Thanks for the responses so far. I have a couple of fans in use, not the most powerful on their own but in combination and with the door open in the British autumn/winter time I haven’t found any issues with overheating.
As Bbarrera states i’m taking my LTHR from previous experience rather than TR workouts, and am quite confident about the zones. What I understood to be my ‘SS HR’ was spot on coming into SSB1 and same for threshold which I encountered with a few of the over/under workouts.
It may be that the ramp test has slightly over-estimated my FTP based on what you guys are saying, but it just seems strange than when doing some 10-12 minute 99% FTP intervals I didn’t experience any real leg burn that I’d expect from riding above FTP. The burn I mean is the type typically experienced when doing the over part of over/unders. So effectively the perceived exertion feels about right, it’s just the corresponding heart rate is higher…
I’ll keep an eye on it and report back in case of any changes. I remember on SSB1 I found the SS intervals much harder at the start of the block than by the end when I felt better adapted to the work so it may be that this is a by-product of adjusting to the new higher workload and may settle down in the coming weeks.
Cheers,
Henry
