What is Functional Threshold Power (FTP)?
Functional Threshold Power is the maximum average power you can hold for one hour.
Actually, it is very hard to do this kind of workout, it can be done just by well-trained athletes. Instead, you can do 20 min test describe below.
• Why FTP is so important?
Base on Functional Threshold Power we can build our training plans, set up training zones, work on specific energy systems and easier achieve our goals.
• How long I can hold my FTP?
Very well train athlete can spend even 2 hours around his FTP level. It is good if you can handle 2 x 20 minutes intervals at you Functional Threshold Power. Remember that you can spend just minutes being over your threshold and much longer being below it. That is the way it is so important to increase as high as possible.
• What tells you if someone’s threshold is 250 Watts?
Not much, I would ask what is his/her weight it gives me much more information if I can count his power to weight ratio. Example: Rider 1, FTP 250 Watts weight 63 kg and Rider 2, FTP 290 Watts weight 85 kg.
Rider 1: 3.96 Watts/kilo
Rider 2: 3.41 Watts/kilo
Conclusion: Rider 1 is a good climber but would have a lot of problems with Rider 2 on flat courses, criteriums and at the track.
Don’t always try to get the best power to weight ratio!
It is a very important aspect but not always valuable, depends on the type of cycling you are doing.

How to test (FTP)?
How to set your FTP or FTHR?
You do not need expensive laboratory tests. The very good way is to make a 20-minute test which can give you very decent results. Why do you need to know your Functional Threshold Power?
Most importantly to set your training zones, if you know them it is much easier to control your training plan. Below you can find instruction on how to perform the whole test. The average number of Heart Rate or Power reduced by 5 % is your Functional Threshold Power (FTP) or Functional Threshold Heart Rate (FTHR). Why we reduce numbers by 5 %? Because you should do a 60 min test, not 20 min, but it is much harder even sometimes not possible to do.
Remember to warm-up well.
Start very easy, get to your full speed about 2-3 minutes.
When you get your speed to push hardest you can to the end of effort being able to keep same speed, power.
Do not forget about cool down.
|Time||Description||% of FTP||% of FTHR|
|20 min.||Endurance pace||65||70|
|Warm-up||3 x 1 min. (1 min. Rl)||Fast pedaling, 100 rpm||N/A||N/A|
|5 min.||Easy riding||65||< 70|
|5 min.||All-out effort||max||> 106|
|Main set||10 min.||Easy riding||65||< 70|
|20 min.||Time trial||max||99 – 105|
|Cool down||10 – 15 min.||Easy riding||65||< 70|

How to Increase (FTP)?
To increase your Functional Threshold Power you have to spend time in this zone, to be more precise between 93% and 105% of your FTP. If your FTP is 280 Watts then you have a range of 260 – 294 Watts.
93% is “Sweet Spot” which is one of the best places to be to improve your FTP. You can try 3 x 15 min., 2 x 25 min. intervals and see if you can afford it. You can read more about interval training here.
Try 2 x 20 min at 100% of your FTP with 5 min. easy spin between intervals. If you are going to 105% of FTP try to start with 10 min. intervals first.
Always remember about recovery weeks every 3-4 weeks and testing your Functional Threshold Power every 6 weeks.
