Harwich Herring Run

The Harwich Herring Run is a scenic trail running and walking event scheduled for Sunday, April 26, 2026, on Cape Cod, Massachusetts. Organized by the Kiwanis Club of Lower Cape Cod & Eastham in collaboration with the Monomoy Key Club, the race serves as a community-driven fundraiser that highlights the natural beauty of the region during the annual herring migration. The event features a professionally timed 5K route designed to be a "fun family event," welcoming participants of all ages and athletic abilities to experience the unique coastal woodlands of Harwich.

Harwich is located on the southern side of Cape Cod, known for its extensive shoreline and freshwater ponds. Geographically, the race course circles the West Reservoir and crosses the historic Herring Run, where alewives migrate from the ocean to spawn in upstream ponds. The terrain consists of natural trails that can be uneven; participants are advised to exercise care while navigating the roots and sandy patches typical of the Cape’s coastal pine barrens. In late April, the maritime climate of Massachusetts is often brisk; average daytime temperatures reach 13°C (55°F), providing cool, oxygen-rich air ideal for trail running, though morning moisture from the Atlantic can make forest paths damp.

Logistical management for the 2026 run is handled through the Race Roster platform, with registration fees tiered for adults and youth (18 and under). The 9:00 AM start at 501 Depot Street provides easy access to the trail network, and the event emphasizes volunteer participation through the local Key Club. Following the race, the community atmosphere continues with a scheduled gathering at The Seal Pub in Harwich Center, allowing runners and walkers to celebrate their finish. Participants can track their impact through the event's fundraising leaderboards, contributing to the Kiwanis Club's various charitable initiatives across the Lower Cape.
