I basically follow the periodization scheme in the triathletes training bible. So in the transition/prep period which I basically take as the off season. I'll take two weeks off totally. Then I when I start training I do just some weightlifting mainly, 3x a week maybe 10h/wk in total. The time off and training a little might be like 5 weeks total.

Then I'll start doing 3 week blocks of training, so after the 3 weeks I take a recovery week about 10h or 50-70% of the previous week.

I'll start base training where each block I'll increase the volume about roughly 20% each block. So this year I'll go something like 10h-13h-16h-20h-23h per week in each block in base. I'll reduce the weightlifting and I'll start doing more interval sessions. Then I go into build training blocks where I'll lift rarely and do 2-3 interval sessions a week total like 18h/wk probably until a race which I taper for. Any feedback would be nice.

Historically, most of my performance gains have been made in the "off-season".

For me that was running then swimming. Typically November was getting back to regular training for running then build up a little volume in December. By Jan-Feb I was pumping out VO2 max and threshold intervals.

For swimming I would just do whatever my masters team was doing, or if on my own I'd follow the schedule in the book "Swim Workouts for Triathletes".

January I would get back on the bike and by Feb-March I'd be into VO2 and Threshold intervals.

That would progress through April-May, after that was racing season where I was just maintaining fitness.
