About this training plan
More FTP for intermediate riders: threshold intervals, VO2max and long rides in a clear progression, HR-guided, ending in a 20-minute test. This plan is the next step once you have your first interval blocks behind you.
Who the plan is for
You have trained to a plan before, are familiar with threshold intervals and can ride for two hours or more without fading. Now you want to put more pressure on your FTP, for example ahead of a season of sportives, races or fast group rides. If intervals are still new to you, you are better off starting with Level 1. If you have been training in a structured way for years and with more volume, Level 3 is the right choice.
How the plan works
The core is threshold work on Tuesday and Saturday. On Tuesday the blocks grow from two eight-minute to two 15-minute efforts, on Saturday from three eight-minute to three twelve-minute efforts. Thursday brings a VO2max session with hard intervals of three to four minutes that raise the ceiling of your performance. In the hardest week you tack a threshold block onto this session, so that you learn to ride cleanly at threshold even when pre-fatigued.
In between come easy endurance rides, up to two hours long on Sunday. The first progressive weeks are followed by an easier week that lets the work sink in. In the hardest week, Saturday’s threshold blocks sit within a two-and-a-half-hour ride, preparing you for long, hard days in the saddle. The final week cuts the volume significantly but keeps the intensity. That way you go into the final test fresh. A core stability and stretching session complements your riding in the build weeks.
What you need before you start
- Your threshold heart rate (threshold HR). You determine it with a 30-minute test on the bike before you start – the plan explains how.
- A chest strap. You don’t need a power meter: all targets are given as a percentage of your threshold HR, based on Joe Friel’s proven zones.
- A fan for the indoor intervals, and fuel for up to two and a half hours for the long rides outdoors.
Support within the plan
At the start you get a short introduction to FTP, to determining your threshold HR and to how the plan is structured, plus tips on riding by heart rate on the turbo trainer. Every week begins with a short overview and the test week is explained. You learn how to analyse the test without a power meter and, at the end, how to carry on with your test results.
Which level is right for you?
- Level 1: You are just getting started with structured training. Threshold blocks up to 15 minutes, VO2max intervals up to four minutes, and the long ride stays easy and builds up to two hours.
- Level 2: You already know your way around intervals. Threshold work during the week and at the weekend, more VO2max intervals and, towards the end, threshold blocks within a two-and-a-half-hour ride.
- Level 3: You have trained in a structured way for years and have a solid base. The highest interval density, threshold blocks up to 20 minutes, VO2max intervals up to five minutes, threshold work in long rides of up to three hours and an extra easy recovery ride.
Intensity guidance
Your training thresholds
Session intensity is based on your personal thresholds. After buying, you enter them in the Aspect App – the plan then converts every target for you. If they’re already stored in Intervals.icu, you can import them with one click during setup. Here’s how to find your values:
- Threshold heart rate (cycling)Targets are given as a percentage of your threshold heart rate on the bike – the highest heart rate you can sustain for about 60 minutes. How to find it: after a good warm-up, ride a 30-minute time trial on your own as hard as you can hold evenly – your average heart rate over the last 20 minutes is your threshold HR. A chest strap gives the most accurate reading. Stopgap without a test: about 90% of your reliably known maximum heart rate on the bike (185 bpm → 167 bpm).

- Most services receive roughly the next 7 days at a time. The complete plan is in your Intervals.icu calendar.
- Intervals.icu calculates the target ranges from your values there (e.g. FTP, threshold HR, threshold pace). If you change them, upcoming workouts are adjusted with the next sync.
- During setup, the Aspect App checks whether your values in Intervals.icu match your plan. You resolve any differences with one click – in either direction, with a side-by-side comparison first.
- If you move a session within its week in the Aspect App, Intervals.icu updates automatically – and so does your device at the next sync.
- Zwift uses the values in your Zwift profile (FTP, 5K time). Enter the same values there as in Intervals.icu.
- Strength sessions appear in the Intervals.icu calendar with a description and planned duration. On your watch they only show their title. You’ll find the exercises in the Aspect App.
In the Aspect App you can also download bike workouts as FIT files (e.g. for Garmin, Wahoo, COROS) or as ZWO files for Zwift.

Frequently asked questions
How do I get the training plan after purchase?
Once we’ve received your payment, you’ll get an email with your personal access link. Use it to open the plan directly in the Aspect App – in the browser on your smartphone, tablet or computer. You’ll also receive your invoice by email.
How does the plan get onto my watch and bike computer?
Via Intervals.icu. Open your plan in the Aspect App, tap “Intervals.icu” at the top and follow the steps: connect your free Intervals.icu account, match your target values, choose your start Monday, check the preview and send the plan to your Intervals.icu calendar as structured workouts. From there, Intervals.icu sends the upcoming sessions to Garmin, Wahoo, Zwift, Suunto and COROS – to set this up, go to Settings → Connections in Intervals.icu, connect your device or platform and switch on the upload of planned workouts (e.g. “Upload planned workouts”). For Hammerhead Karoo, set up the connection in your Hammerhead account. Zwift uses the values in your Zwift profile (FTP, 5K time). Most services receive roughly the next 7 days at a time.
Does it work with the Apple Watch?
Not directly: there’s no official Intervals.icu integration for the Apple Watch. It’s only possible via third-party apps (e.g. Watchletic – the Intervals.icu import is a paid feature). Polar and TrainerRoad aren’t supported directly either. You can still see all your sessions in the Aspect App at any time – including in your smartphone’s browser.
Does Intervals.icu cost anything?
No. A free Intervals.icu account is all you need for the transfer. Intervals.icu also offers an optional supporter subscription – you don’t need it for this. Transferring from the Aspect App doesn’t cost anything extra either.
Do I have to keep my values up to date in two places?
No. In the plan view, the “Match target values” step (“Intervals.icu” button) checks whether Intervals.icu holds the same values as your plan – FTP, threshold HR, threshold pace or swim threshold pace (CSS), depending on what your plan uses. If anything differs, you see both values side by side, choose which one applies for each, and match them with one click. Nothing is overwritten without asking. To do this, you confirm access to your Intervals.icu sport settings once when connecting. Your indoor FTP stays unchanged, and HR zones are only recalculated if you explicitly ask for it. Zwift still uses the values in your Zwift profile.
Do I need an account in the Aspect App?
Not to view it: the access link also works without an account. With a free Aspect account, you save the plan permanently under “My plans” – and only then can you transfer it to your watch and bike computer via Intervals.icu.
When can I start the plan?
Whenever you like. The plan isn’t tied to a date but built in weeks (week 1 to 6), and each week starts on a Monday. If you have a race in mind, simply count back 6 weeks from race day. For the transfer to Intervals.icu, you choose your start Monday yourself – the Monday of the current week at the earliest.
What happens if I start later or need to reschedule?
No problem. If you want to start the whole plan later, simply choose a new start date in the plan view under “Intervals.icu” → “Reschedule” – the sessions are moved in your Intervals.icu calendar without any duplicate entries. If you no longer need the plan there, you can remove it again. Your own entries in Intervals.icu remain untouched. If just a single day doesn’t work, move the session within its week (see the next question).
Can I move sessions to other days?
Yes, within the plan week in question. With a free Aspect account, you can move a session to another day of the same week in the plan view or change the order within a day – by drag and drop on a computer, or via the “Move to…” menu on each session on a smartphone. The plan itself stays unchanged: moved sessions are marked with a small icon (e.g. “originally Tuesday”), and “Reset week” or “Reset whole plan” restores the original order. If the plan has been transferred to Intervals.icu, moves and resets are applied there automatically – and to your watch and bike computer at the next sync. If you move a transferred session within its week directly in the Intervals.icu calendar, the Aspect App picks this up (it can take about a minute). If a session ends up outside its plan week there, the app moves it back to its week and lets you know. Without an account, you can view the plan but not move sessions.
Is the plan tailored to me personally?
No – it’s a ready-made training plan that works for many athletes with a similar goal. If you’d like individual support, you’ll find 1:1 coaching at aspect-sports.com.
Do I have a right of withdrawal?
The training plan is digital content. With your express consent, it is made available before the withdrawal period has expired – your right of withdrawal then expires when provision begins (Section 356(5) of the German Civil Code, BGB). You’ll find the details in our withdrawal policy.
