Upcoming trail races for the weekend of 4/20 & 4/21

With the weather giving us plenty of trail time lately I have been able to log many more trail miles than in months past. I'm really excited about racing on some of these trails as it has been several months since I have done a "local" trail event. I've decided on one so far (Horseshoe Lake in May!)and am quickly narrowing down my choices thereafter. If your not already running one of the big road races being held this weekend (Presidio 10),  then take a look at whats coming up this weekend to help fill up your race calendar.
