Training Programs: Choose Your Volume
Same structure, different volume. All programs follow polarized training with two hard sessions per week — the difference is how much zone 2 volume you build around them.
One framework, five volume tiers
All our training programs are built on the same philosophy: two hard sessions per week (one VO2max, one threshold), the rest zone 2 volume, and a 3:1 mesocycle to manage load and recovery. The only difference between programs is how much time you have — the structure is identical.
As you go from 5 to 20 hours, it's the zone 2 volume that grows. Not the number of hard sessions. Not the intensity. Extra time means longer easy sessions, longer long rides, and more zone 2 days — never more intervals. This is the fundamental principle of polarized training.
Shared principles across all programs
- 2 hard sessions per week: 1× VO2max + 1× threshold
- All extra time goes to zone 2 — never to more intervals
- 3:1 mesocycle: 3 weeks building, 1 week recovery
- At least 1 rest day and 1 recovery day per week
Choose your training volume
Choose the program that matches the time you actually have available — week after week. A program you complete consistently is better than an ambitious program you complete half the time.
Time-constrained athlete
When time is short, prioritize intensity. Two hard sessions and two short zone 2 sessions deliver surprising returns.
Volume starts to count
Eight hours provides room for a long ride, strength training, and three to four zone 2 sessions alongside the two hard ones.
Solid aerobic base
Ten hours builds a clear aerobic foundation with a proper long ride and a dedicated recovery day.
Serious aerobic volume
Fifteen hours delivers long zone 2 sessions, possible double days, and a long ride that truly builds capacity.
Dedicated athlete
Twenty hours requires mandatory double days and massive aerobic volume. Still only two hard sessions — the rest is zone 2.
What changes with volume?
The structure is identical. What scales is session length, number of zone 2 days, and long ride duration. Hard sessions stay at two per week regardless — that's what gives polarized training its power.
Here's an overview of what actually changes from 5 to 20 hours:
| Volume | Hard sessions | Zone 2 sessions | Long ride | Special |
|---|---|---|---|---|
| 5 h/week | 2 × 60 min | 2 sessions | 90 min | Prioritize intensity |
| 8 h/week | 2 × 75 min | 3–4 sessions | 2–2.5 h | + strength training |
| 10 h/week | 2 × 80 min | 4–5 sessions | 2.5–3.5 h | + recovery day |
| 15 h/week | 2 × 90 min | 5–6 sessions | 3.5–5 h | + double days, indoor/outdoor |
| 20 h/week | 2 × 90–100 min | 6–7 sessions | 4–6 h | Mandatory double days |
Notice: the number of hard sessions is always two. That's the most robust training rule we know — two different high-intensity sessions per week produce broader adaptation than one long or three half-hearted ones.
How to choose the right volume?
Choose based on the time you actually have — not the time you wish you had. A program completed consistently for eight weeks beats an ambitious program that falls apart after three.
Rules of thumb for choosing volume
- Choose the volume you can complete 9 out of 10 weeks without stress
- Counting commuting and everyday activity? That's a bonus, not part of the program
- Better to start low and increase — it's easier to add a zone 2 session than to remove one
- Life changes: move between programs based on season, work, and life situation
You don't have to choose one program for all time. Many athletes alternate between volume levels throughout the year — lower during busy periods, higher when life allows it. The structure and principles are the same regardless.
