I saw this power estimate for Pogi's Seixas' climb up the Redoute:



8.7 watts per kilogram, yikes!

I went to my Strava stats to see the longest time I managed 8.7 W/kg. It was on a short climb segment where I was trying to set the KOM. 40 seconds, and I was blown at the top.

40 seconds vs. 225 seconds -- not even in the same galaxy.

I guess I shouldn't feel too humiliated. I was 63 at the time, a fair amount older than Pogi and Seixas.
