Jonas Abrahamsen’s most recent masochistic Zwift session caught a bit of attention recently in the cycling press: [image] Jonas Abrahamsen Is Being a Zwift Masochist Again Here's hoping Tour de France star Abrahamsen has got a good playlist to get him through these insane indoor workout…

Nice that you know the climb too - it’s a cracker. Since starting to work in the area, I’ve been up it twice (and I’ll climb it again today) on my gravel bike. The last time was with a block headwind, so 461w only got me 16.5 minutes. I do have studded tyres on my second wheelset, so I could ride a…

You of course make a fair point. At my size, the only way I can do it is to match the watts, not the watt/kg. I’m carrying upper body muscle from earlier gym training that I can’t easily shift, and honestly I don’t really want to. 360w is 3.6w/kg for me. My FTP would be well into the 500s if I was a…

Just for the challenge. There is no point to it of course :blush:

Considering If I done 360W or 4.5w/kg (267W) for 20mins, id be setting a new FTP significantly higher than my current, I can estimate my number will be somewhat low :sweat_smile:

[image] JonInSweden: Jonas Abrahamsen Google AI says he uses an indoor FTP of 400. 360w is 90% of that FTP. So, the question might be; Can you do Juneau +1 (5x20 @88-92%) twice in a row? [Capture]

I think there would be a good many on this forum that could achieve that volume at LT1. Probably way, way more than actually know what their LT1 is! :laughing: But, seriously, that amount of work at LT1 is good work, but only that. It’s not some insane stimulus it just requires attention to nutri…

[image] JonInSweden: I would however like to propose a challenge. Choose either 360w or 4.5w/kg - how many 20 minute sets can you do? One when I’m peaked, maybe. And that’s 360 watts. I’d get no where near at 4.5w/kg.

My power meter looking at me even thinking about this……. [Principal Skinner's Pathetic _ Know Your Meme -]

If he’s riding those LT1 intervals at around 75% of his FTP, that would put his indoor FTP at 480. :neutral_face:

[image] Brennus: I think there would be a good many on this forum that could achieve that volume at LT1. Probably way, way more than actually know what their LT1 is! Haha exactly. I was impressed for a minute until I realized I’ve done 3-5 hours straight at LT1 plenty of times.

Not possible. Don’t have an indoor trainer and would rather put my nuts in a vice than spend five hours riding inside😄
