I know that road a little bit and it's far from optimal. It actually varies in gradient between 8 and 20+ % and the road surface isn't perfect. The descent is pretty quick so she'll have wasted less time going downhill than on some other courses, but this also means less rest. There are a couple of heavy braking sections and some undulations to take care going over. This is one hell of a performance.
VAM of 1400 ish (@275 watts!!) on first ascent - not to be sniffed at. You could hold pace in the TDF main peloton doing that.
Her effort went out crazy fast and then dropped quite a bit, and steadily from her very first efforts to her very next efforts and substantially to her later efforts. She also had some efforts at lower average watts climbing the main hill, but her time was faster than some of her earlier ascents with higher watts. It seems a little strange to me, unless she had a crazy tailwind develop 20 minutes later. Her maximum speed of 48 mph for a 10.9% grade, also seems slow. The prior female record holder hit upper 50s with a max of 62 miles per hour on her 10% grade descent. Also, she didn’t have any heart rate data on Strava. Lots of the other Everest attempts had steady watt power for most of the day. Anyway, it just seems suboptimal pacing, with nothing aero such as a road/skinsuit (which could help on descent) yet she crushed the record. Is she that good, that poor planning still crushes the record by nearly an hour?
And... per the poster above, the course is far from optimal. I’m thinking these self reported world records need more proof than a Strava file, without heart rate data.
