New Hampshire’s fun all-ages 5K featuring trails, woods, hills, and over 20 obstacles — a challenging course that supports local and international service projects.
On-course refreshments and portable toilets available; water and snacks provided at aid stations.
Pacemakers will be present with target times displayed on the Race Day schedule (Renntag) by start wave; look for Pacer flag markers during the course.
Monthly averages based on historical data (2000–present).
Wear whatever you feel comfortable in when running, climbing and crawling! We also suggest wearing gloves, as several of the obstacles can be rough on the hands.
30 minutes before your assigned start time should be sufficient for traffic, parking and sign in. The first heat for competitive runners starts at 8:30 AM. Is weather an issue? Thunder Run runs rain or shine, hot or cold. That’s part of the challenge, and part of the fun! Cancellation? If, for some reason (an Act of God?) Thunder Run is canceled, emails will go out, and announcements will be made on this site, and via social media accounts. "Amenities" Parking is free. There will be refreshments and portable toilets available, as well as an area for changing clothes, if desired. Every runner gets a medal and a Thunder Run t-shirt. Can we bring friends and family? Sure! Spectators are allowed at no extra charge. Feel free to bring your own cheering section! What should I wear? Wear whatever you feel comfortable in when running, climbing and crawling! We also suggest wearing gloves, as several of the obstacles can be rough on the hands.
