2023 Skierg Sprint results for W/kg

As noted in a previous post, the average watts generated per an athlete's weight (W/kg) for the 1000m distance is the appropriate metric for results in the Skierg Sprints. Yes, absolute power generation (as currently used by C2 for results) is relevant but it is not indicative of performance on skis...

Re: 2023 Skierg Sprint Analysis and the Importance of Weight

I took a closer look at the "time to 1000m" vs avg. power and found a perfect fit (R² = 1) for an exponential function with an exponent of -0.333. The logarithmic fit is close but the exponential function is perfect. Perfect doesn't just happen and is the result of a physical law being followed. Loo...

Re: 2023 Skierg Sprint Analysis and the Importance of Weight

Sorry, misread the Skierg numbers as W/kg when they are W... the 562 W for 20 seconds translates to 7.7 W/kg at 160 lbs (72.7 kg)... I wondered about any power measurement on snow but I would expect the value to be significantly higher than on the Skierg given the ability of the body to get into an ...

Re: 2023 Skierg Sprint Analysis and the Importance of Weight

This popped up on YouTube over the weekend (https://www.youtube.com/shorts/1yOx-1o8xFA) showing Johannes Klaebo (arguably the best cross country skier ever (at least in the sprints)) on the Skierg doing 5.62 W/kg for 20 seconds and 7.7 W/kg for 20 seconds on snow. Not sure how they got the watts for...

2023 Skierg Sprint Analysis and the Importance of Weight

The recent Skierg Sprint men's dataset allows for an analysis of the role of weight-normalized power (W/kg) in the competition. I took the available data from the results and calculated W/kg values for those athletes that supplied a weight in their profile. Of the top 100 results, 20 athletes provid...

Re: How come there is no weight category for the skierg?

This is C2's position on weight adjustments for ski erg and bike erg: Unlike rowing, the sports of Nordic skiing and cycling do not use weight classes for competition. We have seen that there can be a weight advantage for the SkiErg, but at this time do not have a formula available that takes into a...

Re: SkiErg first impressions

I'm new to the skierg as well, but coming from a cross country skiing background. My first impressions are: 1. The skierg motion is not exactly like double pole skiing but close enough for training in the absence of roller skiing or on-snow availability. 2.The largest difference is in the handle pos...
