Isaac's Tea Trail Ultra. Backwards

A 37 mile loop follows Isaac's Tea Trail in reverse, starting and finishing in Allendale and passing via Ninebanks, Alston and Nenthead. The route lies within the North Pennines AONB and UNESCO Global Geopark, featuring open heather moors, peatlands, upland rivers, dales, hay meadows, woods and visible imprints of a mining past.

The event is offered as a solo ultra or as a relay for teams of up to three. The route is self navigating with permanent signage and marshals at key points. Organisers provide a downloadable map and a GPX file, an event tracker, well stocked checkpoints offering cold drinks, snacks and vegan options, free event photos and a branded event tea towel for each participant. The route includes approximately 4800 ft of total ascent and entrants have 12 hours to complete the course, equivalent to an average of about three miles per hour. Minimum age is 18 and registration is at Allendale Village Hall. A donation from each entry will support trail upkeep.
