The reporter at the SEC xc championship in 2022 asked Valby the same question. It is very noticeable, very odd, and unlike every other D1 athlete who takes time to recover from injury. With her it is a clear pattern. Ex.-comes back from injury late in outdoor 2022, gets beat soundly by Chelangat doubling at SEC, and within three weeks is stretching the whole field at nationals.
Ex. 2-comes back from injury again in xc 2022, and is suddenly demolishing course records, leading to the question by the reporter.
Ex. 3-comes back from injury again late in outdoor 2023, barely holds off the Alabama duo who were doubling off the 10000, then gets beat by Tuohy easily and hour after she won the regional 1500m. But fast forward two weeks, and she blows away the field at nationals sans Tuohy. Supposedly the heat explained it.
As I explained before, not buying it anymore.
