Continue the Great Barrow Challenge with Day 3, a welcoming multi-distance running event organised by Zig Zag Running at Suffolk Running Centre near Bury St Edmunds. Forming part of a series of ten consecutive days of running, this event offers distances from 5K and 10K to half marathon, marathon and ultra marathon. Whether entering for a single day or tackling the full series, runners can enjoy a rewarding challenge through the Suffolk countryside.

The day's route follows Quackers, 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, the course offers varied running surfaces and undulating terrain, including approximately 109 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 friendly atmosphere and flexible distance options, Day 3 offers another opportunity to explore Suffolk's attractive countryside while working towards individual running goals. A central aid station at Suffolk Running Centre provides 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 taking on an ultra marathon challenge, runners can look forward to a welcoming finish and a commemorative medal.
