Wahoo Training Metrics FAQ

Full frontal should set your target RPM but you can change it in the Wahoo App.

Oké, ik ga er naar op zoek

Does non-estimated DTL depend on a recent FF? I last did one towards the end of Feb (have done a HM since) and am getting estimates.

If you did a Full Frontal recently, your DTL should not be an estimate if you rode with power AND cadence. If you did a ride without power and cadence, you will get an estimate regardless of your 4DP values.

Hi @Helga . I was on my Kickr Bike Shift, so definitely had both. I did the get the dodgy results message at the end though as my AC is so laughably low compared to everything else (or, rather, my ability to do a decent job of this section of the assessment).

After a rather couchlandrian phase I’m back in sufferlandria since some weeks now. I’m quite obsessed with the metrics. It’s so motivating to see the curves rise and they help to choose my workouts (I don’t like fixed plans).

Is it possible to achieve more than +0.2 on the fitness score for a day?

What’s the maximum estimated recovery per day you’ve seen?

I’m with you, I also always look at it and use it to guide workout selection as well.

Flipping back through my history, I’ve seen a day change of +0.5. Estimated recovery is harder to track since you can’t see it in the history charts.

It’s also important when looking at these to remember that the fitness lags more than traditional TSS, so the day gains should be less. I did a 251DTL ride yesterday but that will be smoothed out in fitness gains over a few days rather than a sharp increase in the TSS fitness I get from Strava or intervals.icu.

Does anyone else find that the metrics show that a workout isn’t hitting the system it’s supposed to. I did rue the day thus morning, which is supposed to be a MAP workout, yet the metrics don’t show any DTL from MAP based efforts and over all give quite a low DTL.

This is today’s:

This is last time:

Why the difference, and neither hitting MAP?

@Helga, any info on this you can share?

I’ve been finding that and reported it as well. My guess is twofold:

  1. There’s some time filter the effort has to hit in the analysis to get qualified as MAP, like a minimum 30 or 40 seconds. Whatever it is it’s too long to capture most of these intervals.

  2. If you run over the MAP range for a second, then all of a sudden it counts as AC. I’ll frequently be riding up a hill outside right in my MAP range, jump up to the AC range for 3ish seconds when the grade changes, and then the whole hill is AC when I go look at the analysis.

That said with your workout, maybe it’s cadence? That can change the amounts of AC and NM surprisingly much. Also, did you do them in Level Mode?

Yeh, I find the same. That said I was getting a lot of MAP efforts registering as AC but suspected it may be due to a relative weakness with AC, so as soon as I went over MAP I was relying on AC. Since improving my AC relative to my MAP I am not getting that as much.

I was in ERG mode and pretty much bang on the cadence targets today. Most of the workout has gone down as ‘moderate effort,’ but it didn’t feel moderate!

Yeah it’s not great.

Honestly I’ve resolved myself to the fact that MAP is going to be woefully underestimated, but hopefully uniformly underestimated, and use it as a long term trend.

Unfortunately I had a period last fall where I kept repeating 9 hammers and Joyride to bump my VO2max (it worked!) but my metrics are forever skewed since those have long enough efforts to trigger MAP.

I also find it hugely under scores the DTL for outdoor efforts and I’m using a power meter. I’ve been going hard recently yet the metrics say I’m fairly fresh and I’m struggling to keep the metrics in building phase. My guess is that it is due to the naturally spiky nature of power outdoor as the road fluctuates.

I can do a 25 mile TT where I turned myself inside out for an hour, and the metrics say I’ve done an easy ride. I think it is because I am flitting around threshold as the road goes up and down, rather than holding a steady power like when indoors, so I never hit that time stamp for it to count as a sustained effort.

The result is the metrics currently say I’m not very fatigued and have lost fitness, but I know that isn’t true as I feel tired, but have also seen progress (Strava segments and race times) when out on the bike and know I am going better than a month ago.

I’ve just signed up for intervals.icu and backloaded the last year of data into thst. At a quick glance what it is saying seems closer to how I currently feel, fitness and fatigue wise.

I find it’s better than the Wahoo analytics if you’re doing a lot of non-cycling activities.

Of course better than Strava.

I don’t subscribe to Strava, don’t really understand what the paid features give you that isn’t available elsewhere.

I will be doing a lot of running later in the year so will use intervals for that. I don’t really run much, done a couple of half marathons a long time ago and do the odd 5 -10km run, but had an itch to do a marathon but being a Sufferlandria rather then scratch that itch, I’m going to take a rusty cheese grater to it, as I have signed up for the Brecon Mountain Marathon. I decided I wanted a real challenge that would take significant suffering to finish and fancied getting out in the mountains, so before I could come to my senses I signed up and got my brother on board too.

I used to use Strava’s fitness/freshness during my last big cycling block but that was over a decade ago. I’m loving having this even more comprehensive view now I’ve picked the bike back up. It really gives that feel of progress.

I did the MAP 8*3 the other day and the results did skew quite a bit up into the AC, but AVDP a couple of days before was, as expected nearly all in the MAP zone (even though its not the AVDP I used to know that I could never finish - and I do buy the ‘its better to finish’ pitch…) . Whoever said the short period / going over the limit is probably right.

I still find it super useful that it’s more varied than just a flat FTP based view.
