Comparison test:
…and…
 
This weekend I wrote about the first ride PowerCal (see here).

Now, I have more data about these rides.
I did 4 rides of varying distances, on two different bikes, each with different profiles, and I compared the power readings by capturing them on two separate Garmin units pictured above.
On this weekend’s post, I made a numerical comparison between the rides, by comparing the power average, normalized power and TSS calculation… This time, I’m focusing on pattern comparison.
The objective was to identify the power pattern exhibited by PowerCal and …

UPDATE: There is a new post on PowerCal vs PowerTap comparisons.
…and…
About a year ago, CycleOps announced a revolutionary new device that would allow the calculation of power output during a bike ride through wearing a heart rate strap and nothing else. Back then, I wrote about it, and I was very skeptic.
Power meter product for cycling usually measure the force produce by the cyclist by using strain gauges on the crankset, on the pedals or on the rear hub.
The crankset based products, like SRM, Quarq and Power2Max, have …

July 2012 UPDATE: I have now made a review and comparison of PowerCal. See my new post with detailed review and powertap comparison here.
One of he big, and most surprising product announcements from Cycleops two weeks ago was the all-new PowerCal heart rate monitor.
This new device is an ANT+ heart rate monitor strap with a twist… Based on your heart rate, it derives the power you are producing. This is a very surprising announcement from a company that is almost a standard and helped open up and democratize the power …

This Friday was time for another training ride.
A ride from Harmarket Bycicles parking lot, for a fast route on route 55 to The plains then heading northwest, with the famous loop around Frog Town – Rectortown – Atoke – 50 – Zulla.
This an awesome 17 mile loop with extensive flat sections that allows a very fast loop for sustained Z4 training:

 
The complete ride was 46 miles long looks very funny on the map, but it’s a great training circuit with a mix of long fast sections with some long, but …

Hello everyone,
After spending last Sunday doing the hardest 50 miles on Skyline, starting from the gate, all the way up to Big Meadows, I started wondering how does this ride compare to all the other rides we’ve done over the last few years.
In doing so, I’ve created the all-new R3Q factor. What is the R3Q, you ask? It’s the Rodrigo Ride Rating factor !!!
The purpose of creating and using this factor is that it allows me to compare any two rides and evaluate how hard (or easy) the ride will …

Critical for any cyclist, or in general any endurance athlete is determining the training zones. The most common way of measuring and identifying training zones is by power output and heart rate.
Power output is very specific to cycling and requires a bicycle equipped with a power meter. Heart rate is simpler and more generic, as it applies to cyclist as well as any other type of endurance athlete, so it’s ideal for tri-athletes, as it can be used both on the bike as well as on the run (even in …

I’ve been watching and evaluating rollers for a very long time, but never pulled the trigger on any of them. I have a Kettler Ergoracer GT spinning bike
   
as well as the Computrainer for my bike.

Both provide great entertainment and fitness for indoor riding, but… I don’t use them much. In spite of the fact that both allow me to do virtual racing, I still get bored and never find enough motivation to use them at home.
Rollers are said to be more road-like, and provide …

Today, it was a new ride… well, rather an extension to a very well known ride.

The typical ride starts at the Warrenton gateway trail end at Old Meetze rd, and loops to Calverton, then Casanova… Today, I decided to add 10 miles, extending the ride until elk run rd.

 
The weather was still nice, but it was a bit nippy, sign that fall is coming toan end, and the cold days of winter are just around the corner…

This loop was done in solo Time Trial mode, and I tried to maintain …
