No that's what I'm saying, my real-time cadence from the PT is pretty stable. Only shows a high of 120-130 in races, which is about right for me.

I've gotten it to show 200+ by spinning a 39x21 (or so) down a 8% grade, and that's when I start to think it's numbers are a bit off. I doubt I can really pedal that fast..

What kind of IF would be believable for a hard 4 hour group ride?

I tested my FTP on Thursday and was practically cross-eyed and drooling by the end of the effort. I don't think I could go harder than I did in that test on the same course. But I did come away thinking that I could produce more power at the same level of perceived effort on a hill climb, rather than the flat course I used. Maybe Saturday's ride with the high intensity factor is evidence of that hypothesis.

I've had .85 for 3 hr rides with hills - I wasn't spent, but I wasn't looking to do another hour either.

Hey guys - I have a question.

I just started riding with my Quarq, and the other day did a FTP test, and then today, did a power profile test ( according to the book ), and came up with some unusual results, and was wondering if some of you that are more experienced could point me in the right direction.

The values I came up with are :

5sec - 1min - 5 min - FTP
16.09 - 6.41 - 4.44 - 3.54

Any idea why my 1min would fall within "untrained" where all my other numbres are in the upper levels of moderate? In the book, it mentions this scenario, and to be suspect with the numbers. Is this just something where I need to record more ride data and come back to it?

I just thought that by performing the power profile test today that it would've tested everything and given me reliable data? Maybe I need to re-test?

Thanks for any help!!

By definition you can't ride for an hour over your threshold, since threshold is the most you can do for one hour.

I'd use the best 1 hour from that segment for your threshold until you do a test, because it'll be even higher than that.

This is a good problem to have.

It wasn't 1 solid hour riding above threshold. More like lots of 5-10 minute stretches of riding above threshold that added up to over an hour of riding above threshold by the end of the 4 hour ride.

Anyone else have thoughts on how high IF would have to be for a 3-4 hour ride to conclude that FTP might be set wrong? It sounds like a few of you are skeptical of 0.93 for a 4 hour ride, so I should probably redo my FTP test (which I just did for the first time on Thursday).

I'm no expert, but --> How fresh were you when you tested your 1 minute power? You rely heavily on neuromuscal strength and anaerobic power for the really short efforts, so it is really important to be fresh to get an accrurate result. I'd just wait until after your next rest day or two and then re-test it.

Um, yeah, non-continuous time over threshold doesn't really "count". Especially if you have good anaerobic capacity, you can keep punching high efforts over and over with some recovery, but that doesn't mean you would be able to actually sustain that for any continuous amount of time, like in a time trial. Also the IF is NP / FTP, so if it was a really "spikey" ride then the IF will be higher, and that too is an indicator of good anaerobic capacity, but not necessarily an FTP that is set too low. Or your FTP could be set too low, I'm not trying to discount that possibility, just give you other explanations.

Edit: I've had some 4+ hour rides that were pretty close to .9 but none over.

this could go poorly for me, but........anyone log none cycling workouts in WKO?

i dabble in a little running this time of the year & use a Garmin to record the efforts. WKO+ can compute running TSS based on the data. i recall reading somewhere that folks were creating seperate profiles for different activities. not sure why though. later.

Re-read the book. I think you'll see they say do the 5 minutes at threshold, not all out. Big difference there.

Being new to the power meter, you likely don't know how to test 5" and almost certainly don't know how to test 1' power. Play around with sprints some. Do shorter ones so you can do a several without messing with your workout. You'll learn to feel what's a more powerful pedal stroke. that will help out your 5" power test, just with form.

For the 1' test, you need to start off with a 100%, and stay on it, all-out, until 1:02. Every single pedal stroke needs to be as absolutely hard as possible. No pacing at all, just explode and keep clawing away at it. Fight it until the end, and go 2" longer to make sure you capture the best 60" in there.

The 1' test should ruin you for the day, and there should be no way you'd be getting an effective test at any other durations after it. You can do a real 5" test during the warmup for the 1' test, just make sure not to go longer than 7" so you can stay fresh for the 1' test.

Check out this thread to see the shape of a 1' test: What's your WRI™ look like?

I don't know about all that, but I do log my MTB workouts when I don't have a PT.

I just create a workout from the calendar, save it, then edit the TSS from the calendar.

Uh oh...I've been using GC all season...importing tcx files from Garmin Training Center (use a Garmin Edge 500). Without scrolling through previous pages, what bug are you referring to?

I do note that the "time ridden" can differ between GTC and GC (I think GC includes auto pauses and starts/stops as time ridden), which could impact IF and NP and TSS. I also noted today that average HR can differ by 2-4 BPM between the two.

You're very close.. It impacts everything. This bug kicked in in version 1.3. Basically, any missing time stamps are interpreted as lost data due to smart recording, and so GC tries to guesstimate the missing data. It'll affect time ridden, AP, NP, tss, average hr, average speed, everything except distance. It's kind of annoying..

The solutions are to:

1. turn off auto-pause

or

2. turn on smart recording (I guess, maybe not work though)

or

3. edit and fix your ride via the ride editor when you're done.

the actual bit of code (the ifdef is my quick and sleazy fix):

if(deltaSecs == 1) {
// no smart recording, just insert the data
rideFile->appendPoint(secs, cadence, hr, distance,
speed, torque, power, alt, lon, lat, headwind, lap);
**
else {
#ifdef SMARTRECORD
for(int i = 1; i <= deltaSecs; i++) {
double weight = i/ deltaSecs;
double kph = prevPoint->kph + (deltaSpeed *weight);
// need to make sure speed goes to zero
kph = kph > 0.35 ? kph : 0;
double cad = prevPoint->cad + (deltaCad * weight);
cad = cad > 0.35 ? cad : 0;
double lat = prevPoint->lat + (deltaLat * weight);
double lon = prevPoint->lon + (deltaLon * weight);
rideFile->appendPoint(
prevPoint->secs + (deltaSecs * weight),
prevPoint->cad + (deltaCad * weight),
prevPoint->hr + (deltaHr * weight),
prevPoint->km + (deltaDist * weight),
kph,
prevPoint->nm + (deltaTorque * weight),
prevPoint->watts + (deltaPower * weight),
prevPoint->alt + (deltaAlt * weight),
lon, // lon
lat, // lat
headwind, // headwind
lap);
**
#endif
prevPoint = rideFile->dataPoints().back();
**

Some Garmin devices (i.e. edge 500s) use smart record when there's no power meter, and there's no way to turn that off.
So yea, supporting smart record is a good thing.
You should post on the mailing list and talk with the guys who have been working on this. Just turning off the smart record interpolation isn't the right way to go since it'll make any ride recorded without power (on a smart record-forcing device) useless.

I know.. I'm actually just about done with a fix that involves a configuration option. IMHO, it's the only real way to fix it without changing a bunch of logic.

Thanks for the help so far guys - this is an ongoing learning process.

Well, for the prescribed workout, I was pretty well rested ( I think ) - I was off the bike for 2 days. I pretty much followed the workout as outlined in the book I'm using ( Training And Racing With A Power Meter ). I did mess up the 1min test initially, but rested ~10mins ( 70% of FTP ) and then re-did the 3 x 1min "All-out effort" intervals with 3-5 minutes in between. Perhaps by the second, correct attempt, I was spent - I sure did feel it.

After that test, I felt like I've never before. Legs hurt, and just an overall feeling of weakness.

Thanks for the link. If you read my reply to Issaquatch, I think I found the reason my the results were suspect. I think I need to study these workouts more, and maybe even laminate the workout onto a small card to mount on the bike someplace for quick reference.

On a separate note/question, how do you guys do specific workouts on public roads and not get interrupted by traffic, turns, stops, etc?

I live in a pretty rural place ( less than 2K people ) and still had issues not being interrupted. Is the trainer the best scenario when it comes to precisely following a specific workout?

Thanks again guys
