About 2 years ago I saw a GoPro type video of a guy in a scratch local race. The cool thing was that the video had an overlay of the data from his power meter. ... Eh - we'll see. |
And in a related topic it looks like Chevy will be offering the data recording/playback with telemetry on the 2015 Stingray
http://online.wsj.com/news/articles/...DDLE_Video_Top so the thing looks like it has hit mainstream. They mention voice recording too so you will have to watch your language and I suspect the insurance companies will ask for the recording along with the claim. |
I am sure there is somewhere out there where i could get a bigger pool of people to help me with this- but since this is the only forum i frequent... ill start here.
i am having issues with the "Find Intervals" function on my SRM files.. other files with power data from 2 bikes with Stages meters collected with Garmin are not having issues.. i cant get any intervals to show.. anyone know what im doing wrong? |
adding a bit more info to this- hoping for some help while i search elsewhere on the web for the answer...
so my issue is only on SRM files from an Ergo- I can use the "find peak intervals" function the "find best intervals" function is not working both functions work properly on all my other files (all garmin/Stages) Thanks |
I've found that the Golden Cheetah developers to be really approachable. I ID'd a bug a couple of years ago and a developer from Germany worked with me via email to get it sorted out.

This means that you aren't registering any distance traveled. This may also be registering as time not elapsing either. Not sure. I know that when I home-trainer efforts on the track bike using the SRM, when I download the file into SRM software, I have to lower the threshold for it to accept data. The default is something like 5 minutes or something like that. Put it to 0. I'm writing from memory, sorry to be imprecise. |

OH! I think I know what might be happening.

Kind of off topic, but what is your erg setup? I am thinking of setting one up and would appreciate any information.

Have you considered mounting the SRM speed sensor to that wheel in order to get a complete data set (speed, cadence, and power) in the file?

Yeh- I've played around with it. Just need a spacer to get the sensor in position, and I need to go into the SRM software and program the wheel size to something Tiny.. That wheel spins at 75mph+ on a hard jump!

Thanks for posting this. Had just got back from Europe so didn't race that one, but this is my local indoor track I normally race Tuesday nights and on searching through his videos found one I'm in...
Was in a short lived two man break at the 9min mark but it unfortunately didn't stick. My mate Cam was up the track in the final laps so I soft pedaled when on the front but also in the end I should have moved up earlier as gaps opened and I was too far back; made up heaps of ground but only came in 5th. I'm in the red skinsuit and running a disc. The guy that won that race (Chris Hickey) is up here in Brisbane now. Are you going to Nationals in March? JMR |
Footage is at DISC JMR. Chris being up in Brisbane explains why I haven't seen him in a while...
I will be racing the Nationals - pursuit and scratch. You? |
Very nice! Do you just use the wheel for drag, or is there something I can't see that adds resistance?

the Double Drivetrain gets the wheel spinning at 2-3x normal speed. I've clocked it a near 100mph. The power curve is really realistic. The beat feeling resistance trainer I've ever used. |
Thanks. Wish I could afford the $2500 Predator wants for one. Heavy Sigh!

My knowledge and usage of power for training is pretty basic. For those who are deeper into it, are you able to see your torque values? I'm guessing that would be torque at the crank and not the hub, right? What kind of max torque values would a cat 2 sprinter expect to see?

Maybe look for Torque/Kg just like people look for Watts/Kg as a way to compare different riders. Here is a chart made by Andy Coggan where he generalizes W/Kg over different time periods (5sec, 1min, 5min, Functional Threshold) to describe different categories of riders: https://s3.amazonaws.com/cyclinganal...ower-table.png Take it with a grain of salt. That table is no different that comparing Squat numbers and trying to extrapolate Flying 200M times from it. |
Based on 1min power that chart puts me right in the middle of cat-5

Did it resolve your cat 5 power? :p

Does anyone here know how to make custom charts in Golden Cheetah?
I'd like to plot acceleration using speed data. Is this possible? |
