Hi,
For winter i use a trainer that provide power .
But i dont have a power meter on my bike for outdoor season.
Will intervals.icu still provide the same data analysis without power ? Is threre a way to make intervals work without power but only with heartrate ? What will be the drawbacks ?
Intervals will automatically use HR data when power is not available. It will provide a TSS for your ride and will provide some ride based analytics based on HR including time in zone etc.
Here is an example of a outside ride of mine from yesterday using HR only. This ride contributes towards TSS, overall time in zone, fitness and any other parts of Intervals that uses HR metrics where possible.
Thanks for the infor .
And how about your fitness graph , does it impacts ?
I can answer that the other way around. I had used intervals.icu for over a year just with a HR monitor and found it very useful with that alone - the fitness / fatigue / form curves work without it. I recently splurged on a power meter and of course I get a whole lot of additional data, but I would by no means say that intervals.icu is useful only if you have a power meter. There is one particular chart, the chronic intensity load (CIL), which was impacted in my case: it was rather flat before I had a power meter, but has since gone up rather significantly, while my fitness curve stayed flat. I am sure David can explain why that is, but I guess this just means that CIL is based on power more so than on HR, but I have not looked into the details.
Yes your fitness chart is impacted. For example I went from 82 to 84 CTL (fitness) after my ride yesterday.
Intervals works very well without power
Probably the intensity of your rides is being more accurately reported by the power meter. Thats what goes into the CIL calc.
One thing I’ve noticed recently: short (< 30 minutes) very easy commute rides with HR but no power have given me a 0 or -1 load score (which I adjusted manually).
Hmm I see you are using “time in zones” for bike HR load. I need to fix that. You could change to HRSS.
Where can i get the CIL graph ?
On the /fitness page. Click “Options” and “Add chart” and choose “Custom”. The click “Add plot” and choose “CIL” from the list:
Thanks,
I notice the graph of the CIL follow exactly the fitness graph
They rise and lower at the same rate.
Is that normal ?
Also what is the purpose of CIL and how can I use it ?
Thanks
Some useful info here: https://www.trainingpeaks.com/blog/chronic-intensity-load-a-new-measure-of-training-load-based-on-intensity-factor/
Chronic Intensity Load (CIL) is not designed as a replacement for CTL, but simply a useful addition. Athletes and coaches should monitor duration of training carefully, but CIL gives an indicator of how the quality of training is progressing through the season.
Thanks !
So basically, if I train for the same hours over weeks but my CIL raise sharply it means I train efficiently since I increase my intensity ?
