Outdoors…
Get out hard the first 40-50m… use that speed down the backstretch (relaxing/dropping my arms a bit essentially trying not to use them) while making up a stagger or two carrying that speed through 250 and between 250m-280m with 120-150m lift start to dial it up for a strong finish.
Basically I break it into a 250/150 breakdown(where I am trying to go 29-30 for 250 and 18-19 for 150) just like in training. As the seaosn progresses I will be able to go out faster and hopefully finish stronger.
