Monte Serra rises above Buti on the eastern side of the Monti Pisani, taking you from the town towards wooded slopes. The first kilometres are purposeful: you gain height quickly, and the climb soon feels more substantial than the surrounding low country might suggest. Settle into it and the road offers a compact, sustained effort.
The ascent runs for about ten kilometres to the piazzale, with enough changes in gradient to keep you shifting without repeatedly breaking your rhythm. Pine and chestnut woodland are part of the setting around Buti; higher on the climb, the bends and accumulating height give a stronger sense of the mountain. Easier stretches help, but the upper kilometres still require work.
This route finishes at the piazzale below Monte Serra's highest point. That is a satisfying destination in its own right, reached after a climb with very little wasted distance. It suits a rider who wants a serious ascent within a manageable outing, and who enjoys seeing how much mountain can be fitted into a Tuscan morning.

How long would it take?
Enter the power you could hold for the whole climb. We calculate a moving time from the elevation profile and the forces you ride against.
Use your intended climbing effort, rather than FTP unless you can hold it for the predicted duration.
Bike + kit includes clothing, bottles and luggage.

The science behind the calculation
For each part of the stored profile, we solve the steady-state cycling power equation for speed, then add distance ÷ speed across the climb. Gravity uses rider + equipment weight; available power is W/kg × rider weight. This uses the profile’s distance and elevation together, without mixing in another route’s metrics.
Power × efficiency = gravity + rolling resistance + air resistance + bearing losses
The resistance equations are adapted from Martin et al. (1998), Validation of a Mathematical Model for Road Cycling Power. Air density changes with profile altitude using NASA’s standard-atmosphere model. This calculator’s adaptation has not been independently validated.
It predicts travel at the power you enter, including on descents. It does not model acceleration, cornering, braking, traffic, wind, changing weather or fatigue. At altitude, choose power you can sustain there: thinner air reduces drag, but this model does not predict its effect on your ability to produce power. Profile quality and assumed equipment settings also affect the result.
