Plot charts at interval level?

[romainlacombe]

Hi everyone, new user and first time poster so apologies if I’ve overlooked something basic — and a huge thank you for this fantastic tool!!!

I’d like to track an estimate of my running AeT pace over time to see if my base training delivers long term changes to aerobic pace.

For that purpose I’d love to plot a chart of pace vs. HR for each interval of all activities I’m filtering for (here, say road running only to avoid elevation bias from trail runs).

I would then add HRZ bands to track cut-off pace at the top of HRZ2 i.e. AeT (in the Uphill Athlete zones model). Ideally I’d fit a trend to avoid noise, and allow comparisons between specific time periods (e.g this season vs last).

Is that possible, and if so where can I read docs to write the corresponding script? Thanks a ton again!

You could start by calculating pace/HR (or something similar, I only do cycling) for each interval and then maybe combine that into one number for the activity. It looks like some people have already done some of this work (under the activity timeline chart do Fields → Custom and search):

Then you could plot that over time on the /fitness and /compare pages.

Here is an overview of how you can extend Intervals.icu:

Extending Intervals.icu

This post pulls together all the ways you can extend Intervals.icu. Some require a little Javascript knowledge and others just picking a value from a drop down. Intervals.icu also has an API.

Ooh that’s fantastic, thanks so much for the answer! I will explore and report if I have questions.

A first one: does this mean I cannot pass say an array of values from an activity (e.g. {interval1: metric_a, metric_b; interval2: metric_a, metric_b; etc.}), so that I could correlate a and b on an interval basis across activities?

Thanks again for your help and answer, very helpful!
