The Route

From Loch Ness
to London

1,055km. Seven stages. The length of Britain.

Monster is not a distance to survive in a single day. It is a journey you take on one stage at a time.

Day one opens beneath Ben Nevis with a 5km swim in Loch Ness. Then five days on the bike heading south: the Glencoe Pass, the shores of Loch Lomond, Glasgow, the Scottish Borders, the crossing into England, Shap Pass, Lancashire, the West Midlands, Shakespeare’s country, the Chilterns and down into Windsor. On day seven you run 50km along the Thames Path into London.

By the end of the week you are 1,055km from where you started, at the other end of the country.

Challenge

3/5

Overview

It begins in Loch Ness.

Starting on the shores of the fabled loch, home to a mythical monster, you begin your challenge by braving the waters with a 5km swim. The course is marked at 500 metres, close to the shoreline, so you swim laps and can exit the water at the end of any lap if you need to. A wetsuit is compulsory.

The swim is fully supported from the moment you enter the water. Kayaks, paddleboards, a dedicated safety boat and shore-based medical cover stay alongside participants throughout. While you are swimming, your main luggage is taken directly to your hotel room. You only need a small transition bag for your cycling kit and swim gear, which we collect once you are out.

Then changing facilities, and a short ride to Fort William, home of Ben Nevis, the UK’s tallest mountain.

Seven days start here.

Highlights of the day

  • The 5km swim in Loch Ness
  • Fort Augustus and the Caledonian Canal
  • The ride along the Great Glen
  • Arriving at Fort William beneath Ben Nevis

Top Tip

The best preparation for the Loch Ness swim is time in open water, not more time in a pool. Get comfortable in cool, natural water and in a wetsuit. Neoprene gloves, socks or swim boots and a neoprene cap make a real difference, and a brightly coloured silicone cap over the top helps our safety team see you.

Challenge

5/5

Overview

The first full day in the saddle, and the most dramatic scenery of the week arrives immediately.

You take on the climbs of the Scottish Highlands, including the iconic Glencoe Pass, then the twisting lanes on the shores of Loch Lomond, before reaching Glasgow and the day’s finish.

Three fully stocked feed stations along the route, with hot food at the middle stop.

Highlights of the day

  • The climb through Glencoe Pass
  • Rannoch Moor
  • The lanes along the shores of Loch Lomond
  • Arriving into Glasgow

Top Tip

This is the day you will want to photograph, and it is also the day it is easiest to go too hard. Glencoe will make you feel invincible. There are five more days of riding after this one. Ride it at the pace you could repeat tomorrow.

4/5

Overview

This is the day the map starts to mean something.

Following the rugged landscape, you cut through the Scottish Borders as you head south towards England, taking in more incredible scenery as you take on the next leg of your challenge.

You began the week on a loch in the Highlands. Today you leave Scotland.

Highlights of the day

  • The Scottish Borders
  • Crossing the border into England
  • [Confirm specific named landmarks and towns]

Top Tip

The border crossing is one of the best photographs of the week and one of the best moments to take in. Stop for it. You will want the picture and you will want the memory.

Challenge

5/5

Overview

The halfway point in your challenge, and the longest day on the bike.

You head over the incredible Shap Pass and through the undulating terrain of the Lancashire countryside. It is the day the week asks the most of you, and it is usually the day people discover what they are actually capable of.

Three feed stations, hot food at the middle one, and a support vehicle on the route.

Highlights of the day

  • Shap Pass
  • The Lancashire countryside
  • Reaching the halfway point of 1,055km

Top Tip

Eat before you are hungry today, not when you are. Use all three feed stations even if you feel fine at the first one. The riders who struggle on day four are almost always the riders who under-ate on day three.

4/5

Overview

This is the day the group tends to come together.

By now the challenge is starting to take its toll. You face a fast and flat start to the day, which is welcome, but keep some energy in the bank: you take on the hills of the West Midlands towards the end of the day’s ride.

Four days in, everyone knows everyone, and the riding gets noticeably more social.

Highlights of the day

  • A fast, flat opening
  • The hills of the West Midlands
  • [Confirm specific named landmarks and towns]

Top Tip

Day five is a mental day more than a physical one. The novelty has worn off and London still feels a long way away. Ride with someone. It is the single best thing you can do for your legs today.

Challenge

4/5

Overview

Your last day in the saddle, and another long one.

You pass through Shakespeare’s country and the beautiful Warwickshire countryside, then battle your final hills of the trip through the Chilterns before descending into Windsor.

Tomorrow you run.

Highlights of the day

  • Shakespeare’s country
  • The Warwickshire countryside
  • The final climbs in the Chilterns
  • The descent into Windsor

Top Tip

Look after your feet tonight. Six days of cycling and then a 50km run is a strange thing to ask of a body, and the riders who finish the run comfortably are the ones who sorted socks, shoes and a bit of stretching the evening before.

Challenge

5/5

Overview

The final leg of your journey, and an ultra-marathon to complete.

You follow much of the Thames Path as it winds its way into the capital. Six days of cycling in your legs and a marathon and a half in front of you. Nobody arrives at this morning fresh, and that is precisely the point.

By the time you reach the finish you will have joined the list of Monsters who have taken on the full journey from Loch Ness to London. You are within touching distance of your goal and the embrace of your fellow finishers.

The 2027 final run will feature chip timing. Completion is still the story.

Highlights of the day

  • The Thames Path
  • Running into the capital
  • The finish, and the people you finish with

Top Tip

Start slower than you want to. Everybody sets off too quickly on day seven because the end is finally in sight. The Thames Path is long and flat and it rewards patience. Run the first 10km at a pace that feels almost lazy and you will have a very different last 10km.

At the finish

Friends and family are welcome. Every finisher receives a commemorative medal and a finisher T-shirt, and is welcomed with food, drink and a finish-line celebration shared with fellow participants, friends and family.

After seven days, there is no better place to share the moment with the people who supported you through it.

Navigation is handled

You will receive GPX files well before the event, so you can load the routes onto your bike computer or watch before you arrive. Key locations such as feed stations are clearly signposted, and every participant is tracked throughout the event. If you leave the planned route our team can see it, and can contact or assist you.
