Rat Race 100 Edinburgh

The Rat Race 100 Edinburgh is a fully supported, waymarked ultramarathon and trek covering 100 miles (160km) with a 48 hour completion window. The event is listed as a mass participation run/trek and runs as one part of a three-event trilogy where each edition starts where the previous one finished; completing all three earns the Trilogy Finisher buckle.

The series has no qualifying times and is set around a walker-friendly 2.5 mph moving pace. Routes are marked with bright orange arrows and staffed at key points. Organisers provide multiple staffed Pit Stops with water, juice, sweet and salty snacks, fruit, toilets and medical cover, plus enhanced Pit Stops with hot food options at some locations. Medical provision is delivered by a professional event medic team including paramedics and doctors operating from vehicles and an ambulance.

Logistics include bag transport for up to five bags with specified size and weight limits, designated sleep stations at selected Pit Stops with an increased bag allowance for those who plan to rest, and a sweeper service for participants who withdraw. There are enforced cut-offs after Pit Stop 6 aligned with the 2.5 mph moving pace; organisers may implement additional cut-offs in exceptional circumstances. Registration and tracker collection take place in Edinburgh city centre before the event. The organiser reports a 69 percent completion rate from its inaugural 100 mile edition.
