The Stour Valley Path 100 (SVP100) runs one way from Newmarket Memorial Hall to Brantham Leisure Centre, 102 kilometres with no loop back to the start. The climbing looks modest, but most of the steep ramps sit beyond kilometre 60, and anyone who runs the early hours too freely pays for it there.
The longest climb of the day comes early: from kilometre 4 the course rises for nearly two kilometres, and by kilometre 10 it has already reached its high point at around 150 metres. From there it loses height steadily through Great Thurlow towards Clare. At kilometre 39, just past the second checkpoint, the first short ramp interrupts the run, and the course then rolls through Long Melford down into lower ground.
From kilometre 60 the character changes. Six short climbs follow by kilometre 87, none longer than a kilometre, each one handing its height straight back. They are steepest beyond Lamarsh at kilometre 73 and again right at the end at kilometre 87, where the pitches pass 15 percent.
The SVP100 is a point-to-point trail ultra. Six checkpoints divide the day, from Great Thurlow to Stratford St. Mary, and the last three are shared with the SVP50, which begins in Sudbury. After the final hill the course drops almost to sea level, and the remaining ten kilometres to the finish at the Brantham leisure centre are flat.

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.
The first half asks for restraint above all. On fresh legs the climb from kilometre 4 feels almost too easy, and the long gradual descent after it lifts your pace without asking. Keep it deliberately below what feels effortless: it is just over 18 kilometres to Great Thurlow and nearly 19 more to Clare, the longest gaps between two aid stops.
The SVP100 is decided between kilometres 60 and 88. No single ramp costs much, but they arrive with more than half the race in your legs, and each one forces a change of rhythm. March the steep pitches briskly rather than forcing them, then start running again the moment you top out. If you can still run the descents in between, you gain more time here than on any of the fresh kilometres earlier.
The trap closes at the very end. From kilometre 91 it is flat, nothing makes you walk any more, and anyone who overspent earlier is reduced to a shuffle exactly here. Keep the stop at Stratford St. Mary short and plan to run the last eight kilometres without a break.

Expect roughly eleven to sixteen hours as an age-group runner. For most of that time this is a calm aerobic effort, with a run of short spikes laid over it late, on tired legs. The climbing itself is not the problem; its timing is.
That is why the hills belong at the end of your long runs. Put short climbs of 300 to 500 metres into the final hours of a long run, several in a row, each with an easy run back down. Practise switching between strong hiking and running again at once, because that transition repeats constantly between kilometres 60 and 88 on race day.
Two long sessions on consecutive days prepare you for the closing stretch. The second day shows whether you can still hold an even running stride on level ground when your legs are tired. The flat kilometres before Brantham no longer ask for strength, only for clean form under fatigue, and this is the one way to rehearse it.
Over this many hours, fuelling carries the race. The checkpoints offer High5 products, bananas, pastries, sweets, water, cola and electrolyte. Use training to find out which of these your stomach still accepts after ten hours, and how much you want to carry yourself on the long sections to Clare. With the race held in August, put some of these runs on warm days so that you know how much you need to drink.
