About the race

Spanning 7 days the Monster Triathlon is the UK’s ultimate multi-sport challenge

It starts with a 5km swim in Loch Ness, before 5 stunning days on the bike and finishes with an ultra-marathon along the Thames. For those unable to tackle the beast in one go we are offering Swim, Cycle and Run only packages this year. You’ll pass lakes, climb mountains, ride past fields, fly through villages, cross rivers and conquer hills. As well as being an epic challenge The Monster Triathlon also highlights the beauty and diversity of the UK.

Special event with something for everyone

Did this in 2018 and it was a fantastic event.  Some entered to go fast (and they were very fast!) and some entered to just "enjoy the ride".  I wouldn't have thought such a mix of people would work but it really did - there was something for everybody.  Very friendly and helpful support crew, stunning route exploring the best of Scotland and England.  I really can't fault the event.  The swim, bike and run were all very special experiences.  Do it!

Bucketlist Multi Day Event

Monster Triathlon

Relaxed format swim bike run challenge over 6 days taking in the beautiful backdrop of the UK coutryside.

If you are looking for a change from racing but still want a challenge but with all administration taken care off this is a must do event!

I would highly recommend it.

One in a lifetime epic adventure

Its not a race, but a chance to swim in Loch Ness, ride to London over 5 days with all the food and drink you need, bags transported and a great crowd to ride and run with.

Its not easy.  Its not timed, but you have to get to the next stop, 120 miles away over 5 days then run an ultra marathon along the Thames Path.

Great experience, great organisation and can use it for training or social challenge.  May seem expensive but to get all food and drink included, 6 hotels and all your bags transported it is a good value experience.

You will need to self navigate the bike routes with gpx files but allows you to ride at your own pace, hard or easy but see a great section of the country on the way.
