45 y/old. Been riding 3 yrs now, with last two winters on TR structured plans.
Current FTP 250. Resting HR 45, max 189.
All my workouts look like the image in that my HR just climbs with every effort until it max’s out and I cant continue. Sometimes I get though the session, sometimes I dont. My HR never seems to plateau at a sustainable level.
Am now doing SSBII after reducing FTP by 30W but HR still ramps up to max every ride.
I never get any chest pain or really breathless and don’t think there’s any underlying medical issue. Just find it weird that my HR climbs to max during every ride.
Any thoughts on what’s going on?
