Race Day Weather

Average Temperature11°C / 52°F
Humidity89%
Wind33.3 km/h
Rain Chance68%
Typical ConditionsA raw, exposed start on the edge of Bodmin Moor in early November - one of the wettest months in Cornwall. Expect around 8-9C (47-48F) at the 09:00 gun, climbing only to the low teens, with high humidity near 88% and a real chance of rain, mist or wind sweeping across the open moor.

What to Prepare: Dress for single-digit Celsius with a light waterproof layer you can carry - the weather on the moor changes fast and the exposed sections offer little shelter. This is an all-road course, so road shoes are right; save your legs for the brutal climb to Foredown between miles 24 and 25 and run the early hills by effort, not pace.

Course Analysis

Course Overview: Cornwall's Only All-Road Marathon Across Bodmin Moor

The Cornish Marathon starts and finishes at the Millennium Centre in Pensilva, a small village on the south-eastern edge of Bodmin Moor. Held annually in early November (next edition Sunday 1 November 2026), it is billed as Cornwall's only all-road marathon — 100% tarmac the whole way, but run on narrow, open, exposed moorland lanes rather than closed city streets.

This is a small, character-rich club race, first run in 1984 and organised by East Cornwall Harriers since 1987, with roughly 366 finishers in the 2024 40th-anniversary edition and a 2026 field capped at 475 places. Do not mistake "all-road" for "flat": total cumulative ascent runs roughly 600-665 m (around 2,200 ft) of relentless rolling climb, with no flat to speak of. The defining feature is the timing of that climbing — about a quarter of the whole ascent piles into the last five miles. statathon estimates a 3:30 flat-course runner loses around 13 minutes here to the terrain. This is a race won by patience, not by early ambition.

Start to Half: Pensilva Laps, Golitha Falls and the Climb to Jamaica Inn

Runners begin with two gentle laps of the lanes around Pensilva village — a supporter-lined, relatively easy introduction (the start was moved here from Rilla Mill, replacing an old steady three-mile opening climb). From there the route climbs out toward Crow's Nest and onto the moor via Tokenbury Corner and Darite.

Crucially, the first roughly eight miles trend net downhill, with longer descents than ascents, dropping to the course's lowest point at Golitha Falls in the Draynes Valley beside the River Fowey. One caution: reports note flooding and standing water before Golitha Falls that can soak your feet for the rest of the day. From the falls the course then climbs substantially onto the high open moor, running past Colliford Lake (Cornwall's largest), with views toward Brown Willy and Rough Tor, before topping out at its highest point at the Jamaica Inn near Bolventor. Resist banking time on that early downhill — you will pay for it later.

Half to Finish: The Draynes Valley Trap and the Foredown Sting

From the Jamaica Inn high point, the course turns back and descends through the Draynes / Fowey Valley — roughly four to five miles of gentle downhill and flat alongside the River Fowey, passing Golitha Falls again. Legs settle into an easy valley rhythm here, and that is precisely the danger.

This is the trap. Just as you have adapted to the relaxed valley running, the course turns vicious. From around mile 21 the hills resume, with over 200 m of climbing crammed into the final five miles — about a quarter of the entire race's ascent — which one finisher called "the hardest road five miles." The single most-cited sting is the sharp climb to Foredown between miles 24 and 25, right when there is nothing left in the legs. The route returns toward Pensilva through Darite and Crow's Nest, and the only relief is a welcome downhill final half-mile back into the village. Several runners name the easy Draynes Valley as the toughest part mentally — not because it is steep, but because it seduces you into thinking the worst is over.

Race Strategy: Save the Legs for Miles 21 to 25

The whole race is built around one decision: hold back on the first half. The gentle Pensilva laps and the net-downhill run to Golitha Falls tempt you to bank time, and the easy four-to-five-mile valley descent after Jamaica Inn reinforces the illusion. Run those sections within yourself; the race only truly begins at mile 21, where over 200 m of climbing and the Foredown ascent (miles 24-25) decide your finish.

On gear and conditions: the high Bodmin Moor sections are fully exposed to wind, cold and rain in early November, so plan layers you can manage on an open course. Note also the 6.5-hour time limit is enforced via moving cut-off points around the course, not just at the finish line — you must stay ahead of a rolling cut-off, so banking a buffer early matters for slower runners. Entry is online via SiEntries only, with no race-day entries and a capped field that sells out, so enter early; the 2026 entry fee is £41 affiliated / £43 non-affiliated. The start point is the Millennium Centre, Pensilva, PL14 5NF, with Liskeard the nearest mainline rail station; confirm the exact start time on the official site, as sources differ.

Frequently Asked Questions

What is the Cornish Marathon route?

The Cornish Marathon starts and finishes at Millennium House in Pensilva, near Liskeard, and runs a single scenic out-and-back loop on public roads across the edge of Bodmin Moor. The route heads up the Draynes Valley, through the 'Poldark' country of the moor past King Arthur's legendary Dozmary Pool and Du Maurier's Jamaica Inn at Bolventor, then returns along the Fowey Valley. It is billed as Cornwall's only all-road marathon.

Is the Cornish Marathon flat? How hard is it?

It is far from flat - it is relentlessly hilly and widely rated one of the toughest road marathons in the UK, nicknamed the Beast of Cornwall. The course rolls over Cornish lanes for the whole distance and stings you with a savage climb to Foredown between miles 24 and 25, just when your legs are gone. Most runners finish well outside their flat-course time. Plan a conservative effort with our pace calculator and study the hills with our elevation profile tool.

How much climbing does the Cornish Marathon have?

The course packs in roughly 640m (about 2,200ft) of total ascent, spread across constant rolling Cornish hills rather than one mountain. Independent sources put the climb in the 635-670m range. The sting in the tail is the steep ascent to Foredown in the final two miles, which makes a hard day even harder. Budget several minutes slower than a flat marathon when you set a goal time.

What surface is the Cornish Marathon and what shoes should I wear?

The Cornish Marathon is run entirely on tarmac public roads and lanes - it is Cornwall's only all-road marathon, not a trail or off-road event. Normal road shoes are the right choice; you do not need trail shoes. Because it is so hilly, many runners pick a slightly more cushioned road shoe to protect the legs on the long descents and the late climb to Foredown.

How do I enter the Cornish Marathon 2026?

Entry is open to the public online through SiEntries, with no ballot. The field is capped at 475 runners and sells out fast, so enter early. Fees are around 43 GBP unaffiliated / 41 GBP for ARC or UK Athletics affiliated club runners. Entries for 2026 open on 9 May and close on 23 October 2026, or sooner if the event fills.

What time does the Cornish Marathon start and what is the cut-off?

The 2026 race starts at 09:00 from Millennium House in Pensilva on Sunday 1 November 2026 (organisers have flagged a move to a 9am start). There is a 6.5-hour cut-off, with intermediate cut-off points around the course; marshals stand down after this time. The day also includes a Fun Run alongside the marathon.

Is the Cornish Marathon a Boston Qualifier?

In principle, yes. Unlike a trail race, the Cornish Marathon is an all-road course measured by the Association of UK Course Measurers (measurement renewed in 2023), so a finish time can in principle count toward a Boston qualifying (BQ) or London Good For Age (GFA) entry. The catch is the difficulty: with roughly 640m of climbing this is one of the hardest places in Britain to actually run a qualifying time. Check the standards with our Good For Age tool, and if a fast time is the only goal, a flatter race is the smarter pick.

How do I get to the Cornish Marathon, and where do I stay?

Pensilva sits in rural east Cornwall on the edge of Bodmin Moor, a few miles from Liskeard. The village has no station, so most runners drive; the nearest mainline railway is Liskeard (on the London Paddington-Penzance line), with Plymouth the closest larger hub. Accommodation is limited around Pensilva itself, so many runners stay in Liskeard, Bodmin or Plymouth and travel in on race morning.
