How long can you hold 600 watts?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

There used to be a rumor going around that Lance could hold 600 watts for 30 min. Don't know if it's true or not but we all know that he once generated the electricity for Sports Center. I know because I saw the commercial.

400 watts for an hour isn't that rare for top flight cyclist. The peak would be above that someplace. 600 watts is half again as much, though the shorter duration might help, so I don't know either way whether to accept or challenge the number as impossible.

OTOH- here on earth for the rest of us, 100-125 watts sustained for any decent length of time is pretty good.

One indicator someone can use to approximate their wattage capabilities is average speed over level ground. There are wind speed to wattage conversion programs out there, and though each of us has a different coefficient of wind drag, they'd at least have you in the right ballpark which should be good enough for most bar bets.

The hour record (one of the recent ones) was like 480w for an hour. Thats pretty insane, I doubt I could hold it for more than 2 minutes.

About 90 seconds is my best since I got a power meter. As of right now, probably about 45-60"

600 watts translates to between 30 and 35mph. I couldn't produce that at all even in an all out sprint. Looking back, I figure my peak output for 10 seconds or more is probably about 500 watts (on a good day), and sustained for a minute would drop to 350 or so. For half an hour, I'm at the high end of average earthlings at about 125 watts. My lifetime best sustained (1 hour+) output was probably nearer to 250 watts, but that was a long time ago, and I was very highly motivated.

You'd have to be around 60 pounds to peak at 300watts. It's not as hard as it seems. Most likely everybody can put close to 1000 watts for a few sec.

I agree that we can produce peaks that high, but I question the sustainability. My 10 second estimate at 500 watts might be conservative, but I strongly doubt I could sustain it for a minute, and certainly not for multiple minutes.

(BTW- I've since edited the post. the 300w figure was based on using kph vs. mph when working back from speed.)

^this

According to my power meter data from my ride today, I held ~600W for about 30 seconds. My peak output during a sprint was 900W. (and I'm a 140lb weakling more suited to climbing)

Hmmm.... So if one adds half again as much blood as one is supposed to have... that might be about right

Hopefully I'll get a power meter up soon. I can't wait to see how much power I put out just riding to the end of the driveway.

I definitely agree with you, Che Catso.

Nah, I have to disagree. Most people put out more power than that, they just don't know what they are putting out. I'm a very average amateur IMO, I race Masters 40+ but usually finish mid-pack (meaning I suck for the most part). Here's a breakdown of my 58-min ride this afternoon:

I basically spent over 75% of that time well above 125W, and that is including riding through small villages and getting stuck behind old people. Don't sell yourself short, you probably put down a lot more power than you think you do. In fact, most people probably do. It was an eye-opener for me when I started training with a power meter.

Yes, but you're an athlete of some sort. Look around you. Most people (not most athletes) have no hope of producing anything close to what you as a mediocre (your description) cyclist can.

+1 100-125 watts is a very easy recovery ride.

It used to be relatively easy to hold 600 Watts, but then they stopped making 100 Watt bulbs. So now instead of holding 6 bulbs, you have to hold 13, which is way harder. You could leave them in the package, but that seems like cheating, and no one in cycling cheats to hold more watts.

You'd probably be surprised how much power you could average for 1 minute if you were rested and paced yourself right. What I've heard is that most people don't try hard enough on all out 1 minute efforts.

If I remember correctly, in the '06 edition of the Tour, (and before he came clean) Floyd said he didn't really attack (stage 17 I believe it was). He merely rode at a wattage that he knew he could hold for x amount of time and no one went with him. I believe he said he kept an eye on his power meter and rode at 400w
