Capitola/Soquel is a great place to live and train as a runner. Lots of tracks, lots of good year-round weather, no fluoride in the water, long runs at low tide on the wetsand, one of the best coaches around (Greg Brock), easy to get good food, a gym with a cold pool, low stress town, etc.
It is easy to thrive there. So frame it differently, Vessey is thriving there because she moved there. Anyone who says needs to do different is only projecting their own issues onto her.
