There is a 10K is starting at 8 a.m. in Lancaster this year. This will result in intermittent closures on Walden Ave at Central and the complete closure of Harris Hill/Central from Pleasant View to Broadway beginning at 8 a.m. and continuing after the 9 a.m. ride start time. Those coming from the North will have to take alternate routes. It might be best to take William Street from Transit Rd or Bowen Rd, then turn onto Lake Ave going north, then access the park via Waltham, Como Park Blvd or Quincy. Park by the softball diamonds on the right. The posted routes for the 18 ans 22 mile ride options have been modified at the end to avoid congestion on Erie St where the parade starts. Modified cue sheets will be available from the ride leader. The parade starts at noon.
