JEFFERSON — Runners of all levels can join Hidden Valley Nature Center and Midcoast Conservancy at the second annual Spring Trail Running Training Series starting April 20 and run for six consecutive Wednesdays. Hosted at the center in Jefferson and sponsored by Trail Monster Running Club, runners will have the opportunity over the six-week session to run a scenic marked loop of either three- or six-mile trail.

Arrive between 4:30 and 6 p.m. Wednesday nights and run either loop either by yourself or with a group. This is an informal training series designed to be self-competitive, where runners will be timed and progress can be tracked each week on the course. Volunteers will be on hand to provide bibs, timing, water and encouragement.

The series will end May 25 a potluck cookout and prizes for all participants.
