Rat Race 100 Edinburgh

The Rat Race 100 Edinburgh to Glamis is a mass participation 100 mile (160 km) ultramarathon held over a 48 hour duration on 24–26 July 2027. The event is presented as part of a three‑event trilogy in which each edition continues from the previous finish; completing all three events earns a Trilogy Finisher buckle.

Entry requires no qualifying time and the route is designed to allow walkers with a 2.5 mph moving pace to complete the course. The route is fully waymarked and fully supported by event staff. Organisers provide multiple staffed Pit Stops offering water, juice, sweet and salty snacks, fruit, toilets and an on‑site medical team; some Pit Stops offer enhanced hot food and additional provisions. A professional medical delivery service provides on‑site paramedics, doctors and ambulance cover, and the event is subject to independent safety and risk audits.

Logistics include tracker collection at Friday registration in Edinburgh city centre and bag transport from start to finish. The event will transport up to five drop bags with specified size and weight limits, a larger finish bag allowance, and optional sleep station allowances at selected Pit Stops. A sweeper service can transport participants who withdraw. Cut offs apply from Pit Stop 6 onwards and are aligned with the published completion pace; earlier enforcement may occur only in exceptional circumstances.

Participants must be over 18 on the day of registration. Results are not presented in finishing order in keeping with the event’s non‑competitive ethos. Visit the organization's website for the most recent information.
