These suggestions assume that you’re able to train four time per week, but at the same time attempt to vary (or periodisize) the sessions from week to week. To vary the volume is not very relevant, since the number of total hours is relatively low every week. I also assume that most of you can ski close to home, or have access to ski-trails relatively nearby. In case you do not have snow, the interval training and eventually the short distance session should be done spinning or on foot. Try then go get two ski sessions done during the weekends.
With a four-session training week I suggest the following:
1. A long, (very) easy distance session of 2 – 3 hours
2. A short distance session with a little higher intensity or speed. Easy terrain with lots of double-poling. Put in a few speed or changes in cadence, for example 6 x 10 seconds with long recovery in between.
3. Warm-up and strength (Running or spinning as warn-up)
4. Intervals in form of long intervals (3 – 6 minutes), natural intervals or systematic intervals (1-2-3-4-4-3-2-1 or similar). Long intervals are best and most efficient if trying to improve your aerobic capacity. Shorter (and faster) intervals are best closer to your main marathon competition.
5. Competition. If you’re racing on one of the weekend days, you may perhaps skip the interval session, or use the race as the fifth training session.
Here’s an example of a three-week training plan with four or five sessions:
1. Easy distance 2+ hours
2. Natural interval: 20 min warm-up, 30 minutes natural intervals. Use a variation of terrain, and let the terrain determine the intensity and heart rate. Don’t get lactic, but you should feel that you’re going hard.
3. Run/Spinning and strength
4. Short distance in easy terrain, extra double poling – 1 hour
5. If you race, cut out session number 4 if you feel you’re getting tired.
Example of week with three sessions:
1. Easy distance 3 hours
2. Intervals, hard 2-3-5-3-2 minutes with 2-3 minute recovery in between. Take enough recover such that you are ready to go pretty hard on each burst. Hilly terrain.
3. Short distance (1 hour) in easy terrain, mostly double poling + strength for stomach and back
Example of week with four sessions:
1. Easy distance 2:30+ hours
2. Intervals, controlled 4 x 6 minutes in varied terrain, recovery about 3 minutes in between
3. Short distance including some speed (double-pole) – 1+ hour
4. Running/Spinning and Strength
