Get your year started right with the SmartyPants Vitamins USMS Fitness Series and the Winter Fitness Challenge, a 30-minute swim that takes place between Feb. 15-28.

The event is perfect for anyone who has set a New Year's resolution to be more active, anyone who likes a challenge, or anyone who wants to support the USMS Swimming Saves Lives Foundation. The Winter Fitness Challenge can be done in any manner desired: straight through, as a member of a relay, or even with fins.

If you need help preparing for your swim, we have six-week training plans for all types of swimmers.
