Beginners Guide To Power Zones - 6 Power PBs

The process outlined in the previous section will give you a baseline of how fit you are, by zone. Changes in the wattage for a zone are changes in your fitness. You can expect of the course of a training period that the watts for each zone may go or or may go down. The only thing that you would not expect is that they all stay the same.

A straightforward goal during each season and year on year is to regularly retest yourself and see how you are progressing. If your watts are increasing in some or all zones then you are getting fitter. You should be riding faster and/or further as a result.

As a beginner it is fun just to aim to set new PBs for every zone. This will encourage you to try lots of different types of events which will widen your horizons and is a good way to find out what you are best at and enjoy the most. Once you become more specialised then some zones will be more important than others so you will need to be more selective. Still one result of this specialisation should be more rapid improvement in the zones you prioritise though it may also mean results in a different zone go down.

Mix your tests up, not just touching every zone but also changing either power or duration. 

Say you have plateaued at your zone 5 test. Just hit the reset button and try going another 5 seconds longer at the same effort or for 3/4 minutes at higher watts. That counts as a PB. 

This is great training in itself and will prepare you for times when you need to dig deep for longer or harder.

Also use these tests as opportunities to see what works best for you in terms of preparation. Some riders ride best following an easy day. Others ride best after a hard day. You will only find out what sort you are by trial end error (Graeme Obree failed by over a kilometre in his first attempt at the hour record. He barely slept overnight, came back the next day, rode the extra kilometre and more and set his first world mark).

These power targets do not need to replace other targets e.g. race placing or Strava. To the contrary they should complement each other. Improving your power will result in better places/times and going for places/KOMs is one of the best ways to test your power.

One advantage of tracking power PBs is that these are less subject to bad luck. Say you have set a target of going sub hour for a 25 mile time trial and have the misfortune to puncture in the first few minutes. The target is now impossible but that does not mean all is lost. You can fix the puncture and channel your frustration into setting a new power PB for the remainder of the race, aiming to ride above your zone 4 best for the rest of the distance. 

If you manage this not only will have the satisfaction as a reward but also the experience will be great preparation for you next 25. You may find that you have set a new PB for 58 minutes and averaged over 25mph in the process, so next time should be a breeze barring misfortune. Even if you try and fail it will be time better spent that just limping back to the start feeling sorry for yourself as you have learned about your limits and what improvements may be needed in terms of power and/or aerodynamics for the future.

An additional spin on power targets is to set them in terms of W/kg. If your target events include any amount of climbing and/or you want to lose weight this is especially relevant and can be an additional motivator. This way you win if you either increase your watts or reduce your weight and win double if you manage both. (Tools like bikecalculator.com can be used to give you a reasonable estimate of how long it will take to do a climb and can be used as an additional incentive if you have a trip planned with an special target climb in mind).
