To clarify: I'm not interested in training in 'excessive' heat or conditions likely to cause heat exhaustion, and I was not asking whether heat affects performance.

Within the normal range of conditions RPE and HR vary when training at a given power.

Is there any evidence that RPE or HR during a session is a better indicator of the fatigue generated than a measure based on power, like TSS?

Being honest i dont know the answer to that question.

However i would be very surprised if you did two identical power level workouts at different temperatures and achieved a wide variance in positive adaptions between the two- no matter how much more tired you felt during the hotter one(within reason obv.)IMO

TSS for me FTW
