davidtinker Posted June 19, 2019 Share Below is my data from a hillclimb event a month ago, not even 4 minutes but super hard... Please mail me links to those activities and I will take a look (this is new stuff, could be buggy or need tuning). Probably (at least according to the power curves in Intervals.icu) your FTP is a bit low. If you don't want to change it you can increase the spike detection threshold for the ride and in settings for future rides. Link to comment Share on other sites More sharing options...
davidtinker Posted June 19, 2019 Share I think I am going to have to dial this back a bit and bump the default power spike threshold up from 8% over your curve to 20% or so. Lots of people have FTPs set very low, easily 8% or more under what Intervals.icu thinks it should be. People with dodgy power meters and correctly set FTP may need to tweak it down to eliminate enough of the spikes. HdB 1 Link to comment Share on other sites More sharing options...

People with dodgy power meters and correctly set FTP may need to tweak it down to eliminate enough of the spikes.Small issue - I've updated an activity with a higher threshold, but when I close the intervals.icu tab, and reopen, the Power graph for the activity looks like it is still based on the default 8%. But the value at the bottom shows the updated value, for example 20%.If I edit it again, and just select OK without changing the number, the graph updates correctly Edited June 19, 2019 by HdB Link to comment Share on other sites More sharing options...
madmarc Posted June 20, 2019 Share I have been doing some work looking into the relationship between power and heartrate. Intervals.icu now includes a power vs HR chart for rides with power and heartrate. Screen Shot 2019-05-04 at 21.02.31.png You can use the de-coupling % on an endurance ride to figure out if you have done enough aerobic riding. But be careful because this is heavily influenced by hydration levels, temperature, time of day etc.. I am going to be adding "Power @150 bpm" as a line on the fitness chart soon. How do you get the decoupling % to reflect, is this a manual entry somewhere ? On my graph it only shows power at 150 bpm and model fit. I also don't see the 2 lines for 1st half of ride and 2nd half of ride Link to comment Share on other sites More sharing options...
Jaco-fiets Posted June 20, 2019 Share David does your calendar always sync with strava? What if I want to delete a ride from strava but would like to keep it on your calendar? Link to comment Share on other sites More sharing options...

The ides is that is more something to look at on longer rides. RossW 1 Link to comment Share on other sites More sharing options...
davidtinker Posted June 20, 2019 Share David does your calendar always sync with strava? What if I want to delete a ride from strava but would like to keep it on your calendar? It will disappear from the calendar. You could just mark it private in Strava instead? As far as I know I am required to delete data obtained from the Strava API when a user does so.

davidtinker Posted June 22, 2019 Share You can now see normalised watts and training load for each interval. Click the "Fields" button under the ride timeline chart to add them. These are only visible for newly analysed rides and rides you re-analyse by editing your FTP (you don't have to change it, just click it to edit and choose ok).

Andrew_Smith Posted June 22, 2019 Share Apologies if this is a dumb question but how does one work out your W'J? Edited June 22, 2019 by Andrew_Smith Link to comment Share on other sites More sharing options...
davidtinker Posted June 22, 2019 Share Apologies if this is a dumb question but how does one work out your W'J? You can get it from the /power page, its listed at the bottom of the chart for each power curve plotted. It represents how much work you can do above your critical power / FTP before blowing up. You can see how it works by adding the W'bal chart to the ride timeline view. When you are riding below FTP then it recovers. The model isn't perfect as it doesn't consider fatigue at all.

davidtinker Posted June 23, 2019 Share Intervals.icu now has power profiling on the /power page (thanks to shaper for the suggestion). What kind of rider are you? I still need to do a bit of work on this. Distinguish between climber and TT guy? Under 70kg = climber? Frosty, HdB, MDJ and 4 others 7 Link to comment Share on other sites More sharing options...
Vetplant Posted June 23, 2019 Share Uhm, I think there is only one feature that you haven't incorporated yet and that is the tool to decode the true meaning behind the words of the woman in your life... Seriously though, this is covering allot of very cool features already, well done. davidtinker 1 Link to comment Share on other sites More sharing options...
