Running Power Estimator

Description

A running power estimator using pace and gradient based on Manetti et. al. (https://www.ncbi.nlm.nih.gov/pubmed/12183501). The running power is saved to FIT. Note that GPS-calculated elevation may have major distortion and affecting Run Power results.</p><p></p><p>Example: Running 95 minutes and burning 1400cal. 1400 * 4184 / (90 * 60) gives an average of 1084.7 Watt .</p><p></p><p>Settings:</p><p></p>

Hi, what is 4184, where does it come from

Conversion factor of kcal to J is 4184.

It’s time to correct it :-) “ Example: Running 95 minutes and burning 1400cal. 1400 * 4184 / (90 * 60) gives an average of 1084.7 Watt .” Instead of 90 it should be 95. To be honest I spotted it when I first downloaded the app years ago, but was curious whether any other users highlights it or not. Shame on them for not doing that, and shame on me for the test.

I don't exacly understand, when i'm running i should set 24% of efficency? Or 100%?

Developer Reply
January 12, 2021, tmatthey71

100% means what you totally burn during running and 24% is typically what you actually deliver, moving your body.

Adjust the efficiency factor.

I not understand that number i have in the AVERAGING TIME OF PACE and DISTANCE FOR GRADIENT. What number should for me? thanks

Developer Reply
November 4, 2020, tmatthey71

AVERAGING TIME OF PACE : the time interval the pace is average over. Longer interval more smooth pace and short more respossive, but more unstable due to measurements fluctuating. DISTANCE FOR GRADIENT : The distance the calculate the gradient. gradient = distance / elevation difference

Sadly the data field shows me only a timer on my FR945. Additionally there is no data recorded regarding running power

Strange, using FR935 works.

1st go at the app. Muz say it looks good! I can see the power data on garmin connect but does not show up on Strava. Would be great if can be displayed on Strava!

Developer Reply
November 4, 2020, tmatthey71

Thx! I do not think that Strava supports power for running and for sure not some other custom field.

Great app and simple way to have run power estimation without other device. After reading the Manetti et. al article an prorun.nl review I wonder if possible to have excel/Google sheet to calculate run power estimations for past workouts? Thanks.

Developer Reply
July 28, 2020, tmatthey71

Thx! This should be possible with Excel. You'll need to extract distance, time, (pace or speed,) and elevation into Excel. The changeling part is to find current velocity and gradient to be smooth enough, but still capturing the details. For the gradient you can use Excel linear regression and for velocity a window average over 10-30s. Doing this as post process you can get more accurate velocity and gradient values, since you look ahead, which my data field cannot. Then use Minetti.

Excellent ! Thanks for this app ! Where is possible to see avg power by circuit in Garmin connect... ? Impossible for me to find that.

Developer Reply
July 28, 2020, tmatthey71

Thx! The app should show the average per lap. I know there are some issues on IOS, but I have never figured out why,

Aplikacja super. Mam tylko pytanie odnośnie bardzo dużych różnic w wskazaniach mocy w porównaniu do Garmin Runnig Power. Tam są zdecydowanie większe wskazania mocy. Nie wiem teraz która aplikacja daje rzetelniejszy odczyt..

Great idea. Can you list the defaults in the description on connectiq, I'm not sure if I changed them or not from having it previously installed. Also, possible to have a treadmill mode? Maybe allow user to enter treadmill grade option or default to 1%.

Developer Reply
May 17, 2020, tmatthey71

Good point. I'll take that for the next update if possible.

Hey! Thanks! This is really good. I wanted to have a look at the power estimation algorithm but the Bitbucket source code repository seems to be private. Is that intentional?

Developer Reply

Thx! It is a private repo ;-)

Really great data field. I don’t have a Stryd, but I’ve always wanted to be able to train with power. This seems like a good way to do that without spending hundreds of dollars on power meters. As with some of the other reviews, I would only ask for a couple of extra features: 1) Average Power 2) Some mechanism for setting a target power range 3) The ability to export the power data to partner apps Again, this is an AWESOME data field. I’d high recommend it!

Developer Reply
May 4, 2020, tmatthey71

Thx! You should see the power average in GarminConnect and it should also give the average power for each lab.

Still love it. 2 questions: A) if I use a footpod speed/pace data to be averaged come from there, right? B) Is grade calculated by the data field from elevation change and distance change or does the data field directly take the grade calculated by the watch?

Developer Reply
April 4, 2020, tmatthey71

Thx! 1) I assume reading pace comes from the best source. 2) Gradient is always calculated elevation / distance. I have not investigate if and how good evtl build-in gradient is .

Great App. One thing would be usefull: When you export the fit file the epower could be exported to. At the present moment, when you export the activity, this data is not attached.

Hello! Downloaded and did one run with it :) Do I need to adjust the 'Efficiency' from 24% to 100% for running or can I keep the default? Ref: 'Efficiency: Setting to 20-24% gives you approximately similar power out as for cycling, where as 100% is the energy you burn during running.'

Developer Reply
February 7, 2020, tmatthey71

Thx! 24% is to get the effective power (like you would get from Stryd) and 100% is the power you burn.

Works very well. Average Power displayed as a single datafield or combined with real power would be great.
