Untrained FTP
 

What would generally be considered a high FTP (w/kg) for someone who is untrained with no previous riding experience? I'm currently at 80kg.

Uh, maybe 6?

Dunno, don’t track that but have no problem with those than do.

sorry, it was a wasted post but was feeling snarky. Thanks for helping me work through it. :D

If you find you're >5.5 start contacting the World Tour teams.

The plot below has the 50 percentile at somewhere between 3.6-3.7 (if I'm reading the chart correctly) and the same for men and woemen. And this seems a little on the high side to me for both genders. So I take the percentiles here with a grain of salt.

Here is a plot of selected TrainerRoad users from 2014. Assume (1) if you're on TrainerRoad you're fairly serious about cycling (2) people accurately report their weight on TrainerRoad. Here the average FTP is ~3 with ~1000 data points although results for men and women might be mixed together here. I think this corresponds with some aggregated data w/kg FTP on the Garmin web site as well.

A totally untrained ftp for someone of 80 kilos may be around 80 watts.

Yep.
1 watt per kilo. Probably less though.
That's my guess.

I think the above chart is pretty charitable.
Someone here will tell me I'm wrong.

Welcome to Bike Forums!

Darn! I missed it by "that" much.

First off - Welcome to Bike Forums.

Your question is a little too generic and so you suffered the humor/wrath of some of the Gent's here.

Joe Friel has written some good books and I've one on Power Meter training in front of me right now.
He offers a method by which to estimate FTP using the following factors.

Your lean weight (as in not your actual weight, but what you should weigh)
Sex
Age
Altitude
Number of days per week you train

But this is still just very rough numbers.

If you use a Heart Rate Monitor & suitable software/hardware then Strava will actually give you estimated power for you rides.
It's a cheap way to get an indication without the investment in a Power Meter.

All the best

Hate for you to be disappointed because I care and also want to be the first to say.... Your wrong!

What was the subject again?

Ha! Thanks. You made my day.
:D

I don't allow untrained FTPs anywhere near my domicile. Messy things, they are.

High FTPs? As in a power you could legitimately hold for 45+ minutes?

3 w/kg would be a pretty high FTP for someone untrained, so around 240w?

After a few months of deliberate structured training, I'd expect around 4 w/kg or 320ish watts for a "high FTP". After a year or two, if you were really quite good, I'd expect around 5, or near 400 w/kg. Clearly those people are really quite rare and/or have an extensive endurance background, though, so I most assuredly would not expect anything close to that.

If you're talking about your average person who could lose 20 lbs and hasn't done much more than walk to the fridge in the last few years, than anything between 1-2 w/kg would be expected, so somewhere between 80-160ish watts.

And if you don't have an actual power meter, absolutely none of that matters a bit. Strava estimates or whatever are genuinely useless for this type of question.

3W/kg.

1.6 - 2.6 W/kg is more typical based on personal experience with a power meter while I was out of shape.

20 miles in one hour solo is the benchmark for a fit recreational cyclist which takes me about 210 W.

An 80 kg rider dragging 18 kg more around would use 23 kj extra, or an additional 6W.

Doing it comfortably on 95% of FTP they'd have about 230 W which is 2.9 W/kg.

Riding a lot but not training my anaerobic threshold, I could just manage 10 minute intervals at 200W suggesting a 180W FTP. When thin by normal people's standards I weigh 150 pounds which is 68 kg. That's 2.6W/kg.

After not riding for six weeks while a broken collarbone healed, I could only produce 164W for 10 minutes suggesting a 147W FTP. The average American male weighs 198 pounds which is 90kg. That power and weight would be 1.6W/kg.

Conversely, in great shape I can manage a 220W FTP at 62 kg which is 3.5 W/kg.

I actually do have a power meter, which is why I asked the question. Just trying to see where I'm at. Thanks for your responses on this thread and the other one I started, they've been pretty helpful.
