The Lakeland Trails 100k Ultra is our ultimate trail with its iconic midnight start, taking the challenge to a new, but achievable level for a truly memorable journey encompassing the finest trails the Lake District has to offer.
The 55k Ultra is a testing ultra marathon course through some of the most dramatic mountain scenery in the Lake District. The tough, challenging course will certainly live up to its billing as the most picturesque ultra marathon in the UK.
As well as those whose goal is to complete their first Ultra, expect things to be competitive at the front. The 2021 100k also doubled up as the British Athletics Championships with runners George Foster and Team inov-8's Merryl Cooper setting a high bar for future runners with course records of 9h30m11s and 11h32m19s respectively.
One of the great things about the Lakeland Trails Ultra is those at both ends of the field can expect a warm reception from the friendliest marshals you'll find!
The 55k route includes 3 mountain passes, with 7,000 ft ascent along with 5 well-stocked feed stations.
The 100k route adds in an extra 2 passes, 3500 ft more climbing and 3 feedstations.
The 23k and 14k routes share some of the final sections of our Ultra courses with spectacular views guaranteed.
The courses are all fully waymarked and marshalled with gpx files available.
The 100k Ultra is worth 4 ITRA points (courses validated for 2022) and the 55k Ultra is worth 3 ITRA points . (Please note - to qualify for points in the 55k you must run in the 'Race' and not the 'Challenge')
The start and finish arena will be quite a party, with entertainment, food stalls, trade and retail stands and PA commentary.

Professional photo memento taken out on the course by professional sports photographers James Kirby and Paul Mitchell

Ultra 55k and 100k runners need to collect their race numbers and have a compulsory kit check before setting off. Please allow plenty of time for this and if you’re running in the 55k, please try and register on the Friday between 2pm and 8pm. Please note, there are NO exceptions to kit check requirements.

If you’ve got any questions about your entry, please go to the Enquiries desk on the right-hand side of the main marquee and a friendly face will help you.
Please note there are no entries on the day and entries cannot be transferred to another runner. Runners competing with someone else's number will be disqualified and will not be eligible for prizes or appear in the results. We will also prevent them from taking part in future Lakeland Trails events, such is the safety risk if something were to happen to a person whose details we don’t have on our system.
There will be a baggage storage area adjacent to the main marquee and Ultra 100k runners will have the option of leaving a bag to collect at the Glenridding Checkpoint.
Participation Statement
All participants in the Ultra must agree with the Participation Statement which is available to download HERE.
(There are no compulsory kit requirements for the 14k and 23k runs)
Our kit check is run by our Crew & volunteers who are part of the team helping you to have a safe and enjoyable event. While kit check can be a stressful part of registration, please treat them with respect and remember that any questions they may have about your kit are simply for your safety.
Please note that, regardless of the forecast or conditions on the day, there will be no change to these kit requirements, which form part of our approved Risk Assessments and Event Management Plans. Even on a hot summer’s day, it is not unknown for a hailstorm to roll in and for the temperatures to plummet. Some sections of the course are at a high elevation and would take some time to reach in case of an emergency.
Please note photographic ID will be required (Driving License / Passport) to collect your Race Number

Bag Drop - 100k runners can leave one bag at our bag drop in the marquee - nothing larger than a 20l rucksack. This bag will be available at the Glenridding checkpoint. You will need to affix the baggage label that you receive at registration to this bag and leave it in the marquee no later than 8pm on Friday. The bags will be returned to Ambleside from the Glenridding checkpoint once it has closed to the Ultra 55k runners and the Crew have cleared everything away.
If you need to retire from the event, it is ESSENTIAL that you hand in your race number and timing dibber and / or tracker at a checkpoint or at the finish line. We have had instances when people have not done this and it leads to worry and a long night for our crew as we ensure unaccounted for runners are safe.
If you retire, we ask in the first instance that you get back to Ambleside under your own steam if at all possible. Maybe you could be collected from a checkpoint by family / friends? So long as you have confirmed your retirement with marshals at a checkpoint, and handed in your number and dibber/tracker, you do not need to return to Event HQ.
If getting back to Ambleside is not possible, we will do our best to bring you back with our checkpoint crew but there may be a significant wait.
If you retire at a checkpoint, an extra pair of hands is always welcome!
All Ultra 100k runners and those 55k runners who selected the option will be tracked and timed using GPS trackers.
You are liable for the safe return of your tracker / dibber. Non-returned ones will be charged at £50.
Follow your runners using the tracking links here:
100k (all runners)
55k (those runners who opted in)

The most up-to-date gpx files are available to download from the the following links: Ultra 55k 280623 and Ultra 100k 280623 (right click and 'Save as' to download the files).
The shorter Trail Run 23k & 14k cross over sections of private land so we are unable to share the GPX files for them.
All courses will be well marked and marshalled by our magnificent Lakeland Trails volunteers, all of whom work hard to make your run as enjoyable and safe as possible. The courses have a variety of terrain, mainly beautiful, scenic hard packed trails with the occasional muddy section!
Please stay alert on any road sections and keep close to the right hand side. Our marshals don’t have authority to stop traffic, so please be prepared to slow down and wait if necessary.
Please be attentive at the end of your event as the route takes you through one of our parking fields.
If you think the terrain is too tricky, it’s fine to slow down or walk and take in the views! Some gates on the course may not be staffed so if you arrive at a closed gate, please close it after you – there will be lots of lambs in the fields and we want them to stay there. There are sections of private land which may only be used on race day and please put any litter in your pocket until you reach a bin.
For safety, in ear headphones are not allowed - but we do allow bone conductor headphones which enable peripheral sound to be heard.
Please also be considerate to other trail and road users. We share access with them and we rely on the goodwill of others to make our events possible.
VERY IMPORTANT: DOGS AREN’T ALLOWED ON THE COURSE
