4W/KG!

After a personal record up Alpe du Zwift today, under 50 minutes for the first time, I have bestowed the 4W/KG achievement on myself.

After the the ride (consistent with how I always weigh myself), I came in at 144.4 pounds, or slightly higher than my Zwift weight of 143 pounds. Using my actual weight, 4W/kg = 261.8 watts.

Doing 266 watts for 48 minutes, I got these FTP projections, all of which are above the 262W threshold.

• Intervals.icu: 264W
• Xert 268W
• Zwift: 263W

If I had done just 245W for another 12 minutes, I would have still surpassed 262W for one full hour. I feel comfortable saying I could have done that.

After 8 years, it’s a great achievement, but also doesn’t change anything. It’s just nice to know I was able to do it and I want to keep going and apply it in the real world.
