A flat former railway line, but a genuinely new event
The Tarka Trail Railway Marathon runs an out-and-back route along North Devon’s Tarka Trail, a traffic-free path built on a former railway line beside the River Taw estuary and through woodland, with only the opening and closing kilometre crossing farm fields at Woolmer’s Farm. On paper this looks like a fast, flat course, and the organiser’s own route file confirms it: a real elevation range of only 5 to 25 metres across the full distance. But this appears to be a genuinely new event as of its 2026 edition, meaning independent runner-experience evidence is still thin. Similar flat rail-trail marathons elsewhere can run fast but also feel exposed and mentally repetitive across an out-and-back structure, and that pattern should be treated as a general caution rather than an established fact about Tarka specifically until direct runner reports become available. This is a race best suited to runners drawn to North Devon’s coast and the Tarka Trail’s own literary connection to Henry Williamson’s novel, who are comfortable with an out-and-back format and are happy to be among the race’s earliest participants rather than relying on an established track record.
History
The Tarka Trail Railway Races Marathon is organised by Relish Running, based at Woolmer’s Farm near Barnstaple, Devon, and run alongside 50km, half marathon/25km, 10km and Colourburst family race options on the same day. This appears to be a new event as of the 2026 edition, which took place on 28 June 2026, meaning independent runner-experience evidence is genuinely limited. No confirmed founding year, finisher count, or post-2026 runner reports have been sourced.
The course
The Tarka Trail Railway Marathon runs an out-and-back route along the Tarka Trail, a traffic-free shared-use path built on a former railway line from Barnstaple, alongside the River Taw estuary and through woodland. The opening and closing kilometre crosses farm fields at Woolmer’s Farm, with the rest of the route on predominantly smooth, flat tarmac. The organiser’s own route file confirms this: elevation ranges only 5 to 25 metres across the entire course, genuinely flat. This should read as a fast-looking course on paper, but similar flat rail-trail marathons elsewhere can be fast while also feeling exposed and mentally repetitive; that should not be stated as established fact for Tarka specifically without direct runner evidence, given how new the event is. Because the trail is a shared-use path, runners should expect other trail users unless the organiser confirms the route is closed or specifically managed for the race.

Pacers
Not confirmed. No pacer programme has been sourced for this race, particularly given this is a new event. Given the flat, out-and-back format, runners chasing a specific target time can use the halfway turnaround point as a natural pacing check against their outbound split.
What to wear
No confirmed race-day temperature average exists for this race. The confirmed 2026 date was late June, suggesting an early-summer race, though the exposed nature of a former railway-line trail beside an estuary means weather conditions can still vary meaningfully from a sheltered inland course.
Entry
Entry is direct through Relish Running, with no ballot found. Whether a future date has been published should be verified directly against the live official page, given the confirmed 2026 event took place on 28 June and had already passed by the time this guide was researched. Specific entry pricing, closing date, refund policy and any elite or Good for Age entry route have not been sourced.
Fast Runner / GFA Standards
Not confirmed. No Good for Age, elite or fast-runner entry information has been sourced for this race.
Race Weekend
Expo
Not confirmed. No expo information has been sourced for this race; many UK races of this scale use posted numbers or race-day collection instead. Check the live official Relish Running page closer to any confirmed future race date for current-year registration and collection details.
Race Morning
The race starts and finishes at Woolmer’s Farm, near Barnstaple, Devon, on the Tarka Trail route. Because the event uses a shared-use path, runners should expect other trail users unless the organiser confirms the route is closed or specifically managed for race day. No confirmed race-day parking, public-transport advice, or bag-drop arrangement has been sourced for this guide.
Nutrition on Course
Not confirmed. No confirmed aid-station locations have been sourced for this race. Verify exact aid-station spacing from the current race guide once a future edition date is confirmed.
Spectating
No official spectator points along the course have been sourced. Given the rural, shared-path setting of the Tarka Trail, spectator density away from Woolmer’s Farm itself is likely low, though this has not been directly confirmed by runner reports given how new the event is.
Itinerary:Base at Woolmer’s Farm near Barnstaple to see runners at the start and finish. No confirmed mid-course spectator route along the Tarka Trail has been sourced.
Post-Race Food

Book accommodation once entry is confirmed and re-check race-weekend prices closer to the date, consistent with standard practice for city-adjacent races, though North Devon’s genuine holiday-season popularity in summer months means booking earlier than for a purely off-peak rural event is sensible.
