This free running event welcomes kids ages 3-14 from the Greater Lehigh Valley on May 16 at Lehigh Parkway in Allentown, offering distances from 1/8 mile for the littlest runners up to 2 miles for teens, with wave starts for the 3-6 age group and refreshments provided to all participants. You'll need to register online before the Wednesday deadline, and keep in mind the race depends on volunteer support—if not enough volunteers sign up by registration close, the event won't happen. The race goes on in any weather, with cancellation updates posted by 7:30 AM on the LVRR website, Facebook, and via email if needed.
