Day 15km swim in Loch Ness (Cycle to Fort William)

Starting on the shores of the fabled Loch Ness, home to a mythical monster, you’ll begin your challenge by braving the waters with a 5km swim before tackling a short ride to Fort William, home of the UK’s tallest mountain, Ben Nevis.

Day 2Cycle from Fort William to Glasgow

Day 2, and the first full day on the bike, will see you tackle both the climbs of the Scottish Highlands, including the iconic Glencoe Pass, and the twisting lanes on the shores of Loch Lomond, before reaching Glasgow and the day’s finish.

Day 3Cycle from Glasgow to Carlisle

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

Day 4Cycle from Carlisle to Haydock

The halfway point in your challenge sees you take on the longest day on the bike as you head over the incredible Shap Pass and through the undulating terrain of the Lancashire countryside.

Day 5Cycle from Haydock to Kidderminster

As your challenge starts to take its toll, you’ll face a fast and flat start to the day, but keep some energy in the bank as you tackle the hills of the West Midlands towards the end of the day’s ride.

Day 6Cycle from Kidderminster to Windsor

Your last day in the saddle sees you tackle another long day, passing through Shakespeare’s country and the beautiful Warwickshire countryside. You’ll battle your final hills of the trip through the Chilterns before descending down into Windsor.

Day 7Run from Windsor to Richmond

The final leg of your journey, and an ultra-marathon to complete as you join an impressive list of Monsters who have taken on the challenge of the UK’s toughest triathlon. Following much of the Thames Path as it winds its way into the capital, you’re within touching distance of your goal and the embrace of your fellow Monster finishers.

"Bucket List event! A once in a lifetime opportunity. Just the best experience ever, swimming in Loch Ness with the most dramatic backdrop, jumping onto our bikes for an epic 5 days of cycling through the rolling British countryside topped off with the most beautiful run along the Thames. The Monster Team were truly outstanding from the outset making sure we were all very well looked after and making it a very chilled out event allowing all participants to enjoy the week at a pace to suit them meeting great new friends at the same time.  Highly recommend!!
