Coastal Trail Series - Exmoor (CTS) (/Events/Coastal Trail Series - Exmoor

Wow. Ran the June 2021 as my first Ultra. It said it was tough and it didn’t disappoint. Really well organised with great Marshall’s at each point. Weather was stunning the whole day. The killer for me was the 10k loop you had to do to finish the race - brutal on an already tired mind. Great day ...


The HOWUM - 30 Miles

2021 race: A really fun, relaxed but impeccably organised event. Beautiful course taking in the source of the Severn. Even the forestry bits are mostly quite open with big views. There is over 1000m of ascent but the gradients are mostly gentle and most of the climbing comes in the first half, so...


Run to the Sea Brighton 50km

My first trail ultra ,was a great route ,first half flat with great scenery and lots of shade ,second half hilly with great views ,very well marked course ,aid stations well stocked and great friendly atmosphere among the runners .Would recommend .


Ultra X Spring Trail Series

2021. Lovely course apart from the last couple of miles which were up a steep boggy path. Good support at the aid stations and overall pretty seamless. Only one point to note: if your colour blind red/green good luck trying to follow their little red flags. Genuinely, I'm colour blind and found i...


Fox Ultra

I ran the inaugural Fox in 2017, came back the next year but DNF'ed at the 4th checkpoint due to a dodgy knee and in 2019, I ran the half-marathon option at 24 weeks pregnant. The Fox was my first ultra and will forever hold a special place in my heart. The route is stunning, with the right balan...


Hell On The Humber

Good heavens. If there's one thing this event can do, it's get people of all abilities ultra running. You'd think running exactly 2 miles out and 2 miles back, along a suspension bridge, over and over again, completely exposed to wind and rain from every direction, would put people off but everyo...


Ladybower 50

Despite an assurance to the contrary from the organisers, this lapped race around Derwen*****er turned out to be on a strongly undulating course. But what a course! A third is road and the rest is a mix of various kinds of trail from woodland dirt paths up to the steep, stony track right at the h...


Kings Forest 50k

This is a relatively fast, flat 50k trail race held amongst the fire tracks and forest paths of Kings Forest. The Thetford Forest area is known for being a forestry area with many wide, straight paths crossing each other at right angles which means many parts of the route all look the same as eac...

ADVICE NEEDED, PLEASE - How long should you stop for...?

Hi guys So, with less than three weeks to go until my first ultra, I'm steadily learning lessons and giving huge thought to all the variables, in an attempt to arrive at the race with a strategy that will see me through. The articles linked to on this site are great, and the most important thing for me to get my head around is pacing. I did my final long run yesterday. 31 miles at a 'total' pace (so, with stops) of 8'47"/mile. Now, it is very clear to me that to be successful over 52-53 miles, I HAVE to slow down A LOT from the running pace that gave me that overall pace, and I'm learning lots by reading on here etc. BUT... What I have NO feel for is how long to stop for. My plan is to stop at all of the checkpoints (six, I think) at least, and impromptu extra stops as needed. But how long to stop for? On my training runs the stops are only the duration of the 'stop-reason' e.g. a quick wee, a stretch, quickly buying a bottle of water etc, so typically 2-4 minutes max. each time. In my ultra, will I 'benefit' from planning to stop for longer, and if so, what should I 'do' there? Stretch? Sit down? Put my feet up? Obviously I'll spend time eating etc, but it's really whether my race will go better if I 'make' myself stop for longer than I usually would... I realise that everyone is different in terms of the breaks their bodies need, but any general guidance on this specific query would be massively appreciated! Thanks! Ben x

First Ultra next year

Hi all. I turn 40 next summer -2020- and want to celebrate it with an ultramarathon. I’ve done a few half marathons and trail 10ks. I usually train CrossFit and powerlifting. I’ve a powerlifting comp this July. Any advice for a newbie or am I thinking too far in advance?

Ultra-Trail Snowdonia 2019

Billed as 'the UK's answer to UTMB', UTS100 and UTS50 burst onto the ultra scene last year. You know a 100 miler is tough when the winner finishes in 34 hours 5 minutes and is more than 5 hours ahead of any other finisher. This was Marcis Gubats who smashed the event last year. There was a DNF rate of 71.7%, and only one female finished - Jamie Aaron in 41:23:16. The 50 mile event had a DNF rate of only 22.3%, but it was still a toughie. Bear in mind all entrants were experienced mountain runners. The winners were Oliver Thorogood (11:30:25) and Nicky Spinks (13:49:30). It says something when a race attracts names like Marcis Gubats and Nicky Spinks on its first year. There seem to have been a few tweaks this year - the cut-off for UTS100 has changed from 48 hours to 50 hours. However, the route was 103 miles last year and is 106 miles this year, so this may not affect the completion rate. The cut-off for UTS50 has changed from 36 hours to 34 hours, potentially making it tougher. UTS100 starts at 1pm on Friday 10th May with an ascent of Snowdon. It consists of 2 lopps of approximately 53 miles each and the total ascent is 32,800 feet. UTS50 runners will complete the second and more southerly loop of the 100 course. They will run 53 miles and climb 16,730 feet. They start at 5am on Saturday. These events are two of the toughest UK mountain races and it will be interesting to see if last year's records can be beaten.

The South Downs Way - Devil's Challenge

The Devil's Challenge is another of XNRG's extremely popular multi-day races. It takes place over the Bank Holiday weekend, with around 150 runners aiming to complete the 97-mile route over the three days. Runners will set off from Winchester on Saturday morning and hope to arrive at the other end of the South Downs Way - Eastbourne - on Monday. There are fully catered overnight stops on Saturday and Sunday. These will include guest-speakers. This year's speakers are Anna-Marie Watson (whose achievements include 7th female at UTMB 2017, a win at Half MdS Fuerteventura 2017 and 2nd place at MdS 2015) and Health and Fitness Coach Victoria Rawlinson. Victoria will be speaking about sleep - an important topic for ultra runners. The South Downs Way offers chalk cliffs, beautiful scenery, sea-views and picturesque villages. Runners will climb 3815 metres over the three days and gain valuable experience in multi-stage racing. Both of our runner reviewers awarded the event 5 stars. Good luck to everyone involved.

Badwater Salton Sea 2019

Badwater Salton Sea is the second race in the 2019 Badwater Ultra Cup. This year, 16 runners are attempting the Cup - Badwater Cape Fear, Badwater Salton Sea and Badwater 135. In total, 110 runners are expected on the start line on Sunday. They make up 43 teams of either 2 or 3 people. Teams have to run together throughout the event. They will set off at 6:30 local time (2:30pm UK time) on Sunday and have up to 28 hours to complete the 81-mile route. This means most will finish on Monday. The start line is on the shores of Salton Sea in Salton City, California. Salton Sea is a lake known for its high salt levels and it is 243 feet below sea level. The race finishes on the summit of Palomar Mountain, which stands at 5500 feet above sea level. Along their journey, the runners will traverse the deserts and mountains of Southern California and climb a total of more than 9000 feet. The route is a mixture of road and trails, and 8 miles are run through the Anza-Borrego Desert State Park. The fastest team in 2018 completed the route in 15 hours and 36 minutes. We'll be watching to see if any teams top that this year. Good luck to everyone involved!

The Fellsman 2019

The 57th Fellsman takes place this weekend. Runners will set off from Ingleton at 8:30am on Saturday, and they have until 3:30pm on Sunday to reach Threshfield - a route of around 61 miles across the Yorkshire Dales. The majority of the route is not a set course - runners must find their own route between the checkpoints. The majority is run on private land - these are not footpaths marked on a map, so navigation skills are a must. As most of the route is off-limits for the rest of the year, it cannot legally be recced prior to the race. This is a traditional fell race and certainly a challenge. The terrain can be boggy and is often remote, and the total elevation is around 11,000 feet. For safety, participants must run in groups of four during hours of darkness. Anyone not already in a group will be held at a checkpoint until a group can be formed by the marshals. They will be awarded waiting time for this. Groups must stay together until otherwise instructed by marshals once it is daylight. Despite the obvious difficulty of this event, all nine of our runner reviewers awarded it 5 stars. RunUltra's Web Administrator, Kate, is running this year. Her blog gives you some idea of the extensive kit list required to undertake this event: https://peaksprincess.com/2019/04/19/my-last-will-and-testiment-before-fellsman/ Good luck to Kate and all of this year's entrants.

Highland Fling Race 2019

The Highland Fling Race is one of the biggest UK ultras with 1000 successful ballot entrants and an average of around 800 runners taking part each year. The 53 mile event hosts the Scottish Ultra Trail Championships with Scottish Championship medals awarded to the top 3: men, women, vet men, vet women, male teams and female teams (provided they are members of Scottish Athletics). The route covers the southern section of the West Highland Way from Milngavie (near Glasgow) to Tyndrum. The West Highland Way is Scotland's oldest official long distance footpath at around 95 miles. The remaining 42 miles from Tyndrum to Fort William form the Devil O' The Highlands Ultra in August. There is also the full West Highland Way Race covering all 95 miles in June. The Highland Fling route takes runners through the breathtaking Loch Lomond and The Trossachs National Park. The scenery is stunning, and the views are well worth the 7500 feet of climbing. Although there is a more technical section of around 7 miles along the lochside, the remainder of the route is runnable, and the event attracts both seasoned and new ultra runners. The cut-off is 15 hours. Last year's winners were Kyle Greig (7:06:58) and Rachel Normand (8:22:23). It looks like there may be some light rain on Saturday, but that is unlikely to hold back this year's runners. Good luck everyone.

Manchester to Liverpool Ultra

Around 300 runners will be spending Good Friday running 50 miles from Manchester to Liverpool along the Trans-Pennine Trail and banks of the River Mersey. The route reverses the popular Liverpool to Manchester Ultra (L2M Ultra) from previous years. GB Ultras events are some of the most visited pages on our listings site, and our 10 runner reviewers were full of praise for the L2M event. Runners set off from near Manchester United's Football Ground at 6am and have until 7pm to finish the route. The event is part of the GB Ultras 50 Mile Grand Slam. Given the 4-day weekend (for many), they will have plenty of time to recover and enjoy their Easter Eggs. The event is sold out, and we expect that a number of our members are running. Good luck to all involved!
