TrevorS, EFE stands for easy-fast-easy and the reverse for FEF.
John, that’s what I meant regarding working from both ends. The latter point on developing maximum speed as much as possible is also true and especially for women. As Charlie says in his book “The key to the longer sprints (200-400 m) is the speed reserve, especially in races such as the women’s 400 m. There are few women, who are good in the 400 m at the world level and not also good in the 100-m sprint.” In gofast’s model though -which I am sure has been quite successful- attention should be paid on the 4-day weeks’ schedule (e.g., working on a 2+1-week plan). Perhaps he could comment on that and how it may fluctuate per phase.
