Klosterhalfen looks great right now, and Shelby would have had a tough time staying with her. I don't think she can beat her right now. I hope she doesn't overtrain/race before the Worlds because I feel she can challenge the best of the rest. She is very strong.
Konstanze's main races this indoor season are European Champs in Glasgow. Not sure if Hassan is racing (doesn't look like), but Muir is. It should be good racing.
