The Salomon 50k Trail Race Ultra

The Salomon 50km Ultra Trail Marathon - a spectacular trail race across the Lakeland Fells and not for the faint hearted!
Category: Run
Event Grade: Very Hard


The Salomon 50km Ultra Marathon Trail Race is graded 'Very Hard'. This ultra marathon distance race is not for the faint hearted. The course is extremely well marked with RED FLAG’s and A5 KMF Pink/Blue Arrow’s marking ‘major’ directional changes, but still we require you have the knowledge of how to use a map and compass or at least download the gpx file, which we can supply on request. 

This race is for the experience trail runner & is a tough course, but is also a classic mountain trail race with a tough record to beat, set by Donnie Campbell in 2016. Saying this, you don’t need to be an elite runner to compete, but you must have completed a marathon distance, at least, over hilly terrain and technical paths before entering. The course takes in some of the Borrowdale, Buttermere and Newlands Valley's finest trails and view’s. The race is run in a clockwise direction. The start is from the KMF events centre at Crow Park. 

The course is a mixture of wide open trails, single track (fast & technical), big long ascents & fast technical descents, open valley running & very remote feeling trails around the back of the Buttermere, Crummock Water and Newlands Valley area’s. It takes in remote locations that you will not have run in before. Expect to be blown away by the views of the 4 valleys we take you through & overwhelmed by the quality of running you will be immersed in. This race is not only tough, but is also one of the most scenic races of its type in the Lake District, taking mountains and lowlands in its stride offering you one of the best trail running experience in the country.

Distance: 51km
Ascent: 1995m

Route Description

The 50km route starts from inside Crow Park, heading down the east side of Derwent Water, it then crosses the road & heads up the fell to the NE corner of Great Wood. Mountain trails then take you above Walla & Falcon Crags taking you in to the hidden valley of Watendlath, which has some amazing single track to float along. At the head of the valley you ‘grind’ out over Grange Fell and descend the fast and technical track to the Rosthwaite Institute & your 1st Feed Station (CP 1) of the day. Watered and fed you will then head West up the track running parallel with the Honister mines road to your 2nd Feed Station (CP 2). Now you follow the old miners track up and over the fell, passing Dubs Quarry round the back of Fleetwith Pike and into the stunning Buttermere Valley by a very technical track. The route now takes you around the southern shore of Buttermere and then Crummock Water to the 3rd Feed Station (CP 3) of the day at the foot of the lake on the western most tip. Next follow wonderful single tracks on the lake-shore to run back up the north side to the next hidden gem, the Bluebells of Rannerdale, famed far and wide. From here it’s up and over the hause at the head of the valley and then round the extremely remote single track hugging Whiteless Pike, Addocombe Beck and then through the hause between Sail & Ard Crags. Dropping quickly down the technical and rocky track you end up in the Newlands Valley and the 4th Feed Station (CP 4) and using a small amount of road you run towards Little Town, before heading back onto the miners tracks and down the Newlands Valley arriving at the 5th Feed Station of the day at Hawes End (not a timed CP, so no dibbing here). From here you're on the final leg and you run along tranquil woodland trails until Portinscale village is reached, crossing the suspension bridge to head back into Keswick via the ‘Bob Graham Round’ finish. Once on the streets of Keswick you will be quickly directed, by marshals, into the back alley running behind Booths super market to bring you through the final sections of the race and the home straight passing the boat yard and to your glory finish back in Crow Park. 

The route is a perfect training run/race for the UTLD Lakeland 50 at the end of July.

Event Details:

The race starts from Crow Park at 06:00

There are 4 checkpoints (CP's) around the course, for timing/safety purposes, which all competitors must visit & dib in at with their 'timing card', failure to do this will mean disqualification from the race & putting the whole event at risk. Please don’t forget, this is for your safety. At these CP's there will be feed stations where you can fuel up with water, juice & some food. 2 marshals will be present at each CP. 

There are cut off's at the following CP’s: 
•    Honister Slate Mines CP (09:45 – 3 hours and 45 minutes after the start and 18km in distance)
•    Crummock Water CP (12:00 – 6 hours after the start and 28km in distance). 

This gives you ample time to get to each of these CP’s. In order to make the cut offs you need to move at an average of 5.5km per hour over the varied terrain of the race. This is a fast walk!  

If you are outside the generous cut off we are afraid you will be pulled from the race, so please make sure you are ready for this distance and ascent. 

If you are timed out, we can’t lay on the provision of transport to take you back to the race HQ, you must make your own way back to the events centre & hand in your 'Timing Card', failure to do this could result in the MRT's being called out to search for you, so please make sure you do this.

There is a bus service running at regular intervals from both the Honister Slate Mines and Crummock Water, should you not make the cut offs.
