How it's worked out
On the road's own profile, stretch by stretch: the speed your watts hold on each gradient against gravity, the tyres and the air, which thins as the road climbs. A road bike on the hoods, good tarmac, no wind, and 2.5 % of your watts lost in the chain. Wind, heat and a start too fast all change the real thing: this is the time of a steady, even climb.
Try your pace indoors first
Grimpa draws the real road in pixel art, and your smart trainer feels every gradient. Set the pacer bot to your W/kg and see whether you can hold it to the top before you go.
