I disagree with the above. Those hours are ludicrous to "maintain" weight. I'd look into visiting a coach/nutritionist/doctor if that's necessary.

The reason lots of folks spend the time and don't get results has to do with the intensity of the work. I see a lot of NC folks I follow racking up 150mi+ bike weeks and always doing weekend century rides that are still a bit "over" on the weight side. I've seen em do multiple Raleigh to coast one day rides in a year.

Looking at the rides, they're fun and great exercise.......but they're Z1 snooze fests. At best Z2 during the ride. NOTHING wrong with that. Just needs to come with the understanding that intensity matters also.

Intensity affects insulin sensitivity, metabolism, physiology, and caloric expenditure. No need to work so hard as to vomit or lie on the roadside in the fetal position. But it's gotta hurt sometimes. Even the last hour of a Z2 ride should take some concentration if you were really in Z2 for the ride.

There's people who are pretty decent Cat 3 road racers who only average about 5 to 7 hours a week on the bike.

If it's taking 8, 10, 12 hours or 150mi on the bike or 50mi running to "hold" a weight that isn't a "hill climb race day weight"..........I'd seriously research what's going on. I'm not trying to give jabs, I'm totally serious. Something isn't right.

If it's maintaining a "race weight", yeah, that's tough. But a "good" normal day to day healthy person weight ought to be simple on even 4 hours a week on the bike.
