    quick one -

    At the end of a ride my garmin will read some number for TSS, say "98", I upload to Training Peaks, and the number is magically "113."

    Why, and which one should I trust more?

    Most likely a different window of time used for the calculation. If so, it's not like one is less trustworthy, they are just measuring slightly different things. Probably a case where consistency is more important than (unattainable) "accuracy".

    Take advantage of the PM consultants.

    well, if anyone can get me a good deal on an old Duraaci 7800 wireless (preferably with the 130/110 bcd), that'd be swell.

    while i trust the old PCV stuff, the displays options leaves something wanting.

    First, check that your FTP numbers in Training Peaks and on the Garmin are the same.

    I would think Training Peaks has the calculation more nailed down since they've been doing it/tweaking it longer. Isn't TSS from Training Peaks, essentially?

    But the bigger question is does it really matter - as in, does seeing TSS during a ride have much effect on your training?

    Glad to hear you're training though!! When's the next RR?

    I use the Garmin TSS often on training rides when a TSS maximum is specified by my coach. Two instances where I have gotten yelled at are recovery rides and openers. Keeps me in check.

    all - Thanks.

    1. TP and Garmin had slightly different FTPs noted, this may be part of it.
    2. I mainly use TSS on TP for the predictable stuff, but it has been disconcerting to see TSS on the garmin at the end of a ride, then 15' later, see a meaningfully different number. Yes, consistency is king, and I've always stuck w/ the TP number.

    Matt - don't know, it depends on me getting into a job that pays a bit better. I can race track for $10 a night w/ almost no travel expenses... RRs cost a bunch more (both $$ and opportunity cost). I am back to training, and between "sensations", training #s, and track racing results, I'm coming around. Late September here I come!

    This is definitely it. TSS is computed based on your FTP.

    TSS = (sec x NP x IF)/(FTP x 3600) x 100

    Different FTP value gives different result.

    Not exactly new to power but this is power related.

    I've been doing alternating workouts between 2x25 and 3x25 at various power levels. Generally the 3x sets are maybe 95-97% of FTP and the 2x's are maybe FTP + a few (2-4%) on a good day.

    I'm questioning the value of the FTP+2-4% workouts. I guess the question is whether I would see bigger FTP increases by doing more of the volume at slightly lower power levels?

    practically speaking if my FTP is 300, I could do a LOT of time at 285 (110+ minutes), but once I try to go much above 300 watts, I'm really limited to 50 minutes total workout time and I'm pretty fried. My goal right now is to built up FTP as much as possible in the next 30 days. I'm probably asking the obvious here.. Should I scale back on the more intense intervals and go lower and longer? I'm generally looking at 2 real good ride days a week, so I have to pick carefully.

    Are you targeting an event with a steadystate effort?
    I'm sure when you were getting to the point of blowing nothing was obvious but making the pain stop...I don't know about you but after the fact I always look back at those moments and think 'why didn't I just keep going' but at the time there wasn't enough oxygen on the planet to make me take one more pedal stroke.

    The biggest one that is a real race is at the end of August - Green Mountain stage race, so it's still some time away. I have a few 30-45 minute TTs between now and then.

    I'd choose an intensity you can murder for approximately the length of time your priority steadystate efforts are. Unless they're under 30 minutes.

    So if your priority event is a 40km, i'd choose 2x30 since it'll be approximately an hour.

    if it's 20 minutes, i'd go 2x20s.

    etc.

    I bet your FTP isn't 300.

    consensus seems to be that a mix of push and pull workouts is good. at least that's what i've seen. i definitely wouldn't get rid of the FTP+ workouts...at least in my experience, those really seem to help.

    have you raced GMSR? if it's the same as it was two years ago, the TT is short. roughly 15-20 minutes. it starts uphill and then levels out/goes down near the end, so it's not an FTP effort. it's probably closer to VO2 max on the hill, followed by whatever you can sustain to the finish. as for the RR...well, yeah. big FTP will help keep you fresh for that big climb at the end.

    sorry I should clarify, that's 110 minutes worth of intervals (4x27 with 10-12 rest), Not in a row. It's in the range there, because I need to try very hard at intervals if I go much above 300, but at/or below I can sustain for a while.

    I've done the race a few times...The hill I train on is the opposite side the hill stage finishes on and when we get closer, I'll do more training on that side. I'd like to hang with the top10 cat3 on the finishing climb if possible. I have a lot of work to do though.

    The TT is tough too, and I'd like to do well but will worry about that a little later. I agree, my pacing for the TT is go out pretty hard and try to hang on. I can climb a lot better than I can go flat/slightly downhill on the TT also.

    Alright thanks, for now I will try to do the more intense ones earlier in the week when I should be most rested.

    Does anyone know - can I use a PCVI with a Quarq?
    I know that SRM did partial ANT on the PCVI, and I recall hearing talk about Quarq issuing a firmware update to make their units PCVI compatible, but now I can't find the article.

    I don't think so.
    In fact if I am not mistaken neither will a PC7

    Had an issue with my Powertap today that happened once before about 8 months ago. I will be riding and for whatever reason the power reading drops way below what it should be. For instance, I will be softpedaling but certainly applying pressure to the peddles (maybe pushing 100 W) but the reading comes to zero. It remains like this for a few minutes and then it returns to normal readings. It is not much of a problem I guess but I wonder if anyone else has experienced this and found the cause/remedy.

    I've actually been seeing the same thing lately, only on recovery rides where I'm going SUPER easy, like 50-100 watts.

    In my case it shows 0-20w when I'm doing more like 50-100, and cadence will drop to <10 or 0.. I'm hoping my issues is batteries.

    How old is your PT? Mine is about 4 years old, but I got a new transmitter chip a few months ago..

    My "plan" is to wait for the batteries to poop out, replace 'em, and hope for the best.

    Mine is about two years old. I just replaced the batteries a few weeks ago.
