This Christmas I made a decision one of the best ways to have a good time the start of Jesus Christ was to inflict a considerable amount of ache on my particular person by doing 5 completely different FTP (practical threshold energy) checks. This may not solely atone for any seasonal gluttony however would resolve a bone of rivalry that has been dogging biking for the previous 25 years: which check is the most effective?
By definition, FTP is the facility a bike owner can maintain for an hour. After getting ascertained this determine, it may be used to calculate your biking coaching zones after which create a biking coaching plan to enhance your health. The quantity of energy you’ll be able to maintain for 60 minutes is set by metabolic effectivity – your physique’s means to show gasoline into power – and corresponds to lactate ranges. Pedal too exhausting for too lengthy and your physique’s engine room runs into bother: it will probably’t shovel coal quick sufficient. Fatigue quickly units in, and it’s goodnight Vienna. The quantity of energy you’ll be able to maintain for a comparatively very long time – an hour, particularly – is due to this fact an essential benchmark.
Having sought recommendation from a few of the sport’s main authorities on discipline testing: former WorldTour rider and coach at Thighsclub.com Alex Dowsett, coach Chris Carmichael, and home racer Andy Critchlow, I slipped away from a Boxing Day sport of Scrabble, pulled on a pair of bibshorts and waddled with trepidation in the direction of the shed.
WHY FTP TEST ACCURACY MATTERS
An correct FTP studying lets you practice in particular biking coaching zones on the right depth. Coaching at too low an depth sells your efficiency brief, whereas coaching at too excessive an influence might result in burnout and even damage. Right here’s tips on how to calculate your zones based mostly on FTP:
| Zone | Depth | % FTP |
| Zone 1 | Energetic Restoration | Row 1 – Cell 2 |
| Zone 2 | Endurance | 55-75 |
| Zone 3 | Tempo | 76-87 |
| NA | Sweetspot | 88-94 |
| Zone 4 | Threshold | 95-105 |
| Zone 5 | V02 Max | 106-120 |
Pacing: Realizing your zones permits a clearer understanding of tips on how to tempo efforts and races over various instances and distances.
Progress monitoring: Supplied it’s re-tested each 4 to 6 weeks, FTP is a good barometer of health.
Lactate coaching: Coaching at threshold improves the physique’s means to shuttle lactate, utilizing it extra effectively as a further gasoline, that means hydrogen ions accumulate extra slowly (it’s the latter which can be thought to trigger ache).

TEST 1 THE HOUR OF POWER
(Picture credit score: Future)
ALEX DOWSETT SAYS: For almost all of individuals, really emptying the tank at a uniform tempo over an hour – particularly in case you’re doing it indoors – is probably probably the most psychologically demanding issues you are able to do on a motorbike.
MY TEST: Embarking on an hour all-out could seem to be a frightening prospect, however right here’s the factor: you agree in to a sustainable tempo fairly simply. Maybe too simply. The most important hazard isn’t blowing up however promoting your self brief. Conscious that my 20-minute greatest was 370 watts, I tried to dwell inside a 10-watt window between 330-340 for the period. Mentally breaking the hour into 4 15-minute sections, the plan was to set a strong basis within the first and second blocks, restrict inevitable harm throughout the third, and spend the ultimate block merely attempting to not die. The ache started to manifest in earnest at across the 28-minute mark as I attempted to inform myself ‘Ah good, solely 32 minutes left’ whereas secretly hoping {that a} kindly gust of wind would rip the shed down from round me. I completed the hour of energy with an output of 335 watts, having hit a max coronary heart charge of 189bpm. I used to be moderately happy, however the truth I used to be in a position to persist with the parameters I’d set myself previous to the check instructed that I might’ve maybe gone out slightly tougher. There was no experimentation right here – I set a quantity and caught to it, which was probably not greatest apply when the intention was to rid myself of each accessible morsel of power.
RESULTING FTP: 335 WATTS
TEST 2 THE RAMP TEST
ALEX DOWSETT SAYS: That is the simple one. Consider it as 5 minutes simple, 10 minutes uncomfortable, and 5 minutes disgusting. Ensure you empty the tank. The extra you need it, the higher your end result…
MY TEST: The ramp check was the one I used to be least afraid of – however that’s to not say I used to be wanting ahead to it. Whereas the hour of energy could be billed categorically as a slow-burner, the ramp check sits on the different finish of the spectrum. One minute you’re turning the pedals with out a care on the planet, the subsequent you’re throwing up items of your proper lung. It’s a check that very a lot favours these with high-end oomph. It’s brief, sharp and tends to provide flattering outcomes, therefore its recognition.
The ramp check begins in a deviously unassuming trend at simply 100 watts, the facility growing in increments of 20 watts each minute till your physique and thoughts throw within the towel. Your FTP is measured by taking the best one-minute energy reached – AKA your maximal cardio energy (MAP) – and multiplying it by 0.75. This calculation does produce discrepancies between riders, but it surely’s extensively used amongst coaches and on coaching platforms for a fast technique of ascertaining the allimportant determine.
My ramp check lasted simply over 22 minutes (together with a five-minute warm-up). Minutes 18-20 discovered me in uncharted territory at over 400 watts, attempting to trick my mind into believing that, regardless of the dribble, this was sustainable. Throughout minutes 21-22 ‘thoughts over matter’ not utilized – I’d no thoughts left. My mind had buggered off midway by the 440s and I used to be counting on muscle reminiscence to get the job accomplished. Lastly, 460 watts and out.
This produced an FTP determine of 348 watts – 12W greater than my hour of energy. Might I actually maintain 348 for an hour? I’d have to search out out. However first I had two extra checks to finish.
RESULTING FTP: 348 WATTS
TEST 3: 20 MINUTES ALL-OUT
(Picture credit score: Future)
DOWSETT SAYS: In the event you get the primary 5 minutes proper, the subsequent quarter-hour take care of themselves. Begin out at your earlier FTP end result and gauge your kind – then you’ll be able to push above it, in case you’re on an excellent day.
MY TEST: In all probability the preferred manner of estimating FTP, the 20-minute check has been haunting coaching calendars since circa 2010. It’s fast and it’s sensible, sure, but it surely also needs to be within the dock at The Hague for crimes towards humanity. That is the massive one, to my thoughts, the check that yields essentially the most discomfort. Designed as a method of truncating the hour check, the 20-minute check’s energy is multiplied by 0.95 to calculate FTP.
One thing fairly extraordinary occurs if you’re endeavor an FTP check over this period. The principles governing the space-time continuum grow to be distorted; a minute not includes 60 seconds, it now has carte blanche to final for so long as it rattling properly pleases. I took this negativity – nay, concern – into the third check of the sequence.
Eleven minutes in and I’d managed to decide on a wattage of 380 that, whereas eliciting a profoundly furrowed forehead, was nearly manageable. I lived right here now – in a burning scorching bedsit with the satan knocking on the door. The second hand ticked by with all of the urgency of a narcoleptic slug, however 18 minutes materialised and a glimmer of hope started to play on the digital horizon. The tip was in sight. It was time to empty the tank.
With a median energy of 379 watts, I hauled myself out of the saddle, winding the facility as much as 382. This yielded, after deducting 5%, an FTP of 363 – and a big gulp as I realised the bar had been raised considerably, with one other check to go.
RESULTING FTP: 363 WATTS
TEST 4 2X 8 MINUTES
CHRIS CARMICHAEL SAYS: This can be a check you’ll be able to schedule in comparatively simply with out a lengthy taper. Do it after a day or two of simple driving. Because the athlete good points extra cardio conditioning, the hole between the primary and the second eight minutes begins coming down.
MY TEST: The final of our checks is maybe the least orthodox. warm-up is adopted by two blocks of eight minutes separated by a 10-minute relaxation. The intention of the 2 instances eight minutes is to don’t have anything left within the tank after every effort. The primary must be accomplished as if the second didn’t exist; no muscle fibre must be spared. The second interval must be as shut as attainable – when it comes to effort and energy – to the primary. FTP is calculated by discovering your common energy for the 2 checks and multiplying by 0.9. This check fits these with a excessive anaerobic threshold – puncheurs, crit racers and cyclocross specialists. I don’t boast the credentials of any of the above and I set off on my first tour into the unknown with trepidation.
My ways for this check had been easy: head down, watts up. Eight minutes isn’t that lengthy – let’s go bonkers! I didn’t have a look at energy or time for at the least 4 minutes. Nevertheless, when a fast look up confirmed that solely 28 seconds had elapsed, it rapidly grew to become obvious it was going to be a type of days. I closed my eyes and tried to discover a completely satisfied place. For a few seconds, I used to be on a seaside in St Lucia sipping a Singapore Sling, however then a northeasterly gust rattled the window and I used to be again in a chilly shed smashing out eight minutes at 415 watts. The jubilation of finishing such a activity was short-lived as a result of 10 minutes later I used to be again on the coal face counting down the minutes, watching my coronary heart charge soar and readying myself for an additional hateful eight. I mustered 385 watts for the second interval and was greeted with my newest FTP calculation.
RESULTING FTP: 360 WATTS
The outcomes
FTP STATS THAT MIGHT SURPRISE
450 watts: the estimated FTP of Tadej Pogacar (6.8W/kg)
80-85%: FTP as a proportion of VO2 max
323 watts: reported FTP of Olympic champion Kristen Faulkner (5.2W/kg)
1-2%: annual decline in FTP after age 40, except doggedly maintained
4.6-5.3W/kg: FTP ranged rated ‘wonderful’ for newbie males, in keeping with the well-known Andy Coggan chart
4.1-4.7W/kg: FTP vary rated ‘wonderful’ for newbie girls
So the outcomes had been in: 335, 348, 363 and 360 watts respectively. In the most effective case situation, I’d be capable to maintain 363, the best determine, for a full hour. It was time to search out out. Had psychological weak point held me again on that first ‘hour of energy’? Might I actually enhance it by practically 30 watts?
I rested – properly, actively recovered – for 2 days previous to what, on paper, bore all of the hallmarks of a totally rotten night within the shed. My thoughts wandered again to my first hour of energy once I’d ridden on a knife-edge at 335 watts by sweat, tears and wild-eyed desperation. As for having to repeat it, my mind had pixelated that specific piece of data – I simply refused to consider it. Till now.
With a goal of 360 watts, I took a deep breath and engaged my energy meter in what would grow to be our most bloody battle but. We exchanged blows relentlessly for the period, however a remaining volley of high-torque hooks floored my nemesis and I walked away from my second hour of energy having averaged 358 watts (equating to 4.0W/kg). The battle was over and I’d managed to assert some territory.
Consistency guidelines

So, the query is, which check is greatest? Or moderately, which one elicits the determine closest to real greatest hour energy whereas requiring a a lot shorter period of ache? For my cash, the ‘two instances eight minute’ check takes high honours – my results of 360 watts turned out to be simply two watts above my remaining hour of energy. That’s spectacular accuracy for a check with solely 16 minutes of effort. That mentioned, you do in fact must be absolutely dedicated to squeezing out your absolute best energy throughout every eight-minute interval, particularly the harder second one.
The ‘hour of energy’ ensures you’ll uncover your real hour energy however, as I proved, it’s comparatively tough to tempo and will require a number of makes an attempt. The normal 20-minute check takes second place and is very recommended for producing a determine solely 5 watts greater than my real hour effort. The principle takeaway is that each one these checks are robust, and you might want to go into them with dedication. You might be stronger than you assume! When you’ve determined in your check, that’s the one to stay to for the yr, making certain consistency throughout your re-tests. Dig in, dig deep, and go smash out your greatest FTP but.
