Increased effort is increased effort whether it's into the wind, climbing a hill or riding faster. All good stuff. Sounds like you increased your power output to overcome the wind. Is this a route you ride regularly? Imagine riding the same route with no wind, but at the same level of intensity and power output. How much faster would you go than normal?
It's not the same - Robert's right. You should also ride up hill into a howling gale also. That's a test !![]()
In short, no.
To elaborate, both are beneficial but both offer different training benefits. Going up short steep hills are likely to be done at a higher intensity for the shorter duration. Riding into a headwind will be of a lesser intensity but for a longer duration. Considering the most similar training sessions to these real world examples, riding up a short incline that is steep is likely to be similar to a 3-5 minute VO2 max effort, riding into a head wind (making the assumption that you increased effort rather than maintained effort and accepted the drop in speed) is likely to be more like a high tempo/low threshold i.e. sweetspot session.
What Rob3rt is trying to say is riding up a steep hill depletes glycogen at a higher rate than riding into a headwind.
When your glycogen is depleted, it will be the same.
I see you've met the forum idiot.
That is definitely NOT what he is saying. That doesn't even make any sense.
Its an 18 mile route than I can normally do easily in an hour or so
If you can ride at 18mph average then your no slouch. However no hills in practice makes terrible practice for a hilly sportive no matter what way you look at it!![]()
