On the Long Marathon, Race The Tide takes you from Mothecombe across the private Flete Estate to the South West Coast Path, over the causeway at Burgh Island and home through South Hams woods and fields. The name says marathon, the distance is almost 29 miles, and the preparation has to answer a day of short, steep ramps and the descents between them.
The setting is the Flete Estate near Mothecombe in South Devon, privately owned land whose footpaths the course uses alongside bridle paths, fields, woodland and the South West Coast Path. The circuit heads out to Burgh Island, crosses the causeway and carries on to Wonwell Beach. From there, coast path, woods and the South Hams hills make up the way back to Mothecombe.
You rarely get much above 100 metres, yet the route keeps dropping almost to sea level. The first two kilometres alone lose around 50 metres. Three climbs follow between km 5 and km 13, the steepest of them starting at km 12 and reaching the highest ground of the circuit in a little over 600 metres. Two more, at km 18 and km 21, lead to the long descent that bottoms out just above the sea around km 24.
The second half climbs less often and harder: two pitches at km 28 and km 36, each under half a kilometre, average more than twelve percent. After a rolling stretch the course drops from km 43 nearly to sea level one last time, and the final climb only delivers you shortly before the finish.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
Only about a fifth of this course is flat, and the rest splits almost evenly between up and down. Kilometre splits mean little here, so run to effort. Walk the steep ramps from the very start, and treat the descent after the start as a warm-up, not as time in the bank.
The biggest trap is the first 13 km. Three climbs come close together on fresh legs, and running them gets you to the top of the circuit feeling fine. The bill arrives on the steepest ground later, when walking stops being a choice and becomes all you have left.
The race is decided beyond the marathon mark. At km 42 you have a full marathon in your legs and still more than four kilometres to go: a drop of around 80 metres that punishes tired quads, then the closing climb. Keep something back for this stretch, because it can cost more time than any ramp before it.

Age-group runners should expect roughly five to seven and a half hours. The effort stays aerobic but keeps being interrupted: every ramp spikes your heart rate, and while the descents give your lungs a break, they give your legs none.
The key section comes late, so the hard part of your long runs belongs late too. Make them hilly and put the steepest repeats in the final third instead of ticking them off fresh. A hilly three to four hours tells you more about your race effort than any flat run of the same length. Practise a brisk, short-stepped power hike on steep slopes while you are there, because on the second-half pitches it will serve you better than any speed session on the track.
Nearly as much of the course runs down as up, and that is what settles the last kilometres. Build strength in your quads and run downhill on purpose towards the end of longer sessions, so a descent after hours on your feet is not something your legs meet for the first time on race day.
The ground switches between coast path, bridle path, field and woodland, so your long sessions should happen on similarly mixed terrain, not tarmac. With the race on 22 May, the longest runs fall in April: use them to test shoes and fuelling over many hours on your feet.
