Just finished watching Le Bike, following the original 1923 TdF route in the same time frame - 28 days? What blew me away, other than the unreal mileage (about 150 miles/day) was the first stage in the Pyrenees was 200 miles with 20,000’ climbing in one day! And this is on the original heavy period bikes where to change gears, they had to remove the back wheel and manually move the chain to the sprocket of choice. Many didn’t finish since it was more a race of attrition.
