Bike racing is not like running a 10km where you go as hard as you can for the distance.
In bike racing you go as hard as SOMEONE ELSE decides to go for as long as THEY decide.
Riding at threshold isn't that hard.  Riding significantly above threshold for an indeterminate period of time - that can be pretty ugly... K Metcalfe

"A while back I worked like a dog on my bike (55 miles a day minimum), recorded my weight, calories, and percentages of fat, protein, and carbohydrate for every morsel of food that went into my mouth, and all that time I was struggling to constantly improve my tracking of every aspect of my nutritive life.

It was brutal, and I did it for an extended period of time. I eventually achieved what some were calling my high-school weight.

Immediately people started telling me I was naturally thin." Bob F.

Look what happens when you put your bike in different positions in relation to other riders or objects while travelling at 40kph...
