Powermeter data
Using a powermeter with my bike, I'd find valuable to get in the summary and interval section :
* VI (Variability index),
* EF (Efficiency factor),
* Pw/Hr,
* and IF (Intensity Factor).
This is what you want to analyse your workouts with power.
I'm a Training Peaks user and I gave a try to SportTracks. You made good work, and you are much less expensive ;). But for the moment, I need my power data with the information above. Keep going ! Cheers
Fans -
We’ve added a few new columns to the workout list for powermeter analysis. Click the “Customize” button on the workouts page to add the columns:
http://sporttracks.mobi/workouts
- nPower (Normalized Power)
- iFactor (Intensity Factor = NP as a percentage of FTP)
- Power Variability (VI = NP / Avg Power)
- Aerobic Efficiency ([NP | GAP] / Avg HR)
In the workout detail page we’ve added iFactor % to the total block display (at the workout top) for the nPower value. We’ve also added %max HR, as it’s a similar concept.
A few more enhancements related to powermeter analysis will be coming up in the actual workout detail page.

Please can you add time in power zone chart? For each ride and over a selectable date range in charts? I was shocked not find this when I recently switched to the 80/20 plan. I'm having to take a separate subscription to training peaks to get this and sports tracks might have to go ;-(

Hello,
See you still working on this?
I would like to See a critical power Graph over all of my Data an be able to compare a Single workout to this "best of me"....Is this possible?
Also i would like to have a Graph with my critical power Watt/kg changes over the Time. To See if i getting better.

I would especially like to see IF and NP. I know NP (ST = Level Power) is an option to toggle while viewing a workout, but I would like to see it as a field or column on the workout page. It gives me a better idea of how hard a given ride was, along with the IF.

Variability Index = Normalized Power / Average Power.
- There are probably better calculations for true variability we can introduce. Also applicable to runners for pace, vertical oscillation, ground contact time and cadence smoothness. A bit pointless to do an entire workout but definitely useful to add to segment analysis page. VI is optimized per athlete for a single course. So most useful doing the same course over and over (or using Trainer Road to simulate it). If you're out riding different courses - not much use.Efficiency Factor = Normalized Power / Average Heartrate.
- Another useful analysis for segments. Possibly useful on the analysis page, but conditions of different workouts can show great variation. Comparing same rides/runs only would make sense (same weather, training load fatigue, etc). Difficult to make training choices from this because of variability. Some argue pure power based analysis is enough.Pw/Hr = Efficiency Factor. Same as above.
Intensity Factor = Normalized Power / FTP. Mathematically the concept is similar to showing average heart rate as a percent of max (with some scaling). Useful and easy to calculate and show as a percentage of Normalized Power. Doesn't give the same detail as zone analysis but a nice high-level number.
