The good news is that I've just done the power comparison again - and the 2T gave slightly higher power readings than my Powertap pedals. People say the NEO is mean with watts so I have been worried I'd be losing out.

So this is why people love the Neo @<Tommy> ?

Seriously though @Norry1 this seems like a bit of an odd result to me? We'd expect to see a slightly higher output at the pedals than at the turbo due to drive train losses?? Not sure what typical losses are on the drive train but I wouldn't be surprised if it was 5-10W?

Heart rate is a very personal thing, and can be influenced by all sorts of factors. If you are worried speak to your GP, don't rely on anything we say!

I also have a high heart rate - peak of 198bpm and average of 186bpm last night (https://zwiftpower.com/profile.php?z=221557)

Anything that anyone tells you about heart rate can only ever be a guide, it is a very individual thing. Having said that, the younger you are then the higher your maximum and average heart rate tends to be during exercise. How old are you? I'm 32 and have similar figures to you.

A lot of people will say things like "the fitter you are, the lower your heart rate will be" - in my personal experience that is not true (but will vary between individuals). If I am well trained I just put out more power for the same heart rate. Fatigue and illness do lower my HR though - in either case I struggle to get the heart rate up, despite power usually only slightly lower

Honestly, heart rate is such a personal thing that it doesn't really matter what anyone elses experiences are - yours are very likely to be different. You probably just need to figure out what is normal for you and look out for changes to that.

Also 32

I've got a phone appointment with the GP in a week and a half!

I think mine has always been pretty high - a treadmill in a gym shut off once when I held on to the sensors, lol.

For any of you who have looked at your efforts from last night on Strava, you'll see that there have been a few more segments added by ZwiftInsider for non-official climbs such as Otley Road, so the list of segments now doesn't look quite so empty (but still a lot tidier than it was).

As these are newly created segments, Strava doesn't automatically go back and track previous performances on this course like they do for outdoor segments, so you can't see whether these were your fastest times or not. However, you can force Strava to do this - it does require a bit of work on your part and it's easier to do for maps where you haven't ridden as much (so for me, anything but Watopia and London!), but it's still do-able.

Simply find all your previous rides on the course you're interested in (easiest to do by looking up your previous results on a segment you know has always been there and still exists, such as the KOM or Sprint), go into each of them in turn and click on the Edit (pencil) button. Now change the Sport from 'Virtual Ride' to just 'Ride' and then save. Strava should figure out it's not a normal Ride and change it back to Virtual Ride (if it doesn't, you can always edit it yourself again), but that is enough to force Strava to re-check what segments you've matched.

I gave my drivetrain a proper clean before installing it on the NEO and also put a new cassette on - so I think losses should only be around 1%. But even the best Power meters only claim +/- 1% so this is easily within the margin of error. I agree though that on average you'd expect a slightly lower reading from the NEO than pedals - so I'm pleased it isn't looking that way at the minute. Also nice to get some reassurance that the source I have been using is in the right ballpark.

As with most of health related things it's best off to ask a doctor rather than an internet forum, unless the internet forum has a doctor on or is for doctors. Any doctors??

Seriously, ask your doctor. I'm sure it's fine but if you are worried get it checked out.

It could be you just handle suffering better than us mere mortals

@BurningLegs has put it very well. There's quite a lot of natural genetic variability about but age and fitness play a role. People used to say 220-your age. That isn't great but it gives you an idea how younger people will have a higher max HR.

Going to see your gp is never a bad idea, particularly if there is any family history of any heart conditions. Don't be too nervous though, you see some YouTubers hitting 200bpm plus regularly.

I have noticed on Zwift power that last 3 group rides what i have done only w/kg, avg power and avg heart rate is appeared but other values are missing. Any thought what can cause missing data?. Many other riders data is showed up. A bug perhaps?.

Well I enjoyed that race even if I wasn't at the pointy end.

Also enjoyed the NEO2T. I think it helped feeling the resistance kick in on upslopes and then fade on downs. I think with the dumb turbo I have been slow to react on small inclines where the pack will increase their power but I don't. Likewise I think I gained a bit more respite on the -1, -2% parts where I naturally backed it down a bit whereas I probaby wouldn't have done before.

The good news is that I've just done the power comparison again - and the 2T gave slightly higher power readings than my Powertap pedals. People say the NEO is mean with watts so I have been worried I'd be losing out.

Great Zwiftpower tool

I can't find the graph. Where do I look Martin?

I enjoyed last night's race as well. My first outing in ZRL2 as a late replacement.

I was very happy with how I rode, even though I finished 86th out of 94! I could see you 2 seconds ahead of me as we started the first climb of Otley Road, but I just couldn't close the gap to the main group.

Same issue as ever for me, as I just didn't put out enough power to stay with the group at the start, but after that I felt strong the whole way round. I was 25s after @IrishAl and 1m 43s behind you and @Alongo. Pretty happy with that.

I really only missed the lead group by a small margin. I've been starting better and short term power has been improving so I was encouraged by last night, rather than frustrated by it.

I was in the points coming over the 2nd KoM in about 79th place, but I'd put in a big effort on the KoM and just couldn't hold it to the line.

Our team did really well as we took 1st and 2nd place and quite a few KoM and sprint points.

Looked like the best night of the league for CC#23 as well. Hopefully you guys can keep it up and pull away from the bottom now.

You can only see your own ... on ZP, in your own profile you will see an 'analysis' menu option on the bar. Click that and you can select your FIT file to display the data.

Probably a good tool if you have 2 power sources, but as I only have the one it only shows what I can see in Strava

Got it! Thanks!!

Select Martin from the team list, after that up on a screen is a grey bar where is a analysis function, there it is.

Paul has found a way to see other riders power data in ZP .... click on their name to see a list of their recent rides. Scroll to the far right of the ride data and click the last icon. This will open the power graph for that ride.

Below I have shown the 2 guys who looked to be cheating, plus my graph as comparison. To me this looks pretty conclusive. What do others think?

This is one of the guys who looked to be saw-toothing last night:

This is the other guy :

Hard to say much except Carl is coasting more than two other guys but nothing unusual. Lower guys graphic looks bit weird, different pedaling than guy above?. That was my first impression without any facts.

They're definitely using the saw-tooth ..... big power on, stop pedalling. big power on etc etc. It's a 'feature' in some trainers and considered cheating.

I'm really not coasting ... not with a heart rate at 187 anyway

Yes that's a pretty clear difference between your "normal" power curve and the other two - mine looks very much like yours by the way!
For the second guy - the even more blatant one - I have his Strava analysis too which includes cadence, so you can really see what's going on:

Whorty:

"Other guy"

Look at the cadence and power of "other guy". And below is a random cropped section so you can see it in close up. The cadence is around 60 at the bottom of each trough and around 100 at each peak, and the powergoes from around 60-70 watts to around 500 at each peak:

All solid advice here suggesting you speak to your gp about HR.
I am the only male in my extended Irish family who doesn’t have angina. Some have quite worrying heart issues. Also my sister suffers from tachycardia and has to be rushed to hospital far too often to have her heart effectively reset. So I try to be careful about things and have read a lot around the impact of high intensity (for me 😁) exercise on heart health.
HR variability and recovery seem to be the key indicators. My resting HR of 35-45 often throws nurses who think they are using faulty HR equipment. Or I am Ill. I have hit 184 in a race. Lots of variation depending on fatigue or illness. What I always watch for is how quickly my HR falls. One of the benefits of a training plan is that you do get to see this in a way you may not do so if you just race. Of course the TP has to test your limits. So, I know roughly how long I take to recover.
This is a good article and suggests there is good reason to be concerned about the impact of endurance training etc on heart health. There was also a cracking gcn by Si dealing with heart health. The reality is we are all doing ourselves a lot of good physically and mentally riding and racing and pushing our bodies and that it far outweighs any risks but good to be mindful.
