Rich,
It was great to have this conversation. As a parent, you are of course the ultimate expert as you are managing expectations on a 24 hour 7 day a week basis. It sounds like you have thought about the same issues.
I don’t know what Derek’s SPP looks like, but I’d imagine that it has a fairly strong speed focus.
It will be interesting to see what she can do with her 100m and 200m times this year, and what kind of impact it has on results in longer races.
