Off season

I prefer working on a specific weakness or doing a specific block.

For example we have masters championship swim races in April. That was a focus a couple of years back and it carried well into the tri season for short course.

If I was doing an IM, I would do a very specific bike focus over the winter, do a lot of easy miles on the run to build a good base and swim a little more than average. The mix is definitely different than summer.

I also adjust my training depending on where I live. I adjust my bike training to the challenges of winters in Canada. So if a plan had me doing lots of Z2 bike, I wouldn't do it.
