VO2 Max Booster Program – VO2 Max Test

Welcome to my series: VO2 Max Booster Program
This training program will dramatically boost your race performance in only 14 days. The training program can be used by any cyclist, but riders with a SRM or PowerTap mounted on their bike will get the best value.

Whenever you begin a new training program, it is good to know your starting point. It makes it easier for you to track improvements and evaluate your training routine.

Maximum Power Test

Before you start training for VO2 max improvements, it is a good idea to do a five-minute all-out test to estimate your average watt at maximum oxygen consumption. There are other tests, but I think this one is so simple, easy to use and very reliable. You can do the test on a stationary bike or on the road if you are the lucky owner of a power meter.

Once you have performed a five-minute all-out test, you can begin to train, and when you have trained for a couple of weeks it will be easy to monitor your progress.

On Day 1, you will have to do a test to figure out what your starting point is. The best way to do this is to perform a VO2 max test, e.g. five-minute all-out test. Most people can maintain their VO2 max for about 3 to 8 minutes. So a five-minute test will come close to VO2 max for most people. Notice how many watts you can perform.

If you do not have a power meter then use an ergometer bike. If power meters or ergometer bikes are not available, then you can perform the test on a track or a steady hill to see how far you can ride in five minutes. But I highly recommend you do some kind of power monitoring.

Please Notice These Values When Testing

  • Power Output. The most important measurement in a power test is power
  • Body Weight. It is important to notice your body weight when you do the test because it influences your performance
  • Heart Rate. It is also recommended to wear a heart rate monitor, so you can evaluate whether you pushed yourself harder in the VO2 max test after finishing the VO2 Max Booster Program
  • Temperature
  • Time of day

Day 1
Total time: 1hr training
20min incremental warm up
5min easy rolling
5min VO2 max test
30min Easy/medium rolling

Now it is time for you to enter the VO2 Max Booster Program by performing the 5min test as the first step out of 14 steps to a higher VO2max. Good luck!

Next step: Day 2 – Intervals Targeted For VO2 Max

The entire VO2 Max Booster Program is included in my e-book Time Effective Cycling Training.

    Is there any way to correlate wattage during this test with a VO2 Max value? e.g. 300W = 62 (ml/kg/min)

  • Thanks for this post. I’ll be starting my VO2 Max Booster Program this week.

  • Anthony Link

    I don’t know if you can use the value from the VO2 Max wattage derived from the test on this site (could work out to be the same), but have a look here:


    and scroll down to the section about the outdoor VO2 max test.

    It describes a protocol (four minute stages starting at 110W and increasing by 35W every four minutes with one minute recovery between each increment) where you can take the wattage of the last completed four minute stage before you reached failure and use a formula to estimate your VO2 max value. The formula can be found at that same link. I haven’t tried the test here yet, but am interested to see if the wattage is similar to my wattage in the test described in the link about.


  • Increasing power output with 35W every 4th minute is not optimal when you want to test your maximal oxygen uptake. These small increments in workload increase the risk of failure before you hit VO2 max.

    If you want to do tests like this it would be better to use increments of 35W every 2minutes. This is scientifically shown to be the most secure way to reach VO2 max.

  • Hey
    Just to get the vo2max test right…
    I give it all I can for 5 minutes, and my vo2max is the average Watt output?
    Is that right?


  • Jonny,

    It’s 5min allout. Your average power estimates how much power you deliver at VO2 max.

    Enjoy the program!


  • Smythy Link


    Looks like a good starting point for me. I would also like to know if i can still do my base km at the same time. I know it will take a lot out of me but i am on holidays currently and need to also do the base km for later in the year.


  • David Link

    Sorry for the basic questions, but have a couple regarding VO2 Max Booster:
    Can you describe the incremental warm-up in more detail?
    With a heart rate monitor only and no power meter can the % of V02 Max for intervals be translated into % of max or avg heart rate?

  • David Link

    Hi I ran the Test (Indoor)and managed 360W for the full 5 min at a max 181hr now what do i do next?


  • Next step: Day 2 – Intervals Targeted For VO2 Max 😉

  • David Link

    lol Thanks!!! 🙂

  • Mike Link


    Thanks for this program. I did the 14 day VO2 Max effort about 2 months ago and saw amazing improvements. I am contemplating doing a second round of VO2 Max. Is there any guidelines for frequency of this program?


  • Rasmus Velling Link

    I am currently not able to afford a power-meter, but own a fantastic heart rate monitor aswell as distance/pace computer. Is there a way to convert your suggested intensities into heartrate or pace?

  • Jim Link


    I completed the 14-day VO2 Program. I was hoping for a better result, but I think I made some mistakes in my after program test.

    My weight is 72kg.
    My Day 1 VO2 was 309W. (I did this on my trainer)
    I completed all the workouts per the plan. On almost all the efforts I was 10 – 15% above the target wattage. Day 12 was hard, but Day 11 was toughest for me (I think because I did it on the trainer).

    So, after Day 14 I took a day off and then did a couple days of easy riding. Then I had to make an unexpected trip and couldn’t ride for two more days. So six after finishing the program I attempted a 5min test, but after two days of not riding I could tell it wasn’t happening. I aborted the test two minutes into it. I did the test the next day and averaged 323W. I didn’t do the test on my trainer and the terrain wasn’t flat. I had a hard time keeping my wattage up on a slight downhill section. Through this section and after my heart rate was high. My wattage graph has a definite U-shape (strong at the beginning and end, weak in middle).

    That being said I feel stronger after this program. Not only at VO2 but also at FTP. I’ll find out this Saturday during the weekly hamerfest.

    Thanks for the great site,

  • Kev Link

    I am nearing the end of a 4 month period of increasingly hard training, for an ultra endurance mountainbike race on 21st August.

    This is my peak training week (19/7) ; I was then planning on light week next (26/7) to recover. The training volume in recent weeks has been high, i.e. 256miles/10,385m ascent last week, 12,000m ascent planned this week.

    My question is, would I see benefits from using the VO2 max booster program for two weeks from the 1st week in August. Could this effectively be the start of my taper, given the reduced training volume, or would one week to recover after the booster programme not be sufficent time to recover?

    Thanks in advance.


  • Mike Link

    I have done this training program twice now and have found it quite beneficial. I do my training on a computrainer and have each day as a course file. I set up a spreadsheet which calculates the wattage set points for each days effort based on the initial testing result. Then I edit the wattage values for each day as determined by the spreadsheet. I would like to offer to share these files to help others as you have helped me. If anyone is interested in these files I can share them. Contact me at wheels.msl@gmail.com.

    Thanks again,

  • Mhamed Link

    Hi there,
    I’m about to start my new season with the 12 Week winter Training program and i would like to ask you whether to start rather with the VO2 boosting program or apply it after ( in some 3 months).

    Thnx a lot in advance.

  • ian humphreys Link

    Hi Jesper, seems to be very effective. I managed all sessions exexpt the 2×3′ full gas, cracked with 15” of the last effort. All the training was done on the computrainer in coaching software, you write the file and the computer loads the resistance, the test was also done in this.
    I had two easy days and had to test as i did not want the to test too close to race day. I am aged 56 and managed the volume fine, in fact the fartlek session i just made an amalgam of everything i had done in the past days with minimum effort of 50% of 5’power turned out to be the most challenging.
    My race, I ride 2k 2.25, however the SC champs were over 3k with 2 rides, legs felt bad on Saturday, on Sunday race day fine. I recorded a 3.53 in qualifying and in the ride off for bronze went for it recording 3.47 winning the ride off by 4”. My time was even faster than silver. Historically I would ride 1”-2” slower in my second ride, but to go faster by 7” unbelievable.
    During some of the training I did felt like around lap 6 when breathing kicks in, and thought this is what i need, ok power was a bit lower but you were exercising you Vo2. Very pleased, Pete rode fantastic
    Many thanks, Ian Humphreys

  • Wabs Link

    Do you have any tips for cyclists that are not using powermeters? I read in your other articles that it is not possible to do such training with hart rate monitors because the reading will not be accurate for short intervals. Is it better for cyclist with hrm’s to skip this kind of training?

  • Jason Link

    Wabs – I’ve done this program before with a HRM and on the shorter intervals I just used perceived effort to gauge the intensity. If a 30 second interval feels too easy, just go a bit harder on the next one. If you’re still breathing hard at the end of the recovery, ease up a bit on the next hard interval. It won’t take long for you to hit the right intensity. If you’re doing the program on an indoor trainer, you can also use your speed (or gear & cadence) to judge the intensity. The power required to spin the trainer at a given speed should be fairly constant.

    In my opinion, it’s better to do this type of training at a slightly wrong intensity than to not do it at all.

  • Dickie Link

    Hi Jesper

    I will definitely be doing the VO2 program this year- but how long should I leave after the two weeks is complete to see the effects of supercompensation?

    Thanks for the site and ebook- you have really helped simplify training concepts for me

  • Phil Link

    I have done the VO2 max booster program for the 5th time. I spread it out for 21+ days and incorporate weights 3 days a week and high end Versa Climbing 2 to 3 days. I work off of my indoor trainer that has a power meter. First test was 440 watts, then 465 then 490, then 515. I will test out on the 5th one next week. I really enjoy the training as I only get outside to ride with the group 1 day a week and when I do I count it as a workout on your 14 days.
    I did do one 45 min time trial test (on the trainer) after the 4 time thru and averaged 407 watts for the 45 minutes.
    Your training really works for me as long as I take a week in-between sessions to recover. Those weeks I just Versa Climb.
    Thanks for your help

  • Craig Link

    Well i was very sceptical at doing this program, thought it would be too much, the first week i found i was quite tired but got better as i persisted, i timed my provincial race for day 9, it was a 4 lap race of 28km per lap, i suffered well, ended up eleventh which was good for me, finally finished the program, did a race this past sunday, i found when the group put everyone into the gutter, i didn’t seem to suffer like i usually did, my recovery after efforts was great, in the last kilometer i positioned well coming through a tight corner in 3rd place however i was pushed out by one of the big teams coming into the finish, i was basically pushed out into the wind which didn’t help my sprint, came in a disappointing thirteenth, however i must say this program has definitley helped me with recovering faster after intense efforts, will do the test again and start the program once more, Cheers keep the rubber side down

  • Lingi Link

    Dear Jesper,

    I would like to do the VO2 Max Booster programme.

    My question is how to do it without a power meter. I only got a HR monitor.
    Thanks & regards,

  • Paul Forster Link

    Completed the VO2 Max Booster Program for the first time. I weigh 140lbs age 37 and managed 245 watts first time around. The rest of the programme felt relatively OK over the training period with my heart rate topping out at around 92% of a maximum of 190bpm. Course completed indoors on a Tacx VR. Second fit test done and managed 285 watts, that’s a 16.5% gain! Took a two week break in Majorca and covered over 1000 miles for which I felt really strong. Had a 3 days rest and started round 2 of the programme. Thanks for the great programme, it really works for me and I can recommend it to all who can discipline yourselves to improving and not just heading out peddling with the crowd.

  • thomas Link

    Now on day 4, great feeling
    I just feel already it works! and will work!!

  • Oz Link

    Dear Jesper,

    I mainly do sportive rides (70Kg, 38 yr) and I use a power meter for pacing.
    I would like to follow your programme but ideally split over 3/4 weeks as I need to put in some long rides, any suggestions on how to best divide the workload over a month? (I guess the gain will not be of the same magnitude)
    Many thanks for your help!

  • Karsten Link

    Hey Jesper
    I am now Half Way through the program and I am really enjoying the the intensity of the workouts and the Extra free time.
    I travel 3 -4 weeks per year. What is your opinion om executing the program for these weeks of traveling by running instead of cycling? Would That benefit my cycling?
    Best regards

  • Ron Link

    Im going to participate in a race August 4 2012. I consider to implement your booster program as a preparation for this event. My 5 min watt is 405 w and do you think I need to do any adjustment to your program to benefit from it?

  • Craig Link

    Hi Jesper,

    The 12 day VO2 Max booster program looks awesome! Im an avid racer really looking to get my intensity as high as i can. Intervals are obviously the best way to do this… problem is, im not fortunate enough to have a power meter & therefore find it very difficult getting the results im looking for. I do have a HR monitor, but cant seem to find a program developed around HR & not based on power meters.

    Any help will be appareciated!

  • Ish humphreys Link

    My back was against the wall, eight weeks to the world masters track championships and I was struggling. The garden was becoming overgrown, I decided the masters was a no no, gardening was the focus. Three days full gas with the felcos and a glass of red things were looking better.
    Manchester was again the main focus , only 5 weeks, 2 weeks of hit 30″/4’x 8 every second day, then 14 days vo2 booster, one week taper using the reduced volume vo2 sessions and complete rest…….Manchester World Masters Ride off for gold. I was beaten in the final by a rider who was the defending champion, world record holder, not too shabby given the position I was in 7 weeks ago!
    Once again I would like to thank Jesper for the e-book which has produced the results twice, really happy despite not winning, Jim Host was just much better on the day.

    Yea I plan to do my fitness test fist thing in the mornig before work .And plan to comment on my results tomarrow night .

  • Ronald Link

    Well friday mornings test sucked I could not get the machine to do what I wanted it to do .So I had to go to another YMCA 40 Miles away and they had what I was looking for. The name of it was a Keishner and it showed watts and cadance . I was impressed after warm up and spin down to 65% I did the 5min test 450- 475 Watts and recorded my heart rate with my Polar CS500 ,Ave heartrate after the first minute was 182. hi was 190. So I cooled off for spin down to 60% about 10 mins and started the 30min test I could hold 360-375 watts I did see 440 a couple of time heart rate ave 185 after the first 20mins and on the last 20second I put the machine in the in high gear and tried to sprint it out 491 watts max heart rate 194 ,very low cadance on the sprint about 55 rpm .My weight all week has been 172 but it was 175 when I woke up this morning and I did fell a little bloated or maybe fully hydrated .This is my second week of this VO2 MAX Intearvals .I can say this program Rocks for me .I can stand on higear and tach out.11/28 39/53

  • Marco Ceia M. Link

    Hello Jesper
    I have a question, and as I define zones and % of power (watt)?
    Is there a program that knife me this?


  • Ronald Link

    Is there a way to estimate V02 MAX based on HR and watt ave and miles on a bike.
