RunThrough South Downs 50K Ultra Marathon
Experience the rolling majesty of the South Downs National Park in high summer. The RunThrough South Downs 50k Ultra is a looped spectacular starting from the heart of Queen Elizabeth Country Park.
While many South Downs ultras are point-to-point affairs ending at the coast, this event focuses on the lush, green and surprisingly steep trails around the Hampshire/Sussex border. It offers all the classic ingredients of the National Traill, chalk paths, ancient woodlands, and panoramic views, packaged into a highly accessible, well-marked race format perfect for those stepping up to the ultra distance.
Course
Starting from the event village at Queen Elizabeth Country Park (QECP), the 50km route heads out onto the iconic South Downs Way.
Unlike the flat coastal paths, this section of the Downs is characterised by punchy climbs and rolling chalk ridges. You will navigate a mix of wide grassy tracks, dense woodland trails, and open downland that offers views stretching across Hampshire and towards the Isle of Wight.
With approximately 1,490m (4,900ft) of elevation gain reported for the course, this is not a flat run. It is a test of stamina that rewards you with fast, flowing descents to recover between the climbs.
RunThrough are famous for their road races, but their trail series brings that same level of logistical slickness to the wild.
- Fully Marked: No navigation drills required. The course is heavily flagged, meaning you can focus on your running form rather than a map.
- Aid Stations: Expect regular, well-stocked checkpoints with water, energy drinks, and nutrition.
- The Atmosphere: The start/finish area at QECP is a buzzing event village with food, drink, and a supportive crowd, a great place for family to wait while you tackle the trails.
It is the perfect "bridge" race. If you are a road marathon runner looking to try your first ultra, the logistics here make it incredibly welcoming. For more details on the RunThrough South Downs 50K Ultra Marathon, including registration info, please visit the official race website.
