20k Run South Cambridgeshire: Scenic Wicken Fen Loop

Route Overview & Local Insights

Clocking in at a substantial 19km, this flat and fast loop through South Cambridgeshire is a dream for runners looking to build endurance without the quad-heavy toll of significant hills. With a 60% paved surface, you’ll find a reliable rhythm as you traverse the expansive wetlands of Wicken Fen and the tranquil reaches of Adventures Fen. The terrain is exceptionally level, featuring only 11 meters of total ascent, making it an ideal long run for those targeting a half marathon PB. Expect a refreshing mix of well-maintained paths and rural trails that offer sweeping, unobstructed views across the iconic East Anglian skyline.

Running through Wicken Fen is like stepping back into a prehistoric landscape; as the National Trust's oldest nature reserve, it preserves an ecosystem that once covered much of East Anglia. Local runners often share the trails with Konik ponies and Highland cattle, which graze freely to maintain the vibrant biodiversity of the marshlands. As you pass through the historic village of Reach—famous for the ancient Reach Lychgate and the terminus of the Devil's Dyke—you are tracing the edges of Anglo-Saxon history. This route perfectly captures the haunting beauty of the "big sky" country, offering a peaceful, immersive escape into one of England's most significant ecological gems.
