The 3rd annual Level Pebble Triathlon takes place in early August in Flat Rock, MI (a suburb south of Detroit), and is the perfect race for anyone from beginners who want to give it a "tri" to veterans who want to test their fitness in a smaller venue. The swim takes place in the 6-lane competetive pool at the Flat Rock Recreation Center. The bike follows a portion of the Downriver Linked Greenways (DLG) non-motorized path as well as lightly traveled roads in Flat Rock and Gibraltar. The run is almost completely done on a different section of the DLG away from bike traffic. 
This friendly event is supported by local businesses who have generously donated prizes as well as post race food.
