What Franja throws at you
Typical sessions
~156km and roughly 2,300m of climbing over 4.5 to 8 hours in the saddle
Two decisive climbs: the 4.6km Vrhnika hill early, then the ~7km Kladje at 6.3 percent that ramps to 10
Constant energy-sapping undulation through the Idrija and Cerkno rolling middle
June heat, 25C plus on the climbs, with afternoon mountain storm risk
What your weeks look like
Typical sessions
Threshold on a climb: 3x12-15min at 95-100% FTP on a real hill for sustained Kladje power
Long sweet-spot: 2x25min at 88-94% FTP to build sub-threshold climbing durability
Climb-on-tired-legs: a 4-5hr ride finishing with a hard 7km climb, rehearsing Kladje on empty legs
Race-pace long ride building to 150km+ with 2,000m+ climbing, fuelling at 60-90g carbs per hour
