Run report: St Just to St Ives, the long way through the bogs

On 3 July I ran from St Just to St Ives along the coast path: 30 kilometres, 882 recorded metres of climb, five hours and one minute elapsed. The recording from that run now powers two route pages on this site. This is what the watch saw, and what it couldn't.

This was never meant to be a fresh-legs showpiece. It was the final long run of a Lakeland 50 training block — the penultimate run before taper — done deliberately on heavy legs, in full Lakeland mandatory kit, carrying three litres of fluid. The forecast said hot. The coast said hotter, and windless with it.

St Just to Pendeen Watch — 7.3 km, 55 minutes

The mining coast moves fast by far-west standards: mine tracks past Botallack's engine houses, runnable gravel, the lighthouse arriving almost on schedule. The pack sat heavy but the ground was generous, and for the first hour the heat was weather rather than the story. That changed.

Pendeen to the Tinners Arms — 12 km, climbing towards 2 h 58 total

Gurnard's Head came up at 2 h 13. This middle third is where the route stops being a running route in any ordinary sense: rock up through the grass, pace becoming a rumour. The real enemy was the air. On the tight, hedge-crowded paths the vegetation seems to bank the heat and give it back, and the far west turned into a sauna with a sea view. The saving grace: even after several heatwaves the valley streams were still running, and I dunked head and cap at every single one.

I reached the Tinners Arms in Zennor at 2 h 58 and stopped for 26 minutes. The recording is honest about this and so am I: shade, a long drink, a sit-down in a cool room with eleven kilometres of boulders still owed. In that heat it was the correct decision, made easily. The Arc of Attrition crosses this ground in January darkness, where no such mercy is on offer.

Zennor to Porthmeor — 10.7 km, 1 h 37 moving

The famous half: the boulder field below Zennor Head, then cove after cove to Clodgy Point before St Ives finally lets you in at Porthmeor. Moving pace here says everything — this is ground you place feet on, not ground you run, and precise feet were exactly what six weeks of Lakeland training had used up. July adds its own obstacle: this half belongs to the day-walkers out of St Ives, arriving in cheerful single file — a striking proportion of them American — and on ground where overtaking means rock-hopping, patience becomes part of the discipline. St Ives arrived loud and crowded, the way St Ives in July does, and Porthmeor stopped the watch at 5 h 01.

What it changed on this site

The run's track replaced the desk-researched lines for St Just to St Ives and Zennor to St Ives, which both now carry field-checked status. Pleasingly, the mapped Zennor line we published beforehand agreed with the recording within five per cent — the desk research held. And anyone eyeing the Arc of Attrition should note these kilometres arrive in that race at night, in January.
