Montane Lakeland 100

The Race

The Montane Lakeland 100 — officially titled the "Ultra Tour of the Lake District" — is the UK's most demanding trail ultra. A completely circular 100-mile route that encompasses the entire Lake District, it runs almost entirely on public bridleways and footpaths and deliberately avoids the popular summits and tourist honeypots.

Starting at 6:00pm on Friday evening from John Ruskin School in Coniston, the route heads south before sweeping clockwise through some of the most remote and spectacular terrain in England: the Dunnerdale Fells, Eskdale, Wasdale, Ennerdale, Buttermere, Keswick, Matterdale, Ullswater, Haweswater, Kentmere, Ambleside, and Elterwater — before returning to Coniston. The cutoff is Sunday at 10:00am, giving runners 40 hours to complete the course.

The 40-50% DNF rate is not incidental — it reflects the true difficulty of the event. Many experienced ultrarunners with strong road or flat-trail CVs have found the Lakeland 100 humbling. Technical terrain, unpredictable Lake District weather, mandatory night running, and relentless navigation demands combine to make this one of the most honest tests in British ultra running.

The Route

The course is split into four sections, each with an organised recce day available in the lead-up to race weekend. Understanding what comes between each checkpoint is as important as your fitness — the navigation on this race is the difference between finishing and not.

Section 1 — Coniston to Buttermere

The race begins with a gentle but deceptive start south from Coniston, through the Dunnerdale Fells and down into Eskdale. This section feels manageable on fresh legs but the terrain underfoot — wet grass, bog and rocky paths — begins to slow your pace more than expected. From Eskdale the route climbs over into Wasdale, one of the most remote valleys in the Lake District. By the time you reach Buttermere you have already covered significant distance in the dark. Many runners arrive at Buttermere in the early hours having barely slept — this is the point where the race separates those who have prepared for night running from those who haven't.

Section 2 — Buttermere to Dalemain (Halfway)

From Buttermere the route climbs towards Keswick, passing through Braithwaite and Threlkeld before heading south through Matterdale and arriving at Dalemain Estate near Ullswater — the halfway point and the start of the Lakeland 50. Most 100 runners arrive at Dalemain somewhere between Saturday mid-morning and Saturday afternoon. This is where the Lakeland 50 runners join the course (heading in the same direction) and the checkpoints become busier. Reaching Dalemain in good shape — physically and mentally — is the primary goal of the first half.

Section 3 — Dalemain to Ambleside

The second half of the race covers the same terrain as the Lakeland 50. From Dalemain the route heads through Howtown, around Ullswater, and into the remote valley systems of Haweswater, Long Sleddale and Kentmere. This section contains some of the most technical and draining terrain on the course — arriving into it after 50+ miles on a second night of running. Ambleside, at roughly mile 75-80, is a major psychological landmark.

Section 4 — Ambleside to Coniston (Finish)

The final section from Ambleside passes through Elterwater and begins the long descent toward Coniston. On paper it's the shortest section. In practice, arriving at Ambleside after 75+ miles and a second night of running means it feels anything but short. The finish at John Ruskin School in Coniston is one of British ultra running's great moments — but you have to earn it.

Navigation

The Lakeland 100 is not waymarked. You navigate using the Harvey 1:40,000 race map, the official road book (a detailed route description), and your compass. GPS tracks are available and most runners carry a GPS device — but it supplements rather than replaces map-and-compass skill. Batteries die. Devices fail. You must be able to navigate independently in the dark.

The road book describes the route in detail, but reading it in the dark, in the rain, after 30 hours of running, while your pacer shines a torch over your shoulder, is a skill unto itself. Practise navigating with the road book on all your recce runs. Know what a wrong turn costs you in terms of time and morale at 3am in Eskdale.

Mandatory Kit

The kit list is checked at registration and non-negotiable. Carrying it all adds real weight to your pack — train with a loaded pack on long runs so race day isn't the first time you discover the chafing.

• Waterproof jacket and trousers (fully waterproof, taped seams)
• Hooded jacket
• Emergency spare base layers in a sealed bag (long sleeve top and bottoms)
• Hat and gloves
• Map (race map supplied at registration) and compass
• Road book (supplied at registration)
• Head torch + spare batteries or second head torch
• Whistle
• First aid kit
• Emergency rations — 2 chocolate bars, separately sealed from eating food
• Survival blanket, bag or duvet
• Mobile phone, fully charged
• Solid plastic cup (for hot drinks at checkpoints)
• Water bottle or soft flask
• Eating utensil (FOON or spork)
• £1 coin (checkpoint toll — a race tradition)

Training & Preparation

The Lakeland 100 demands a training base that very few ultra runners have when they first enter. Plan at least 12-18 months of specific preparation. The key physical demands are volume tolerance (you will be moving for 24-40 hours), technical fell running ability, and the resilience to keep moving through a second night of running.

Back-to-back long runs — Friday evening to Saturday evening, mirroring the race schedule — are the cornerstone of L100 preparation. Building to back-to-back runs of 5-6 hours each, on rough terrain, carrying race-weight kit, is the most race-specific training you can do. Night runs are essential — aim for at least one significant night running session per month in the build phase.

Qualifying via the Lakeland 50 (in under 16 hours) is the entry requirement, not just a bureaucratic hoop. Use your L50 attempt to learn half the L100 course, test your kit in race conditions, and understand what the second night on the L100 will feel like on the same terrain.

Pacing & Support

Pacers are permitted from certain checkpoints in the latter half of the race. Check the current rules on the official website as these can change. Even without pacers for the first half, a well-briefed crew at accessible checkpoints can make an enormous difference — hot food ready, kit changes organised, a fresh pair of feet walking you out of the checkpoint.

Pacing strategy: the race starts at 6pm in summer with several hours of daylight. Many runners go out comfortably in the first hours and arrive at Wasdale in the dark feeling good. The wheels typically come off in the Buttermere-to-Keswick section or in the Haweswater/Kentmere section of the second half. Build your schedule based on conservative leg estimates and leave yourself buffer at each checkpoint rather than banking on a fast final section.

Nutrition Strategy

The 14 checkpoints are stocked with hot food — soup, pasta, rice, sandwiches — alongside gels and isotonic drinks. Don't rely on them as your sole nutrition source; carry your own fuel between checkpoints. Aim for 250-350 calories per hour in the early legs, and be prepared to drop to liquids and easy carbs as fatigue builds in the second half.

Caffeine management matters over 30-40 hours. Many runners avoid caffeine for the first 20-24 hours, then use it strategically to manage the second night. Test your caffeine strategy in training — a gel or caffeine tablet at 3am is very different from your usual morning espresso.

All 14 Checkpoints — What to Expect

Each checkpoint is staffed by a volunteer team and stocked with food and hot drinks (except CP1 Seathwaite, which has cold drinks only). Water and cola are available at every checkpoint. You must check in at every checkpoint — missing one means disqualification. Plan how long you will spend at each: 5 minutes to eat and move on is the goal; 20 minutes is a luxury you may not have.

Where DNFs Happen and Why

The 40-50% DNF rate is spread across the course, but certain points see disproportionately high dropout rates:

• Wasdale Head (CP3, ~19 miles): The first major reality check. Runners who have gone out too hard or badly navigated Eskdale sometimes withdraw here. It's also a long, remote drive for any crew, which demoralises some runners who find themselves alone at a major low point.
• Buttermere (CP4, ~26 miles): The first night is ending or just ended. Fatigue hits hard. The milkshakes and hot dogs at Buttermere can feel like a final luxury before the long push to Keswick and Dalemain.
• Braithwaite (CP5, ~33 miles): Has a 12-hour cutoff for a 6pm start. Some runners arrive just in time; the pressure compounds existing fatigue.
• Dalemain (CP8, ~60 miles): Halfway. The Lakeland 50 starts here and the atmosphere changes — fresh 50-milers surge past tired 100 runners. This psychological contrast causes some experienced runners to withdraw at a point where, had they continued, they would have finished.
• Mardale Head (CP10, ~76 miles): Remote and late in the race. Foot problems, blister breakdown, and accumulated fatigue are the main causes of withdrawal here. The climb out of Mardale into Kentmere feels enormous at this point.

Night Running Strategy

The 6pm Friday start means darkness falls within 3–4 hours. Most runners face their first night somewhere between Eskdale and Buttermere. The second night falls on sections 3 and 4 of the course — Howtown, Haweswater, and Kentmere. Plan for both nights in your preparation.

Key night running tips for the L100:

• Carry two head torches and spare batteries — a primary torch plus a backup, always. A torch failure in Eskdale at 2am with no backup is a race-ending disaster.
• The road book is harder to read at night. Laminate your key navigation notes or use a head torch attachment so your hands stay free. Practice reading the road book while moving in the dark on recce runs.
• Night cold can be significant even in July — the hills hold temperature drops of 5–10°C compared to the valleys. Your emergency base layer kit must be accessible quickly, not buried in the bottom of your pack.
• Hallucinations are common in the second night. They are normal, they are not dangerous, and they pass. Know that they may happen and brief your pacing team so they are not alarmed. Running with someone reduces this effect significantly.
• Pace drops at night — accept this and build it into your schedule. A night-time mile on rough terrain takes considerably longer than the same terrain in daylight. Don't fight it; run to effort.

Drop Bags

The race allows drop bags at certain checkpoints — check the current rules and designated drop bag points on the official website, as these change year to year. Typically, drop bag access is available at the major checkpoints accessible by road. A well-packed drop bag should contain: dry socks, a fresh base layer, your next leg's nutrition already packed into a bag, any blister supplies, and a brief written note from yourself (written when fresh) with encouragement and key reminders. That note can matter enormously at mile 70.

Training Structure for the L100

Plan 18–24 months from serious training start to race day. The L100 demands a training volume and race-specific conditioning that most ultra runners build over several years of fell and trail running, not months.

Year One — Build the Foundation

Consistent weekly mileage of 50–70 miles on varied terrain, including genuine fell running with significant elevation. Complete the Lakeland 50 (your qualifying race) during this year. Use the L50 to learn the back half of the L100 course and to experience the race logistics, checkpoint routine, and night running in a supported context.

Year Two — Race-Specific Build

Increase to 70–100 miles per week in peak training blocks. The cornerstone sessions for the L100 are back-to-back long runs — a Friday evening run of 4–5 hours followed by a Saturday run of 6–8 hours, mirroring the race schedule. Night runs are non-negotiable: at least one significant night training run per month in the 6 months before the race. Attend all official recce days. Complete at least one full section recce under poor weather conditions.

Race Weekend Logistics

Race HQ is at John Ruskin School in Coniston. Registration opens on Thursday for both races. Collect your bib, road book, and Harvey map at registration — do not leave these in the car on Friday morning. The Friday evening pre-race briefing is mandatory.

Coniston is a small village. Book accommodation well in advance — the race sells out quickly and so does all local accommodation. Camping is available on site. If your crew is following the race, they will need to plan their own transport and accommodation for the full weekend — the route passes through some very remote areas and driving between checkpoints takes significantly longer than you might expect on the map.

Your kit will be checked at registration. Do not arrive hoping that a borderline kit item will be waved through — race officials take the kit list seriously. If in doubt about any item, contact the race organisers before race day.
