Hello, Pigale!
It is very warm here!
I agree with you about Raymond Poulidor the "eternal second"!
Everyone loved him. Anquetil was a better rider but the French people loved Poulidor, and tolerated Anquetil.
I have read Anquetil's biography " Sex, Lies, and Handlebar Tape". It is very good, especially describing his ferocious will to win.
Yes, Tom Simpson died on the ascent of Mont Ventoux.
Amphetamines and alcohol were found at his autopsy.
They, and heat exhaustion, caused his death.
