Chahna is a climb of 5.5 kilometers (hors catégorie). Chahna tops out at 699 m above sea level. It is located in Chahna ⵛⵛⴻⵃⵏⴰ الشحنة, جيجل, Algérie ⵍⵣⵣⴰⵢⴻⵔ الجزائر. The average gradient is 9.7% with a maximum of 14.1%. The climb has 532 meters of elevation gain.
Difficulty analysis: This 5.5 km climb is short but demanding, with a brutal average gradient of 9.7%. The difficulty lies in the irregular profile: three sections at 11% (KM 1.0-1.5, 3.0-3.5) and several at 10% create surges that break your rhythm. The final section at 6% offers a bit of respite.
Tips for managing the effort:
1. Managing the variations: Anticipate the three steepest sections (around KM 1 and 3) by easing off the pace slightly before you hit them to avoid blowing up.
2. Spin an easy gear: The high average gradient and the 11% ramps call for a suitable gear to hold a steady cadence (70-80 rpm) without premature leg fatigue.
3. Break it down mentally: Split the climb into three parts (the start up to the first 11%, the middle with the uneven gradients, and the flatter finish) to make the effort more manageable mentally.
