Bauble Bimble is a December race held at Ferry Meadows in Peterborough, located less than three miles from the city centre. Participants can select a 6-hour option starting at 9 am or a 4-hour option beginning at 11 am. Runners complete as many laps as desired before their allotted time expires. The structure is adaptable; runners may stop at 5K, progress to 10K, target a half or full marathon, or continue into ultra distances. Anyone departing Base Camp before 6:00:00 am will be permitted to complete one additional lap.
The course consists of a 5.3K forest lap on gravel footpaths and grass, classifying it as a multi-terrain event rather than a road race. A standard half marathon requires five laps, with the possibility to extend to six or seven laps on the day. A standard ultra involves nine laps, with the option to increase to twelve if time permits. The race is part of the Zig Zag Family series, and its accommodating lap format attracts many participants aiming for their first official 5K, 10K, half marathon, or full marathon. One participant achieved both their first marathon and a personal best marathon time at this event in Peterborough.
