I made the plunge and bought a used PT SL off ebay, it is to arrive today. All the BF victories last year by those training with power convinced me of the benefit. Should be interesting as I've predominantly trained with perceived exertion in the past and recorded HR as a biproduct of effort. Last season family and work developments really limited my training time, and this hasnt changed, so I'm hoping the power thingy will help me and my coach really get rid of the junk, optimize my training, and direct me to race to my strengths. :)

Now, fellow BF members please be prepared for a thousand ?s on how to install, set up, record, turn on and off, and use this device ... and the charts, I'm going to need to learn how to post the charts!

Congrats! I've been training without even a recorded HR, and I'll be building my PT SL tomorrow night. Big changes ahead :D

I'll piggy back on your questions...

Do you use excel? Perhaps at work?

If you don't, I suggest changing careers to a job that has you using excel 40 hours per week. You'll get pretty good at the charts.

Mine just came in yesterday as well, also off ebay. I'll be joining you when it comes to the barrage of posts. Installation was super easy and I was finding out how wussy I am right away.

Hey, what's the program most everyone uses for uploading and using the data from the PowerTap? Is there a comparable (or better) program for Macs?

cslone
11-29-07, 02:22 PM
Cycling Peaks if you can find a program to make it run on your Mac.

mkadam68
11-29-07, 03:06 PM
That's right. I couldn't remember it's name. Most new Macs can run Windows programs. Unfortunately #1, I own an older Mac. Unfortunately #2, the software I use for analyzing Garmin data is better on the Mac (Ascent--don't mind plugging it here as it is awesome) vs. any PC offerings.

Are there any command-line/one-click programs out there that will just download off the PT and save it directly to a file?

I'd prefer to use my own spreadsheet/logging (etc.) and was wondering if there was any quicker way to get raw data other than opening some program, importing it, naming it, exporting it, and then finding the file.

I searched around and found mention of a ptapdl.exe but I haven't been able to locate anything like it.

You could just dload it with poweragent (native PT software) and export the CSV. I use the CSV for a certain type of file analysis. But honestly, for overall power meter usage, you'll spend a lot of time/effort doing for yourself what the Cyclingpeaks folks have already done.

Yeah I know. That's what I am currently doing but I was hoping there was some solution out there that would allow me to just click one icon as opposed to going through the steps in poweragent.

It's not so much CAN as NEED. But... this coming from someone who doesn't use the PMC in Cyclingpeaks. I use one in Excel with a lot more adjustability.

Oh yeah, well do you have TSS, IF, TSB, ATL and CTL in one colorful customizable chart?

:D

ElJamoquio

No. I calculate NP, and obviously could quite easily have TSS if I wanted it. It is a colorful customizable chart. I don't know what IF, TSB, ATL, and CTL are, but if I wanted to, and knew what they were, I could add them.

How do you manually calculate NP? If it's not too terrible to explain.

IF, TSB, ATL and CTL are almost all calculated off the information required for TSS or TSS itself. If you can get TSS, you can pretty much do it all. Training with Power and the website has almost all the equations and methods. Pretty interesting to read through.


How do you manually calculate NP? If it's not too terrible to explain.It is a 30 second rolling average of the power data in watts, if I understand correctly.

Lately, I've decided that I'm not riding with a PM during winter base. Screw it. I'm giving myself a break from the calibration checks and graph analyzing and all the other cruft that comes with measureing power. I re-installed my CatEye double-wireless. That's all the computer I need for now.

I'd post the file, but I zipped it, and it was still 1.1 MB.

Column R.

Watts is actually in D, and NP is in column P. I was using A, B, etc as examples.

I still don't see the 30 second rolling average in your example. It looks like you take raw power, raise it to the 4th power, average, and take the 4th root.

:D

Do you have a rolling 7 day average TSS? (not weighted, ala ATL)
Rolling 28 day TSS?
CTL Ramp rate?
Does Cyclingpeaks allow a scale for your weight that doesn't start at 0? (like I ever plan to weigh less than 160?)
Calorie intake?
Perceived Exertion to TSB comparison?
How about an entry for PE at all?

Cyclingpeaks is way inferior in graphing capability to anything Excel can put up against it. I use cyclingpeaks to examine actual power files, comparing sections based on both average and normalized power. I use it to do all the power file math for me (to get Normalized Power/IF/TSS). I use it to examine and compare heart rate/power output information when I feel like it - but almost exclusively for single rides at a time. For the PMC and long term training stress (as well as diet management in my case), I've found Excel to be a far superior tool - especially when it comes to planning workouts based on desired TSS.

Which is why you should offer up your spreadsheet so we can eyeball it :)

Seriously, I find gaps in CP's abilities. I used to write the odd Excel program but have gotten lazy. Love to see what you've come up with.

You're not using Excel. Excel should be used for everything.

You can do a lot in Excel if you are mathematically inclined and decent with computers. Should you program training software yourself instead of buying CP? Probably not.

Personally I enjoy playing around with my data in Excel. Different strokes for different folks.

I am willing to wager my excel sheet is one of the most complicated on the board and can do stuff that CP can't. It's only 6,295KB.
