, you're not likely to use this equipment. But if you do, it's important that your bivy sack be waterproof, especially if your sleeping bag isn't. If you do bivouac, dig or stomp out a trench in a snow bank (not too far off the trail) and use the trench for wind protection and extra insulation.

Insulated Water Containers
The rule requires that you have at least a two-quart (64 ounce) capacity. If you dress properly and avoid sweating, this should be enough to get you between checkpoints. A special note to runners and snowshoers: you will be constantly cycling between hydration and dehydration and you must be disciplined about re-hydrating at checkpoints. It is advisable to carry an extra quart bottle (start with it empty) just in case you figure out that you are not keeping up.

Outdoor Research (OR) makes nice bottle jackets. If it's a cold year (or you are broke), you can make your own out of a sheet of one-inch foam rubber and some duct tape. The plastic bladder (Camelbak, Platypus, or other name brands) is overwhelmingly the weapon of choice. Most competitors are well-informed as to their virtues. Bladders, however, aren't trouble free. Racers must be alert to the tendency of hoses to freeze, especially during the longer periods between checkpoints with which runners and snowshoers must contend.

Try any or all of the following:
* Wrap the drinking tube with adhesive-backed pipe insulation, available at most plumbing and hardware stores;
* Run as much of the tube as possible under your clothes and use body heat to maintain a working temperature;
* Clear the tube after drinking by either blowing back into the tube or raising it while pinching the tip.

In 1993, a racer got second-degree burns on a good portion of his back when his bladder was filled with near-boiling water. He was a mile or two out of the checkpoint, with the bladder buried under layers of clothing, before he realized he was about to become a soft-boiled egg. Think about the outside temperature and the body heat you're generating when you fill those bladders. They can provide a welcome heating pad during a cold stretch or they can turn your clothing into a steam room and sweat you to dehydration.

Bladders can and will leak or siphon their contents everywhere but where the fluid needs to go: into your mouth. Avoid these problems by selecting a dependable valve and then gluing or taping it onto the tube. As with all of your equipment, work with your drinking system, under winter conditions if possible, before the race to find and cure its weak points.

Headlamp or Flashlight
The rule says nothing more than the preceding three words and thus virtually any device you bring to the check-in will be in compliance. Before selecting your light, consider the following rather contradictory factors:

* Winter nights in Alaska do not typically have the same intense darkness you encounter in warm climates where there is rarely any snow. Snow is highly reflective and can achieve great definition with even a small amount of light. However, because some sections offer technical riding on the course, avoid the temptation to cut corners with your lighting system.

* The wilderness through which the Susitna 100 is run is criss-crossed with a number of winter trails. The race course intersects many of these trails, some of which have proven quite alluring. Every year someone gets lost. After 5:30 PM, your headlamp is the best friend you have.

Rear Flashing Light 

For traveling at night or camping, a small red strobe light will alert snowmachines and other people on the trail as to your presence. If you camp for the night, hang the strobe from a nearby tree, a ski pole, or your bike, so roving race officials can take note of your location.

The Rest of Your 15 Pounds

You should have a minimum of five pounds for clothing, additional food, and tools/spare parts to make your 15-pound starting requirement. You must prepare and act as a self-contained unit in this race.

Extra Clothing
You should be prepared for a 40-50 degree temperature swing during the race. In addition, the wind often picks up at night, adding a nice cool tingle to the evening air. Be prepared with lots of neoprene and similar air-tight gear. Think about a change-out of your upper body layers as the sun goes down. You will likely be a bit dehydrated by then and- combined with the cooler ambient temperatures- sweating a bit less. Dry clothes will feel much nicer.

Other Amenities
Much of the course will be within reach of Anchorage's many radio stations. A radio-only walkman weighs but a few ounces, but can lighten your spirits as you trudge down the course. Keep the batteries next to your body, but the antennae wire well-exposed.

It goes without saying in an ultra-distance event to bring a foot repair kit. Since most of us err on the side of caution in selecting foot wear, foot powder should be applied liberally at all extended rests at checkpoints.
