)I wouldn't have her do any 400 meter specific training this summer. I would have her work on pure speed by running 30s, 40s, 50s. I'd have her do drills to improve her form, and work on her explosiveness as well. Hill running focusing on form and turnover but not worrying about time will be helpful. Non running activities to improve general fitness should always be undertaken.
Her 200 time seems poor relative to her 100 time. I don't have any girl who runs 13 flat but many that have faster 200 times.(
I agree in general.
Athletes of all types need an aerobic base. Sprint training is more like distance running than many think. In the off-season the first thing I would have her do is run 2-6 X 200 @ 80% of her top speed with 30 seconds recovery. She will not be able to do many of these at first. Do not force her to!!! All of this should be fun! (2 X 200 may be enough the first few weeks.
The next day have her jog a mile for recovery.)
Read articles on sprinting. There are tons of them on the internet. If you can, find a successful sprint coach and have her work on relaxation, acceleration, and classical running form. She should have something to work on every time she runs. "The mind makes you run fast"- Dr. Ernie Gregoire, former Olympic Assistant Coach.
Rope skipping, plyometrics, and fast dynamic running drills will also help. But with anything new START EASY. Lots of easy recovery runs are also recommended. Larry Myricks ran 3-5 milers during the off-season and ran 20.03 in the 200 and Long Jumped 28'8". It is a myth to say it takes away your speed. One needs 36-48 hours to recover from hard training (sprint training is hard on the body!).
"So that is the time to do some jogging to recover" - Larry Myricks 3 X Olympian. (In our 8th grader's case, 1-3 miles may be enough for the recovery jog the day after sprint training. It is important!) Bike riding is also good.
Never over do anything! What you learn on LRC is only scratching the surface on what one needs to know about speed.
