Back to Learn Off-season planning

Off-season triathlon strength work that does not wreck your endurance

Use the off-season to rebuild strength and keep your aerobic fitness ticking over, without turning every week into another race block.

Trade race specificity for general capacity

The off-season isn't a long taper, and it isn't an early peak. Use it to rebuild general capacity, close a strength gap or two, and keep enough aerobic rhythm that your next race block doesn't start from zero.

Off-season Tri weeks have fewer race-pace sessions, more regular strength work, and enough swimming, riding and running that you keep your skills.

Keep strength work progressive and recoverable

The strength work that pays off is the work you can repeat. Pile on soreness too quickly and your next run or ride suffers, even if the lift itself felt productive.

Mi can put strength at the center of your week while Tri keeps track of the multisport side. Gym sessions and your endurance calendar affect each other, so we plan them together.

Strength maintenance still needs progression context.

A strain and load view helps off-season strength work support endurance instead of crowding it out.

Check readiness before you push

The off-season brings holidays, travel, shorter nights and a busier life. All of that changes how much training you can absorb.

An adaptive plan backs off intensity or volume when your readiness drops, then goes back to progressing once you can handle the work again.
