Like many cyclists, I measure my cycling progression by either one or two metrics: distance and/or speed. I remember when I used do 10 miles per day every day and shoot for 50 miles per week. Seemed like every little rolling hill was a major leg burner and the wind! Oh my gosh, the wind! Going south on 107 was a blast but turning around to face the wind made me wonder if I could ride the distant seven miles back to the car. Well, I did make it back to car and that’s how I continued to measure my progress. Distance was the way to go. Eventually, speed started to creep in my metrics but that was later.
My first foray into something different was with the Powerhouse system from iBike. This was an innovative system to do structured intervals while cycling. A combination of iPhone case and the Powerhouse application that, when combined together along with your bike, would guide you through a fifty-four day plan of intervals and rest days. It would start you out with a fitness test to see where you stood and establish that baseline. Once you completed the fitness test it would then create a custom schedule of intervals for you to follow throughout the week. The application paired up with cycling coach Allen Hunter that guided and encouraged you to keep at it. It’s his formulas and techniques in training that is used to create that personalized training plan for you. How cool is that!
The program was simple, Allen Hunter would pop up and tell you what to expect for that days workout. It had a structure to it: a warm up, a set of intervals and then a cool down. All you had to do was keep up a certain cadence and keep a sliding arrow between the minimum and maximum range for that segment. The intervals varied from day-to-day and they were tough! You had to learn to change gears to keep that sliding arrow where the coach wanted it. Shifting gears up or down depending on the road conditions and winds was the name of the game. It was fun and challenging to go through the entire 54-day program. Throughout the program there were rest days and fitness test days to see where you stood and to make adjustments to the training program. Fun! When you completed the program you simply start over but at a higher fitness level.
The Powerhouse was my first experience with and training with a power meter. Yes, that’s right the Powerhouse system was in fact a power meter with all the numbers stripped out and a simple graphical interface was used instead. No mention of Watts, FTP, NP, VI or some other acronym was ever uttered. Total bliss. The case held the wind port and the sensors needed to measure the forces you were overcoming to pedal. The software on the iPhone used those sensors to compute the power and display it graphically. That sliding arrow represented the power you were exerting while cycling. That fitness test you was doing was the same fitness test you do to get your Functional Threshold Power (FTP).
I did improve. It was easier to ride against the wind, those rolling hills were a lot easier and my average speed improved. I find it interesting how I fall back to the old metrics for measuring improvement, distance and speed. Those are “feel good” metrics that we can easily relate to.
I now use a Newton Power Meter from iBike. It is just as accurate as any other permanent power meter but the big advantage with the Newton is the price and the fact that you can take it from one bike to another as easily as you could with a Garmin. The Newton has been on my bike for about a year now and just love it. The unit does have a few quirks such as no backlight, no bluetooth and no GPS but makes it up with having a great visible display in bright sunlight, long battery life, wind gauge, temperature and excellent power readings.
I’ve learned to do my fitness test to get my FTP and I’ve become familiar with the average power readings to expect on my rides. It does have Intervals built-in but they are not as easy to follow as the Powerhouse unit. The developers are constantly updating the firmware for the unit to improve and add new features to it. Bug fixes are free as well as minor enhancements. New major features means you will have to fork out some funds to enable it. That’s cool because you pay for what features you want. With the new enhancements I now have access to Nominal Power (NP) and actual power on the same screen. This really helps me pace myself depending on the type of ride I plan on doing. In my case it’s mostly endurance or long rides. No Time Trials for me.
As I mentioned before, I’ve set a weekly distance goal of 100 miles. I’ve started out at 50 miles and now it’s 100 but I’ve been thinking of increasing that. That is until I started using my indoor trainer to do some of my intervals. This trainer is not the usual mount bike and ride type of device but instead you can vary the resistance electronically through your PC or iOS device. The resistance is also calibrated and outputted in Watts to you electronic device. In essence I can now do structured power based intervals indoors (while watching tv of course)! Wahoo makes the trainer called Kickr and what a blessing it is. Combine that with the iOS app called iMobileIntervals I can do my rides, post them on Facebook, Strava or TrainingPeaks. Sweet!
Because of the Kickr, I have readjusted my thinking on those 100 miles per week. I used to struggle with deciding on whether I should ride on the Kickr or go cycling outside. I like doing the intervals on the trainer, but yet I’m not reaching my miles per week goal. It took me a while to get over the mindset that the miles HAS to be from cycling outside. That is just not true. Good quality miles on the trainer is just a good as being on the road. This was really hard to wrap my mind around but I’m starting to accept it.
Now my routine consists of intervals on the Kickr and longer rides outdoors where I focus on the target Nominal Power (NP) and reducing my Variability Index (VI) by pacing myself at the target power level. I don’t worry about speed or the wind. That will be taken care of as I get fitter and stronger. So far the results has been amazing. With the right pacing (even with the wind on my back) I can do the long rides without being burnt out although I do have to mindful of the 100+ F weather that we get around here in the Rio Grande Valley.
I’ve started brushing up on training with power and I got two books to help me on that aspect. Training and Racing with a Power Meter by Hunter Allen and Andrew Coggan and the other book is The Power Meter Handbook: A User’s Guide for Cyclists and Triathletes by Joe Friel. I’ve read the Joe Friel book and I need to go back and reread it again for better absorption. The Huner Allen book is there waiting for me to graduate to that level of understanding. Both books are great and highly recommend either one to anyone. I am definitely a beginner in this and have a lot to learn but I feel like I’m peeking over a tall fence and I can see the what’s on the other side, training with a power meter and I like it.
Share your experience with your early years of using a power meter. I’d love to hear from you.
