Rock Springs Run State Reserve is a gorgeous venue for local events. The venue is known to many as the location of the 2015 BattleFrog Championship race. As beautiful as the venue is, the trails are sugar sand providing a new challenge to runners from anywhere but Florida. Saturday morning was cool and cloudy, a welcome relief from the recent eighty degree days. There was a lot of excitement among racers because Bonefrog Challenge was the start of the 2017 season for many.
