You can't include 70 kilometres of TT's any more, since the mountains don't create enough gaps any more with the current gearing to level it out.
That said less than 20 kilometers of TT's in a grand tour are beyond comical as well.
The Giro d'Italia used to do it properly for long years. Having a good, long TT and enough mountains to let it swing one direction or the other.
The 2020 Giro d'Italia still had a perfectly fine route that created a well deserved winner in Geoghegan Hart due to the final TT.
Dunno why Vegni has lost it that much the past editions.
the mountains at the tour sure had no problem causing big gaps. The riders actually RACED instead of sucking wheel until 1.5k to go
stick 115km of flat ITT, the climbers will be forced to attack 3 climbs from the finish once again
