On, the Swiss sporting goods brand of running shoes, has stopped working with TeamTBB, a group of 38 professional athletes, various country teams and a global network of certified coaches. After the departure of one of the coaches, Brett Sutton, and of top-athletes like Mary-Beth Ellis, Caroline Steffen, David Dellow and Daniela Halksworth, the Swiss brand decided to sponsor selected athletes like Ellis on an individual basis.
