Off Season Base Building for the SkiMo Season


Winter sport athletes face a unique problem when it comes to training for their sports. Cross Country ski racers train 7 to 8 months of the year NOT doing their sport in preparation for a 4 to 5 month racing season. They’ve had to become very clever about sport mimicry and fooling their muscular and nervous systems into believing that they are doing something very close to skiing. They call this “dryland training”. SkiMo can benefit by looking at some of the things their XC brethren do in the off season.

Off Season Training for SkiMo

If you are waiting until November or December to start training for your Skimo season but wondering where you might find an extra edge in the next season’s races, then you need to look no farther than your dryland season. A good 90% of your performance results during the race season can be attributed to the work you did in those long months without snow. If you are not taking advantage of this off-season then you have no one to blame for your lack of results but yourself.

That new, ultra light weight (and ultra expensive) set up WILL help you…drop your times by 1-2%. For sure there are those elite few for whom that extra margin will be decisive in victory. But, for most of the field, proper off season training can net you gains well into the double digits.

Off-season is the time for building your base, meaning improving you ability to handle ever increasing training loads. First and foremost this should focus on your aerobic system, but strength and technical proficiency should not be ignored.

Technical skill development

Some Skimo racers today are coming into the sport without a strong ski background; either XC ski racing or downhill skiing. These new skiers lack the ski-feel of an experienced skier. Skinning uphill is a lot more than just putting one foot in front of the other quicker than the next guy. The race courses may be roughly evenly divided between up and downhill with a small portion of flats but the time spent on the up hills, to say nothing of the energy expenditure required to climb them, makes the uphill portions of the event the place where you stand to gain or lose the most time.

Most racers falsely attribute their relative success or failure to their fitness alone. We all recognize (and feel) the direct role fitness plays on the up hills as the energy cost of the work though our breathing rate and depth as well as our muscular fatigue. The energy usage required to maintain a given speed is known in exercise as economy and is analogous to the fuel economy of your car. Reducing that energy cost through improved economy is a major factor in how elite endurance athletes maintain faster paces for longer than the rest of us.

We believe strongly that in your off season base building period you would be wise to spend at least 30% of your training time in ski specific simulation exercises to improve your economy at the same time you are working on fitness. The following sections give some tips on how this work can be done. Our Skimo training plans, available here, include these sport specific workouts.

Cycling Won’t Cut It: The importance of weight bearing training for Skimo

If you hope to achieve your best Skimo results you need to be training with full weight bearing exercise. While we understand the appeal of cycling, and for some injured athletes it is the only alternative, it cannot compare to the overall training loading of running and the other methods we recommend below. Even in walking the forces through each foot/leg/hip musculoskeletal structure is about 1.5 times body weight. When running, even at moderate paces, these forces increase to 2-4 times body weight.

Every foot strike for a 150lb runner is loading each leg with 300lbs of force. Typical trail running cadence is around 150 strides per minute so in a 1 hour run your musculoskeletal system must absorb 300lb loads 9,000 times. Compare that to the average pedal force to sustain 16 miles/hour on flat pavement (about 200 Watts power output) on a 1 hour bike ride.

The average maximal pedal force for our 150 lb rider is 93 lbs. At a pedaling cadence of 90 rpm you would be applying 93 lbs to each leg 10,800 times. It should be pretty self evident these training loads are vastly different. This does not take into account the postural work needed to hold the body erect during weight bearing exercise or the single leg balance and coordination need to transit long sections of rough terrain on foot.

The trail running example suggests a cumulative training load of 2,700,000 pounds while the cycling example suggests a load of only   1,004,400 pounds. Thus, trail running places 2.7 times more training stress on your body for the same training duration. Over the course of a training season, that increased load and specificity should have a huge impact on your performance.

The training effects of all foot borne exercise transfers well to other foot borne exercise. The same cannot be said of cycling’s transfer of training effect. In fact Scott Johnston used to have a Norwegian XC ski coach with decades of coaching experience who would only allow him to count our bike training time as 1/3 of its actual duration; so a 3 hour ride was equal to a one hour run.

Skimo Specific Exercises

In addition to choosing weight-bearing training modes whenever possible, there are a few sport-specific training exercises that Skimo racers would be wise to borrow from Nordic skiers.

Ski Striding

Because XC ski races take place on hilly terrain, like very scaled down Skimo races, XC skiers spend a big chunk of their time training on hills with poles. While running should be your go to training modality for most days you can gain significant specific fitness by training on hilly trails with ski poles and simulating a ski striding motion. This movement accentuates the longer stride of skiing compared to running. It targets the ski specific leg muscles which are the glutes and hamstrings along the back of the leg rather than the quads which get the most work in running up hill.

It is not as economical as running up hill and so the training will feel somewhat contrived. You could move faster with less effort on all but the steepest hills by running. But the transfer of training effect is much better than running for a skier. Striding will allow you to keep your heart rate in the aerobic zones so it is great for a long distance outing in the mountains. You’ll end up using a mix of striding the ups, and running the flats and down hills. 

Check out our video tutorial on how to implement this training.

Ski Bounding

A variation of striding, bounding has all its benefits but is meant for higher intensity work. Commonly for interval workouts on moderate to very steep hills. It uses an exaggerated bounding movement that is not as economical as running but places very high load on the leg ski muscle. We use poles for this training just as for striding.

Roller Skiing

This is the training that separates the casual Skimo racer from those seeking to make serious gains. Roller skis are short ski-like devices with small rubber wheels designed for XC ski training on pavement. XC skiers use both skate and classic skis but for Skimo you’ll want to get yourself a pair of classic roller skis. The rear wheel of the classic skis has a one way bearing so that wheel will only roll forward and lock up when you kick off the ski just like you skins do.

Training on hills on roller skis allows you to very closely mimic the on snow techniques of skiing up hill. The fitness gains transfer directly to Skimo just as they do to XC skiing but equally important is the balance, subtle weight shift, and glide that it teaches. This practice will do amazing things for your skiing economy. We have had several Skimo racers tell us after they began to train on roller skis that could not believe what terrible technique they had been using on snow.
