What Vande Velde means is that different intervals train different physiologic capacities. The one minute, or “kilo,” helps build short-term, explosive power. This type of fitness will help you close or bridge a gap or escape in the final kilometres of a race.
The “endurance”-type intervals works at a slightly lower intensity and builds longer-term muscular endurance for sustained climbs, windy road races or time trials. The advantage of doing pyramids is that you’ll train over a variety of zones during your workout.
The pyramid can be done on a road bike, indoors on a trainer or rollers, or out on the road. Vande Velde further recommends doing your intervals on the same terrain (a long hill, stretch of road, or wherever) each week so you can gauge your fitness as you improve.
After you’ve reached a solid base of general training, it’s time for your pyramids. One day a week, one day on the weekend, maximum. Intervals are like a powerful drug: Just a little and you’re flying high, too much and it’s lights out.
Start with one pyramid (one set of a one-minute, two-minute and three-minute effort with a minute’s rest after each) during your workout, and after a few weeks add a second pyramid set. Take every fourth week off to avoid overtraining.
Eg: – All efforts at High Zone 3 (85-90% effort) – Warm-up: 10-15 Minutes – 1 minute effort – 1 minute recovery – 2 minute effort – 1 minute recovery – 3 minute effort – 1 minute recovery – 2 minute effort – 1 minute recovery – 1 minute effort – 1 minute recovery – Warm-down: 10-15 minutes
Suppose you’ve got a bit more time to put into your workouts. Cycling is one sport into which you may pour endless hours and energy, so if you’ve got the time and motivation, we can go nuts here.
We can get a little more specific on the bike, for starters, and that’ll take up time and energy, believe me.
Another productive type of interval is the “cruise” interval. The cruise interval involves a longer interval, done at a slightly lower intensity. As with all intervals, you want to ride strongly throughout the length of the effort. Don’t start hard during a 15-minute effort, only to crater and crawl the last five minutes. Get yourself up to an intensity you can hold for the full interval and keep it there.
A cruise interval will build longer-term endurance at an exertion level just below your anaerobic threshold. This will give you stamina for longer climbs, a time trial and the sustained effort of a bike race.
Warm up, do a 10- or 15-minute effort, then recover by spinning an easy gear for five minutes or more (at least until your heart rate is down in zone 1 again, in which you’ll be able to breathe through the nose comfortably). If you’re up to it, try another, but remember that you want to finish the interval as strongly as you started it.
As with all intervals, you’ll want to only do them as long as your body’s responding. As soon as you can no longer raise your heart rate to the targeted level (high zone 3 for a short interval, high zone 2 or low 3 for a cruise interval — roughly, gauge your own intensity), it’s time to warm down and go home.
Likewise if your heart rate doesn’t return to recovery level (zone 1) then it’s time for the showers.
HOW AND WHEN?
You want to focus on consistency, good form and steady effort. This way you’ll get a more thorough workout, rather than stopping to put a foot down or changing your cadence dramatically.
And remember Vande Velde’s advice on where to train. Try and get back to the same hill or road for your intervals and pretty soon you’ll notice you’re covering more distance in less time … and that means your fitness is coming along nicely.
