Best Terrain for Skimo Intensity Interval Training: Groomed Ski Runs or Skin Tracks?

In any competitive sport, once you want to improve your speed beyond a certain plateau, you’ll have to incorporate regular high intensity sessions – Zone 3 to Zone 5 – into your training.

Skimo is no different and its various technical aspects introduce even more complexity compared to running or cycling. Skimo race courses travel across a variety of terrain, with most including more technical climbing than just going straight up groomed runs.

With that, you might be wondering whether you should do your intensity interval workouts on nicely groomed runs or in a skin track?

Regularly including various technical aspects of skimo racing in your workouts is crucial to your improvement.

Comparing Terrain: Groomed Ski Runs vs Skin Tracks

Comparing the two by looking strictly at the terrain, the difference is obvious. Groomed ski runs are easy to climb up even for a skimo novice while skinning in a skin track requires more skill, especially, if your are trying to go fast.

Here are a couple of less obvious points how skinning between the two “terrain types” differs:

  • It’s easy to set into a steady rhythm for long periods of time on a groomed run. Skin tracks with switchbacks break your rhythm often – whether that be your breathing or stride.
  • Having consistent skin traction on a groomed run is much easier than in a skin track because keeping good balance is less challenging.
  • Skin tracks usually have switchbacks, thus, your proficiency in kick-turns is crucial to maintaining your speed throughout the climb or high intensity interval.

We can point out even more differences but the bottom line is that skin tracks require you to be a much more proficient and technically skilled athlete than groomed ski runs.

Intensity Interval Training: Which terrain should I use?

Now that we are clear on the difference of the terrain types, let’s take a look at how you should decide what workouts to do on groomed ski runs and which ones in skin tracks with kick-turns.

Consider Your Goals and Upcoming Races

The two most important factors that should drive your decision making when “designing” your intensity workout will be:

  • The goals you have for that workout as part of your overall training goals.
  • What type of terrain you expect to encounter in upcoming goal races?

It should be clear that if you are training for vertical races primarily then performing intervals in skin tracks is not critical to your improvement. In fact, in this case, it might be even be detrimental.

The opposite is true if you are training for a classic European skimo race like the Pierra Menta which courses take place almost exclusively in skin tracks and the race includes many technical aspects overall.

Interval Workouts Suitable for Groomed Ski Runs

Early season interval workouts, at least the first few, are best done utilizing less technical terrain, otherwise, you might simply not be able to hold the required intensity for long enough (which is crucial for further progress).

VO2max or Zone 4 high intensity intervals (5x 5min) are also more suited to be performed on ski runs because holding the high intensity for the entire length of the interval is important in developing your VO2max.

Another example would be maximum speed sprint-style intervals (30x 30sec full-out efforts), it would be counter productive to perform them in a skin track. After all, the goal with these is to generate as much power as possible so it’s best when the snow surface is very supportive and consistent.

Interval Workouts Suitable for Skin Tracks

As already discussed above, depending on your goals and upcoming races, there are times when you can enhance your improvement by performing certain interval intensity sessions inside skin tracks with kick-turns.

If your goal race is a couple of weeks away and you know it will have plenty of skin track skinning, then completing your long intervals (3x 10min) and your high intensity intervals (5x 5min or similar) using the same terrain as the race course will make you feel super strong and confident when the race day comes.

Once you achieve a certain level of technical proficiency, occasionally moving your interval workouts into technical terrain will continue to enhance your skimo progress. As long as you are able to hold the prescribed intensity, in any terrain, you will greatly benefit by matching the race environment as close as possible.

Early Season vs Race Season

Early in the season, the priority of your interval workouts should be on building your engine. Work on technique during your long, easy Zone 1 sessions. Create the best possible conditions (including terrain choice) for a given workout to gain the maximum benefits for the time you spend. Just like you wouldn’t do Zone 4 intervals using your powder ski gear, you wouldn’t want to choose terrain that prevents you from keeping the required intensity or speed.

As your season progresses and your goal races are approaching, design your workouts around the demands of those races. Unless you want to be a pure vertical race specialist, you will need to develop your technical skills while you are breathing heavily and your balance is compromised. Besides, the technical aspects are what makes skimo so appealing and interesting.

Sprint Race Training

Skimo sprints are a special kind of races that require great technique at high speed in quickly changing terrain.

They seem simple at the first glance because they are so short, however, even without considering the many transitions, a sprint race is arguably the most challenging event to pull off successfully on consistent basis.

With that, performing high intensity intervals on sprint-like courses is one of the best ways to improve your skimo skills quickly because anything done well at high speed will be much easier to repeat when your heart rate is lower.

Personally, I have never liked short events (because I was never very fast out of the gate) but I have incorporated various aspects of sprint races into my training as I saw it as a very efficient use of time.
