So, here are six good reasons why we think you should seriously consider investing your hard-earned cash. (electronic chill music) - First up, having a powermeter is going to lead to huge gains in fitness. - Hold on a second, Dan. You can't just plug it on your bike and expect to do that. You need to learn how to train with one, analyse the data, and then use that data to form a personalised training plan. - That is true. But if you do do all that, I stick to my original statement. And I will give a personal example to back this up. I got my first powermeter at the age of 23. At that point, I'd been a full-time rider for four years and I'd been racing for over 10. Nevertheless, within the first 12 months of using one and training with it properly, I made a 10% improvement in FTP, which is pretty big. Secondly, powermeters make segment times completely irrelevant. You can set a new PB, bike power, instead of bike time. - Well, hold on a minute, Dan. You need to make sure that you keep aerodynamics and weight the same because even if you say you're 10 watt improvement in your power, it's not gonna mean much if at the same time you're gonna be 10 kilogrammes heavier. - That is very true. But if you do keep all those other factors the same, a powermeter is going to let you see the bigger picture. So if, for example, if you were slower on a particular part of your ride, but your power is higher, you'll know there is good reason for it. It might be you got a slight headwind. Or it might be that the air pressure was higher. Whatever the reason, you can be satisfied. For although you were slower, it was a better physiological performance. - Because power is absolute. - That's true. Speaking of which, the powermeter is a great tool to help you mentally deal with those types of conditions. I don't know about you, Matt, but I hate a headwind. In fact, when I was a lot younger, I actually cried to a headwind because it forced me below my average speed goal for the ride of 20 miles per hour. - Well, I used to hate headwinds, Dan. And I still do, but the good thing about powermeters, they allow you to keep a really good, even tempo. And like how last point, and not worry about the speed that that power produces. In fact, I use headwind sections to help me climb. - [Dan] Next up, a powermeter will allow you to go faster even without getting any fitter. - [Matt] Hold on a minute, Dan. Really? - Yes, really, Matt. Through pacing. So, a powermeter will enable you to ensure that you don't go in the red at the start of your event and pay for it at the finish. Through testing in training, you're going to know what you've got in the tank, and therefore, empty your tank at your event at exactly the right time. Whether that's 24 minutes or 24 hours. - powermeters give you a reference, allowing you to compare yourself with yourself. Which is really important if you're looking to make performance improvements. - [Dan] Now, you may be thinking that you've got a local test climb that allows you to do exactly that. But the beauty of the powermeter is that it allows you to compare efforts on unknown roads with the efforts that you do at home. It would also allow you to create a power profile. That will show you what your strengths and weaknesses are. And you'll even be able to compare your efforts with those of the pros. - A watt is a watt no matter where in the world you may be. And, no matter what the weather. - In the words of Doctor Andy Coggan, one of the pioneers of training with a powermeter, testing is training, and training is testing. And a powermeter allows you to do your testing out on the open road without the need to head to a laboratory. - [Matt] They're a great tool to track your progress and see if you're training is leading to improvements. And in conjunction with your heart rate, you'll also be able to see if you're making efficiency improvements. You can test your sprint, your ability on short climbs, on mountains, and in time trials, et cetera. - What we would like to know are your experiences of training and racing with a powermeter, both good and bad. You can leave them in the comments section down below. On the other hand, if you don't have a powermeter and you also have no interest in every buying one, please let us know why in the comment section just down below. - And if you haven't already subscribed to GCN, you're one stop short for all things cycling.
