I don't especially buy it. I mean, you want some tune-up races before the key race and she's running short on time for tune-up marathons.
That said, she had been doing a lot of marathons. Getting some kind of break probably would have been a good thing. However, the extent of this “break” seems extreme. Also, any time a runner spends on crutches doesn't seem like any kind of blessing.
More than anything, I think it's trying to put a positive spin on a negative situation.
