Climbing up the mountain you are doing extra work relative to the flat route. At the top you will have accumulated potential energy. In order to break even with the flat route you will have to convert all that potential energy into motion, without any loss. This is not possible in the current universe due to the third law of thermodynamics. On the ...

Say you can keep a 30 kph pace on a flat straightaway. On a hill, that can drop to 10 kph or even less depending on the grade you have to climb. Call it 1/3 of your flat pace. Say that half your run is uphill and the other half downhill, and let's also say that the total run is 30 km. If you run on the flat at your regular pace, it takes one hour to do that ...

Yes, there has been tons of in depth analysis on this, and the equations are rather simple so you can answer the questions for yourself given different scenarios using the Equations of motion for cyling Assuming you are on a road bike, on a flat road, with reasonable tires, the vast majority of energy is overcoming aerodynamic drag, about 70-80% After ...
