I entered high school as a 100/200 runner (for freshman and sophomore year) and now I am a junior who decided to convert to 400/200 about a month into the season. Once the season is over, I plan to train year round for the 400/200. I have looked into training programs including Clyde Hart's training plan however, I can't find a training program that provides a training regiment for the summer. Does anybody have an elite training program that gives a full year training regiment?
Look for the 400 training plan thread on the first page of the High School forum. Many (like me) don't agree with Clyde Hart's training program.
Don't look at elites for year-round training schedules. They compete in different seasons than HS runners. But they do have base and sharpening phases that you could try to emulate. I'm not a 400m guy but from what I understand, most of them do over-distance endurance, weights, and top speed work in the off-season, then race-specific workouts at 400m pace in competition season. Check out speedendurance.com for some good 400m-oriented training advice.
Yep - ends to middle, with gym. Keep working on your 100 speed.
