Showing laps in activities

I don’t quite get the resistance to implement laps and similar. Seems a pretty straighforward and simple feature to implement.
I get @xertedbrain take “Roads? Where we going we don’t need roads…”, but some people do, or at least think they do.

But wouldn’t a lap function allow you to do this? Say I am doing hill reps,it would be good to see what my finishing MPA is on each of those reps?

You can see (or mouse over) these on the chart directly. If you are looking to have a table with start/end times and start/end MPA with average power, for example, where you can click on each lap and have it highlighted on the map and in your data, that would be great, but it’s a heck of lot of effort to implement. (Truth be known, I’d like to have this myself). But outside of basic curiosity, it would be great to understand how this information will inform any future training or performance. Just because it can be shown and just because it would be interesting to see, doesn’t necessarily make it something that is valuable and actionable.


Yes but if you had a simple lap function at the end of each section of a workout then at least you would be able to see interval average numbers in Strava.

My point was about performing intervals whilst on a 2,3 or 4 hr ride. It’s tricky to isolate the efforts amongst all the other data from the ride. Or for example locating a regularly ridden segment and examining the pacing via MPA once back it’s hard to find in a 4 hour ride file, whereas locating a lap would be simple.

When I do 10 hill repeats, yeah I want to see the avg watts for each effort.


come on, people! everytime I come to this forum and read some suggestion from the community, the answers by the xert side are always careless. nobody knows what they want, know nothing about training and know nothing about navigate through this engineer-like-obtuse interface… and it’s all our fault.

the lap is not just about avg something, it’s a really simple omni-present function that helps like nothing else to navigate through the stream of data from the ride.

it’s a bookmark feature for navigation.

there’s nothing better yet. period.

if anyone is doing dozen hill reps, races, 5 hour rides with lots of efforts and wants to mark a specific effort anywhere, of any long, for whatever reason, that’s the tool.

it’s just fool to keep selecting, zooming in, and in again, and again and then out to reach a time period.

it’s like trying to reach out part of a book to review, remember, study and have no resource to mark it in plain XXI century.

outside of taking a quick look on mpa, I never analyse my rides on xert because is a pain in the ass. a big waste of time, like trying to pin ants on the ground.


Thanks Jonas.

The people that we talk to that come to Xert without any preconceptions, looking a laps and intervals never enters their mind. Breakthroughs and fitness signature changes provide everything they need to understand what’s happening. It appears to be more of a remnant of how things have been done in the past when “breakthroughs” (i.e. improvements in performance) only ever occurred in intervals that you needed to review to see. How these performances related to training is something you had to try and piece together yourself. Understanding how intervals were influenced by different systems (low, high and peak) was something only the best of the best coaches could ever infer from your intervals and only when they are executed with consistency (which coaches demanded!!). Hence, marking intervals helped identify both the intensities and the consistency so that you could compare and then evaluate how your fitness might be improving. With Xert, all this goes away. Everything is black and white without any intervals needed. The system determines what you can do ride-by-ride rather than what you/your coach can infer from your intervals. All this analysis becomes obsolete.

I would love to understand how seeing intervals/laps lends additional value to understanding your fitness that Xert’s methods don’t already make obsolete. I think there are some good applications of them but would like to hear what the community thinks first.

Btw, it’s no small effort to do this so would really like to know how much additional value they can provide the community. Keep in mind, that reviewing laps/intervals is something you can do on other systems that are free. If our resources were free and unlimited, it would be nice feature. But as it stands, it would appear to be a big replication of effort for us and would tie up resources to do this without clear understanding of how much real value it would provide our user community at large.

Feel free to start a debate on this. It’s an interesting one. Open to new ideas.

hey @xertedbrain,

well, i’ve just said what i think. if you guys think of xert as just the tool for us to check when a breakthrought happen or not. it’s done.

apart from it, the activities, primarily the outdoor ones, are messy long files, with hours of endurance and peaks of high energy efforts. everybody, anyone uses a platform like xert, strava, etc to go through them like to scrutinize it and, for that, we need tools to navigate them. navigate the stream zooming in and out, trying to pinch several pieces, doesn’t help. it’s lame.

in front of all the engineering that’s xert, there’s the interface. if it doesn’t help, what’s behind become useless, because people cannot access it. don’t you like the easy quick access, multi ways and shortcuts your phone has to access the same things fast and clutter free? everybody does. because is useful.

what’s being asked is not about fitness, you are already delivering that, is about usability, accessibility.

it’s not a waste, it’s not aesthetics. in the end, if xert doesn’t want to do it, for now that’s fine. in my case i use strava for that. if it’s not an activity that has some kind of BT effort and i just want to know about the ones i did when in front of the last group ride and relate to how that feel (which is the majority kind)… they do a better job. you guys keep being just the analysing thing that i plug with the place i can get around more easily. just come here once in a while to check weekly strains, BTs and export some workouts.

and it’s ok! there are all kinds of “engines” in all tech industry that lives like that successfully.

usually someone will come and make the sense from it for the majority, like the intervals online service somebody posted. usually it’s the place where the thing itself escalates… just like happened with smartphones.

and that’s all i have to give about laps.

Potentially where you want to analyse efforts that are below TP and so don’t draw down MPA i.e. endurance rides, which are 80% plus of what many do. For me, MPA analysis is only relevant for a fraction of my rides.

Can be useful to compare power vs HR for dedicated steady intervals throughout a ride (climbs or long uninterrupted stretches)… identify drift (how that looks for an interval early vs late in a ride)… identify improvements in efficiency or accumulation of fatigue over time (even if there are many factors affecting HR day to day) etc. There’s a huge amount of data and potential insight from endurance efforts which it feels like Xert ignores (other than including in training load) due to the exclusive focus on MPA.

To be fair, I think that’s not solved by adding laps alone though. E.g. ideally you’d have some kind of power vs HR (or HR reserve or more sophisticated) metric as well. The lap just helps the visualization and drilldown, and may make it easier to compare. I’d prioritize the HR insights over laps.


Again, anecdotal example of where this would be useful for future training improvements if that’s what you need Armando.

I go back to my initial reason for requesting.

I have a 10-12 min climb I use sometimes to gain some real world long climbing before I head to the alps (albeit not recently…). I ride out for and hour 15mins, ride it tempo (or thereabouts) 5,10 maybe15 times then ride an hour 15 back.

I would like to easily isolate each of these climbs and their impact on my MPA to maybe see if my effort could be increased next time or adversely to see whether I hadn’t got my calculations correct and should ease off to try to achieve the goals I set before I start the ride.

Same could be said for intervals out anywhere on a road ride?

I can find these laps easily in Garmin, Strava etc as they correspond to me pressing the lap function on my head unit. Unfortunately these platforms don’t tell me the metrics that we pay Xert for.

Are you able to provide a visual example? If you use the MPA datafield on your Garmin, you’ll be able to see MPA data in Garmin Connect so perhaps use that to explain together with the lap indicators.

Just curious to hear what you would find more helpful for learning or understanding Xert. We’ve made efforts for users who are genuinely curious and interested to learn more.

Unfortunately, human physiology is quite complex, so creating a tool to help understand it isn’t exactly an easy task.

I can understand the well made arguments for adding interval information. However there are tools that do that already and I doubt that there are many Xert users who do not use an additional product in conjunction with Xert.

A few weeks ago I sent an email to Support and posted in this forum and facebook that the calculation of the avg interval power by Xert Player was wrong. And still it is. I do not understand why the problem is not solved yet. I sent a second email and nothing. The problem is that the software takes 0 watts as the first value of every interval to make the average, which seems easy to fix. I recognize the high value of MPA analysis and I like it very much but monitoring the avg interval power is very useful to me. I do not use ERG mode and adjust manually the resistance as riding outside.

I don’t compete but I’m all for something that can boost your performance or help you climb faster. :smiley:
Please explain how comparing laps/intervals will lead to positive changes in your performance and fitness level.
Other than “handy”, “interesting”, “cool to see” or “potential insight”, what are some real world examples with actionable benefits?

Lap analysis sounds more useful when you actually ride a closed course consisting of X laps where you tackle each lap differently and compare the results. I suppose that could apply to hill repeats such as “lap 3” was faster than “lap 1” possibly due to cadence change or MPA drawdown difference. However, there could be other factors not necessarily captured in the data such as wind change, temperature drop, traffic interference, flatulence, etc.

As far as analysis of long outdoor rides, I don’t understand what practical benefit you could achieve through lap/interval analysis. There are too many variables, plus what would it prove and how would the results affect future training?

Assuming there is some value to it, implementation could consist of displaying a lap analysis button for those activities that include lap markers in the data. When you tap that button a special chart/table is displayed that magically makes you go faster next time. :wink:

Actually you can say the same about MPA, or XSS or TL or other metrics - none make you faster on their own; training does.

Intervals are just a convenient way to make analysis and comparison easier - within a ride or between rides.

For base rides (80 to 90% of rides) it’s about power vs HR… within a ride laps can help identify drift (ideally you compare two similar efforts, to avoid the other variables you mention… eg power vs Hr for the last 5 minutes of a steady 8 min interval, early vs late in a ride), or over time similar intervals can be compared to show changes in efficiency. These indicate quality of aerobic base, which can inform training focus and even intensity of endurance rides. That analysis could be done manually, but it’s cumbersome in the existing Xert set up, so I go elsewhere for those insights.

So I also agree with @johnnybike there are other platforms - though not all are free, and I suspect many would appreciate a way to save some money by having a one-stop shop (or be happy paying the same overall to a single company for that convenience = more money for Xert or whoever does it).

(Also appreciate Xert’s resources are not unlimited)
