Suffolk 10k, Half Marathon, Marathon and Ultra – Endurancelife

The Suffolk Endurancelife event on 10 October 2026 is a coastal trail running festival held around Dunwich, Suffolk, offering 10K, half marathon, marathon and ultra distances on clearly waymarked routes. The event forms part of the Endurancelife Coastal Trail Runs programme and contributors earn points towards the 2026–27 Season Leaderboard, with organisers emphasising environmentally responsible use of land managed by Natural England, the RSPB and the National Trust. Participants are encouraged to complete online check-in ahead of the day to update emergency contacts and watch a mandatory safety briefing, with route maps and a participant manual provided on the event pages.

Entries include refund and transfer flexibility, on-course electronic timing and finishers medals, plus event village amenities and on-site food and drink. The event offers a range of entry categories and discounts for multi-event bookings and groups, and several optional add-ons such as a safety kit, parking permit and short massages. Post-event social options are suggested locally (The Ship Inn is listed as a nearby gathering point) and the organiser maintains a dedicated Times page and FAQs for race-day details such as start schedules.
