Get the Great Barrow Challenge underway with Day 1, a welcoming multi-distance running event organised by Zig Zag Running at Suffolk Running Centre near Bury St Edmunds. As the opening event in a series of ten consecutive days of running, participants can choose from 5K, 10K, half marathon, marathon and ultra marathon distances. Whether entering a single day or tackling the entire series, runners can enjoy a friendly countryside challenge at their own pace.
The opening day's route follows Denham Flats, a predominantly flat out and back course along quiet Suffolk country lanes. Each full circuit covers approximately 10.4K, with just 22 metres of climbing, making this one of the gentlest routes in the Great Barrow Challenge series. Runners head out towards the turnaround point before retracing their steps, enjoying a very gradual rise on the outward leg and a slight downhill return. Longer-distance participants complete repeated circuits, while 5K runners use a shorter turnaround point.
With its supportive atmosphere and flexible distance options, Day 1 provides an enjoyable introduction to the Great Barrow Challenge. A central aid station at Suffolk Running Centre allows runners to refuel between circuits, while the repeated route creates plenty of opportunities for encouragement from fellow participants. Whether taking on a shorter distance or beginning an ambitious multi-day endurance challenge, runners can look forward to a rewarding finish and a commemorative medal.
