RUNNING FROM........

Just registered for my first run.I've been wanting to do one for awhile.I registered for the Montvale 5&10 miler put on by Josh and Gina Gilbert of Mountain Junkies.com.They put on a great event I've been wanting to show my support for awhile. Maybe I should have passed out water!I've been hitting the treadmill after my weight training for a few weeks now.So ill hit some trails a few times this week.Without my Bike!Do I need to wear a helmet?:°
