What race day throws at you
Typical sessions
Ten hours of sustained power on loose gravel, holding an intensity factor around 0.68 to 0.73
About 240m of climbing per lap, roughly 1,680m over a typical seven-lap solo day
Cumulative gravel vibration and an afternoon low point around hours five to seven
Self-supported pits every lap: no on-course feed stations, so you fuel 60 to 90g of carbs an hour yourself
What your weeks look like
Typical sessions
Threshold work: 3x10min at FTP building to 3x20min, plus 2x20min sweet spot
Over-unders: 4x(4min at 105% / 4min at 90% FTP) for repeatable race-pace power
Hill repeats: 6 to 8 x 3 to 5min climbing efforts for the relentless per-lap climbing
Weekend doubles: a 4hr Saturday on gravel plus a 2 to 3hr Sunday, building to a 5 to 6hr race simulation
