Continue the Great Barrow Challenge with Day 4, a friendly multi-distance running event organised by Zig Zag Running at Suffolk Running Centre near Bury St Edmunds. Part of a series of ten consecutive days of running, the event offers distances from 5K and 10K to half marathon, marathon and ultra marathon. Whether entering for a single day or taking on the full series, participants can enjoy a rewarding challenge in the picturesque Suffolk countryside.
The day's route follows Back Quack, an approximately 10.7K circular course combining quiet country roads and rural trails. With around 52% of the route on road and 48% on trail, runners can expect varied surfaces and undulating terrain, including approximately 107 metres of climbing per circuit. Half marathon runners complete two laps, marathon participants tackle four, and ultra runners can extend their distance further. Those choosing the 5K follow a shorter out and back section.
With its welcoming atmosphere and flexible distance options, Day 4 provides another opportunity to explore Suffolk's attractive countryside while working towards individual running goals. A central aid station at Suffolk Running Centre offers refreshments and encouragement between circuits, while the repeated lap format allows participants to manage their pace and refuel as needed. Whether completing a shorter distance or pushing beyond marathon territory, runners can look forward to a supportive environment and a commemorative finisher's medal.
