All cyclists must wear a helmet.  No ear buds allowed.  Your bicycle needs to be in safe, working condition, ie, front and back brakes need to work.  Stop by the Freewheeler Mobile Bike shop before the race if something unexpected comes up.  
The Dirty 30 course takes place on open roads, so all Michigan road laws apply to all cyclists.  Cyclists must obey all traffic signs, may not ride more than two abreast and should not cross the center line.  
The Dirty 30 course will be well marked with arrows at every turn.  Key intersections will be manned by volunteers and Ionia County police.  Cones and road paint will be used where necessary.  
Please position yourself in the starting chute based on your speed so we can have a safe event.  If you plan to average 20 mph or higher, move to the front.  If you plan to average less than 20 mph, move to the back.  I recently raced in a gravel race and was told that the leaders were initially averaging 25 mph  We don't want to slow these gals and guys down!  The start format will be a gun start with everyone's start time being the same. 
We will race rain or shine… or snow. In the event of a thunderstorm, tornado, or freak lake-effect blizzard, we will postpone the race until conditions improve. Find secure shelter if severe weather occurs before, during or after the event.  We will not be able to reschedule to a different date if weather causes the event to be cancelled.  Please bring rain gear and umbrellas if necessary.
