During this past off week, I've had the opportunity to conduct two power tests intended to determine FTP and reference for training zones into the late base and early build months ahead.

Wednesday was a professionally administered ramp test (100w @15w/minute) with two days of rest and ample motivation/preparation. Failure occurrred at 360w, while the test administrator has yet to give me my "official" ftp number, she estimated it at around 315w.

Saturday was a time trial over 9 miles which I treated as a 20 min test (but really took 25 mins. to complete) . Again, two days off, adequately nourished and similarly motivated. Avg. watts = 285. There was no drop off in power between minute 20 and 25 which leads me to believe it could be used as a reasonable proxy for a 20 minute effort.

30W discrepancy...

Some caveats:
-my first ever TT effort at that duration (went out a little too hard initially), but I really felt like it was 100% of my effort the entire 25 minutes.
-not a lot of training time spent near my previous LT wattage.

Of course, I could try to do a series of confirmatory workouts that would play with those two ranges, but I've surprised myself many times this off-season performance wise.

Which level seems accurate, and why?
Were you in an aero position for you TT? If so, have you done work in this position frequently this off season?

Is there a way to estimate your wattage without any power measuring equipment?

ie, by average speed over flat terrain, etc...

Not for any useful purpose... but the best way to estimate is to a steady effort up a consistent grade, because it isolates (or reduces) the most variables

How do you estimate watts with a climb? Lots of algebra + known variables?

Just a general question: When you guys are on group rides w/ teammates, do you leave the PM in avg. watts or do you leave it showing actual wattage at that point. I usually leave in avg. watts screen so I can pace myself, which usually works well for me. If we do jam sessions are then I will put it in interval but still look at avg. watts. My coach generally leaves it in actual watts screen and only uses the intervals when we do them on the road.

I bring this up, b/c today on a training ride we were doing TTT practice and one of my teammates whos a TT specialist took a really long and hard pull and wanted to know what wattage I was putting up during his pulls. I had my PM set up w/ avg showing; I wish I could have told him the real numbers....

Argh. I tried using my Ptap in HR mode so that I could use it on the cross bike. I also set it to calculate time based on receiving HR data. Even though I always saw data displayed, it lost an hour in there somewhere. Not a big deal but I'd like to capture that info in WKO to see a correct weekly duration. I know that I can manually estimate TSS but couldn't find a way to edit the duration of the ride.

Finally paying some attention to Performance Management Chart on WKO+. I'm not sure I "calibrated" my CTL, ATL and TSB scores at the beginning of the season and can't tell if the numbers 1) mean anything or 2) can be interpreted by someone else (i.e. I have a TSB of -6, do I need a break?)

There are settings (CTL/ATL constant, starting values) but have no idea if they are correct or can be "back dated" so that it gives me correct numbers based on my training today since the start of the season.

P.S. I never really stopped riding or had a long layoff to get nominal baseline values. Does this matter?

thanks

i have a garmin 705 head unit. on page one, the main page i have 3 second avg power showing. bascially real time with some smoothing. on page two i have avg pwr for the effort. i rarely go to page two during ride though. later.

after you've used wko+ for a few more days than the "time constant", then ATL/CTL mean something. i.e. after 2 weeks your ATL is "right". Unfortunately the time constant on CTL is default 42. So if you've only used it for a month, it's not built up to steam. You can just set it to a starting value of something you think is reasonable, and then the CTL is pretty significant. Also, -6 TSB is not generally something to worry about. That just means that you are doing approximately as much work now as your body is used to. -20 or so I think is significant. Depends on the person

should a max 5min interval be an Anaerobic Capacity effort, or should i re-adjust my FTP?

That looks like a mean-maximal plot except where it turns up as it goes to the right. How was it generated?

For a 5' test, it's probably good to start pretty hard (well into the AWC area) just to get the benefit of those systems, but no so much that you can't maintain a significant VO2Max effort for the remainder.

Do you have some test data to share?

I uploaded 2 crits and 1 road race into garmin training center, then exported the files and uploaded all 3 into cheetah, then ran the CP plot page and it spit that chart out...

It looks like all it's doing is taking a Monod method to figure out the curve based on several averages from your rides.

Speaking of golden cheetah and garmin, has anyone figured out why some can't get the power data from a garmin connect export (edge 500)?

With help from the forum I got it to work... this is what you must do:

1. upload your data to connect.garmin.com (gc)
2. export the tcx file from gc.
3. inport the tcx file into garmin training center (gtc)
4. export the txc file from gtc.
5. inport the txc file into golden cheetah.


enjoy !

Awesome, I'll give that a try. Thanks!



Edit: Sweet, it worked.

I did this to figure out how I should pace myself in a 2.75k TT this Saturday.

Peak 5min (334 watts):
Duration: 5:01
Work: 100 kJ
TSS: 13 (intensity factor 1.249)
Norm Power: 325
VI: 0.97
Pw:HR: n/a
Pa:HR: n/a
Distance: 1.805 mi
Min Max Avg
Power: 106 683 334 watts
Cadence: 36 124 93 rpm
Speed: 8.1 32.4 21.5 mph
Pace 1:51 7:26 2:48 min/mi
Hub Torque: 22 397 111 lb-in
Crank Torque: 106 1131 308 lb-in


5:20 (307 watts):
Duration: 5:20
Work: 98 kJ
TSS: 12.6 (intensity factor 1.19)
Norm Power: 309
VI: 1.01
Pw:HR: n/a
Pa:HR: n/a
Distance: 1.952 mi
Min Max Avg
Power: 162 666 307 watts
Cadence: 29 149 93 rpm
Speed: 10.1 31.2 21.9 mph
Pace 1:55 5:58 2:44 min/mi
Hub Torque: 40 302 101 lb-in
Crank Torque: 97 1157 292 lb-in

5:03 (326 watts):
Duration: 5:04
Work: 99 kJ
TSS: 13.3 (intensity factor 1.255)
Norm Power: 326
VI: 1
Pw:HR: n/a
Pa:HR: n/a
Distance: 1.792 mi
Min Max Avg
Power: 0 671 326 watts
Cadence: 35 156 91 rpm
Speed: 5.5 38.5 21.2 mph
Pace 1:33 10:58 2:50 min/mi
Hub Torque: 0 430 110 lb-in
Crank Torque: 0 1490 313 lb-in

The second interval was a failure because of ice around a turn and losing track of time.

My FTP is set at 260. My anaerobic capacity zone on WKO is 318 and up. I thought a 5min effort might be a VO2 max thing.

If you don't care about having your data in Garmin Connect, you can just skip steps 1-3 and just download from the 500 to training center (and then export the tcx for Golden Cheetah). The problem seems to be the tcx files generated from Garmin Connect (from the 500) don't play well with golden cheetah.
