Thank you excellent read and I'm a fan of hers.
My name is Thomas and Annika is my better half. I've been riding since the early 90's but was never as successful as Annika. So I had to come up with something else to do. That something else turned out to be studying which led to a phd-position at the University of Copenhagen with Nikolai Nordsborg. The guy that got me into all this studying and research however is Carsten Lundby. A professor at the University of Zürich, my co-supervisor, a keen athlete and good friend. Today I work as a coach for some talented riders (Simon Andreassen, Sebastian Fini and Andreas Kron among others) and am very much influenced by the time I've spend with both Nikolai and Carsten.Who has written the text, her coach? There is no author given.
I assume you mean Zones 3 and 4 for Tempo and Threshold. Is 17-19% a lot of time?aren't all Elite Scandinavians training polarised? I see so much tempo and threshold in her TID. I guess she didn't get the Seiler memo ;-)
140lb seems heavy for those power numbers. I would suspect that to win with those numbers that race weight is between 130 and 135.I'm more interested in knowing her NP for those events. Average power doesn't do much. Also, I just did a quick search and she's listed at 5'9 and 140 pounds. Not sure how accurate that is.
At first glance 140 at 5'9 does seem a little high considering I'm 5'8 and when I'm 140 I'm still not super lean. I don't know what a top female at that height *should*, but I'd expect less.140lb seems heavy for those power numbers.

I actually find average power is a better predictor of placing then NP for XC racing. I have a ton of power files and done regression analysis of both norm and average and found that average watts/kg is a better predictor of finish than NP/kg.At first glance 140 at 5'9 does seem a little high considering I'm 5'8 and when I'm 140 I'm still not super lean.

I still don't know what kind of insight avg power would give you for an xc race. You are neck deep in this stuff - what kind of np would you expect from her given those avg power numbers?
Not to put words in your mouth, but:I actually find average power is a better predictor of placing then NP for XC racing. I have a ton of power files and done regression analysis of both norm and average and found that average watts/kg is a better predictor of finish than NP/kg.
I would expect that her NP for S.A. is 4.5-4.9 watts/kg.
I think the Norm Power algorithm isn't that great for mountain biking. Mountain bike racing, particularly WC MTB racing, is super high wattages followed by zero watts. I don't think the algorithm was designed to model that type of racing. Works great on road, but not as good on the dirt.Not to put words in your mouth, but:
Is AP/kg better than NP/kg because it might indicate a steadier effort? And, might NP be indicative of working through a lot of traffic? Surge, pass, recover, repeat?

Interesting, I wouldn't have thought this was the case. I was thinking along the lines of average power not being as useful because if a rider was smoother with less braking, and therefore less accelerating, they would show a lower average power; thus not telling an accurate overall story.I actually find average power is a better predictor of placing then NP for XC racing.

This is interesting to note given Miller's findings (below) that intermittent power seems to predict XCO outcomes better than FTP. And this seems to agree with LMN's observation of high watts/no watts efforts in XCO. I don't know the NP algorithm in detail but my former coach tells me it tracks better to intermittent power than average power; which would lead me to believe NP predicts XC success (intermittent power) more so than Avg Power. I've got more to learn.I think the Norm Power algorithm isn't that great for mountain biking. Mountain bike racing, particularly WC MTB racing, is super high wattages followed by zero watts.
