Chisec is a climb of 2.4 kilometers (hors catégorie). Chisec tops out at 524 m above sea level. It is located in Semuy, Alta Verapaz, Guatemala. The average gradient is 15.1% with a maximum of 19.6%. The climb has 361 meters of elevation gain.
Difficulty analysis: This climb is only 2.4 km long but brutally steep, with an average gradient of 15.1%, which puts it in the hors catégorie (beyond category). Its difficulty lies in its irregularity: after a first "steep" section (12%), things ease off slightly in the second half-kilometre (9%) before a decisive, very punchy section between 1.0 and 1.5 km, where the gradient peaks at 19%.
Tips for managing the effort:
1. Pacing the key section: Plan ahead for the 19% ramp (between 1.0 and 1.5 km). Hit it with fresh legs by holding back on the first kilometres, even though the gradient is already significant.
2. Choosing the right gearing: The 15% average and the 19% peak call for a very low gear ratio. Run a small chainring and a cassette with a big sprocket (e.g. 32 teeth or more) so you can keep a sustainable cadence.
3. Saving something for the finish: The last 400 metres at 6% give you a real breather. Use that stretch to recover a bit and pick up the pace again before the line.
