This is key! Also what a properly structured coach/plan will come up with - ditching the 'junk' miles many of us do, making our general riding easier, recovery type stuff to really maximise the real sessions (ie being less fatigued for them).
Anything is tough riding it for 6 hours! Mega ride & effort. Huge huge kudos for being able to get that done and on one of the most boring courses for it!
Never had issues riding the bike on the road so need to stand up more when on turbo but have also bought a new saddle to try tomorrow. 
You really do find out saddles through the turbo! I'm on my 8th and still not happy. Not convinced I'll ever be, but will keep trying!<snip> has highlighted the fact my saddle is not comfortable!
Yup, definitely move around far less on the turbo. Although I've found after I fitted aerobars and using them to vary my position (so I sit up less, just alternate hip rotation and position) I've got less numbness, which has led to less sores. Without the aerobars I used to ride upright 'hand-less' far more to (free up my shoulders). Not a position I ride on the road, the aerobars is more in line with how I ride at times on the road.

A saddle with a central cutout is something I've ventured to the last couple of years, the same one on my road bike I just couldn't get comfortable on the Turbo after 2-3 hours (doing 4-5 ok outside). Now one with a central channel (as well as a cutout) is working better. I've not done any longer rides on it, but can just tell it's better.
Am I alone (read mad) in liking the extra challenge of doing relatively hard turbo sessions of up to ~1 hour without using a fan, despite temps in the setup room rising to ~25C during the session?
I have an 18" fan side on angled up and just about keeps me okay and the room is certainly less than 25C!Maybe slightly mad! To be fair I quite like the heat, but the lack of airflow would be utterly miserable!Am I alone (read mad) in liking the extra challenge of doing relatively hard turbo sessions of up to ~1 hour without using a fan, despite temps in the setup room rising to ~25C during the session?
That can be much of it, also position on the bike can change as fitness/body shape changes, not to mention flexibility! The type of riding/roads outside obviously dictate your position, but indoors you do have to really focus more on positioning. Without the bike moving around underneath it just doesn't feel natural to change position so before you know it you can get really uncomfortable!
Ahhh, I guess it's one of those things - having direct comparisons makes things much easier. Obviously a TT effort is more measured than a hill climb and dare I say it, more measured than a Zwift race! If it was Tom then the realisation of national events may have needed pointing out - as he's dutch/belgian and may not have realised/recognised the names or governing bodies... It was far more tricky than it needed to be, in two ways I thought you got caught - changes to the system and the old having a huge backlog. In a way by going directly (like we did), I hope it sped things up - so you beat the backlog!
Ah ok. Although sounds like it might be fine for me, I'm after something I can run quite constantly. The big 18" I have pointed at my face 12" away I don't tend to run continuously as I get chills! Things will move around shortly and I'll move it further away (but will mean it goes more off to 1 side). So think the little Honeywell will fit in well. I have another larger floor-standing 20" but the airflow is insane - usually only required in the late spring/summer!**** poor for anything of any real intensity
Perfect for Z2/Z3 work but I still use my 20" floor-fan predominantly for 'proper' work.
They (two) fill a nice middle ground but I would need about 6 to match the effect of my 20". I absolutely cook and sweat buckets whether it's -5 or 25
Swift spellcheck ftw!
