I support and have ran with my local running store, Fleet Feet in Gaithersburg, for many years now.
They are holding their yearly free triathlon series, including:
2/20/2012 - Bike. Matt McGoey from All American Bikes in Damascus will help you with proper form, bike technique, how to change a bike tire, and more...
3/19/2012 - Swim. Janet Witkowski, from JW Fitness and Wellness Coaching, will help with form, technique and tips for the swim.
4/23/2012 - Overall preparation and transitions. Lloyd Henry from On Point Fitness will speak to you about your overall plan and changes, and how to prevent panic.
