Lactate · INSCYD · In person in Spain

Performance testing for cyclists

Lactate and INSCYD testing in person in Spain, at our usual testing locations or at one of our camps. Your results become training zones and decisions in your coaching plan.

LT1 and LT2, measured directly in your blood
INSCYD metabolic profile: VLamax and how much fat and carbohydrate you burn
In every coaching plan: INSCYD testing at a discount, one test a year included in Full-Service

What you get

A test that measures what sits behind your FTP

Testing is optional and is used where it helps your training decisions. It is part of your coaching: your coach turns the results into your zones and your plan.

The test

A step test with small finger-prick blood samples, plus a short sprint
On the road, on a steady climb: if the weather is bad, we test indoors on a smart trainer
In person in Spain: at our usual testing locations or at one of our camps
The lactate data gives a full INSCYD metabolic profile

Our approach to testing

Fewer guesses, better training decisions

Most riders train by FTP alone. A test shows what sits behind it, and your coach uses it to set your zones and decide what to train next. Between tests, your power data and your own measurements keep the picture current.

Lactate

Lactate is the purest physiological marker we have. We measure your LT1 and LT2 directly in your blood.
INSCYD

The lactate data gives a full INSCYD metabolic profile: VLamax and how much fat and carbohydrate you burn at every intensity.
On the road

We test on a steady climb, in real riding conditions. If the weather is bad, we test indoors on a smart trainer.

Always in person in Spain, at our usual testing locations or at one of our camps.
Your own samples

If you take your own lactate samples, we can analyse them wherever you are.

Performance reviews them twice a season; on Full-Service they are used on an ongoing basis to adjust your plan.
Power data

Your coach reviews your rides in WKO5 and adjusts the plan in TrainingPeaks, so your zones keep working between tests.
Breathing and heat

Breathing rate (Tymewear) and core temperature, with heat and BFR training, on Performance and Full-Service.

Jānis is a CORE certified coach.

Results

Coaching built on physiology, at every level

Testing is one of the tools behind our coaching, not the whole of it. We coach everyone from riders preparing for their first gran fondo to Olympians.

What athletes say about coaching with data

A personalised training plan, adjusted so I can develop and work on my weak points, based on both physical and biological markers. Up-to-date training methods, on and off the bike. On top of that, I can get all kinds of information on training topics, such as nutrition, the body's biological processes, training details and explanations of terms.

Egils PeļņiksTrain2Win athlete

The training process was very clear and purposeful: the direction was always clearly set, and any problems or mistakes were solved quickly. I really value the individual approach and the data analysis, which helped me see my progress, and the chance to try different disciplines, from TT to gravel, which kept training varied and interesting.

Nikolajs BumanisExcerpt · road and gravel · coached by Jānis

I really appreciate that Dana doesn't stop at writing a training plan but looks at the whole person. She asks about my health, digs into my blood test results, keeps track of my health markers and also gives advice on supplements and vitamins.

Questions

Performance testing: common questions

Is testing included in my plan?

Only in Full-Service, which includes one INSCYD test per year, 30% off further tests, and one INSCYD analysis of your own lactate data per year. Core and Performance get 10% and 20% off INSCYD testing. Testing is optional and is used where it helps your training decisions.

Where are the tests done?

In person in Spain, at our usual testing locations or at one of our camps. We test on a steady climb; if the weather is bad, indoors on a smart trainer. Coaching itself is remote, so you only need to come to Spain for the test.

I live far from Spain. Can you still use lactate data?

Yes. If you take your own lactate samples, we can analyse them wherever you are. Performance reviews them twice a season; on Full-Service they are used on an ongoing basis to adjust your plan.

I already have data. Can you review it without coaching?

Yes, with the Elite Performance Audit: a one-time, in-depth review of your data by Jānis, with a recorded video analysis of 40 minutes to an hour, a written summary based on it and a video call that ties everything together. €749 — one-time, all-in. If you start Performance or Full-Service coaching within 60 days of receiving your video review, we credit €100 against your first month. About the Audit →
