FOR MORE INFORMATION ON MP, PLEASE VISIT WWW.MICHAELPHELPS.COM.Reminder: The Weekly Wonders column is a celebration of age-group swimming, where new champions are made every day. Anyone can look up the top swims of the week. That’s not what we’re doing here. If we were only reporting on the week’s top swims we would feature the same handful of athletes every Wednesday. Instead, this is an opportunity to introduce the swimming community to athletes who have made great strides in the context of their own particular swimming worlds. By association, it also celebrates their coaches and their teams. The Weekly Wonders column, therefore, amounts to a pat on the back for a job well done, and hopefully encourages swimmers of all levels to continue to reach from within to get to that next level.
