Beina integrates directly with your existing tools to understand your current fitness, and synchronise your planned sessions.
Intervals.icuThree sports, one hour
Typical sessions
A 4km opening run, long enough to bury you if you go out too hard
11km of MTB trail at threshold, steering the bike while your heart rate is pinned
A 2km closing run on brick legs, the hardest 2km you will run all year
Two transitions, where 30 to 60 seconds is real podium time
What your weeks look like
Typical sessions
Run intervals like 5x800m at 5km pace and 4x1km at 10km pace for economy
MTB threshold work: 3x10min at 95-100% FTP, plus an all-out 11km time trial
A weekly brick, building to a full race-pace mock of run, bike, run
Dedicated T1 and T2 drills until each transition is under 30 seconds
