As a lover of mountains I'm a keen trekker and also enjoy cycling and yoga.

I'm also managing social pages, developing new marketing strategies or working on new web projects.


James Eacott
Online Communications and Editor

James writes our regular email newsletters and ensures that our RunUltra members are kept up to speed on the latest trends, reviews and articles about ultra running. James is also a keen ultra runner and has been getting some pretty impressive placings in his recent ultras.

Here are a few words from James about his passion for running:

I’ve always been a keen sportsman at school, playing most team sports, but it was at Exeter University that I developed a love for the intense training regime that came with rowing for the 1st VIII.

Upon graduating with a degree in Geography in 2008, I needed to fill the gap that rowing left. I took up long distance running and never looked back, entering the Atacama Crossing before having run even a half marathon. It was a traumatic yet truly wonderful experience. Over the course of that race, my eyes were opened to a world of fascinating people and breathtaking environments. The limits of human performance had been questioned, and this left me gagging to find my own boundaries. The Atacama has led me to ultras around the world, from the Amazon basin to the Himalayas.

After 4 years of little else but running, I had a desire to shake up my training so began competing in triathlons and was fortunate to represent GB at the Age Group level at the World Championships. I now mix ultra marathons with triathlons, because I clearly didn’t have enough on my plate as it was. I find they actually complement each other rather well.

I recently returned from my favourite ultra to date - the Everest Trail Race. In 2015 I will be racing in Madrid and Geneva, and have eyes on The Coastal Challenge in Costa Rica in early 2016.


Elsa Trujillo-Dennis
Web Admin Manager

Elsa manages the relationships with our organisers and is Chief Listener to their needs and requirements. She also keeps our race pages, race reviews and articles up to date. Technically an archaeologist but with a background in multimedia events and content development, Elsa has worked for many years in web admin management and content development for exhibitions, and speaks fluent Spanish and English. She's an admin pro and we are indebted to her eye for detail and determination to get the race events live on the RunUltra site from around the world as quickly as possible.

Here's Elsa's summary of her life to date:

A keen skier from a very young age, my love of mountains and high-altitude trekking has taken me to many wonderful places around the globe to witness some of its many wonders. Favourite memories include the view from my first 3000m summit in the Pyrenees; descending the Mer de Glace, the first rays of daylight kissing the top of Mount Everest and the impressive Milky Way on a dark night over Mount Kilimanjaro. I also love to combine these trips with more historical ones to satisfy my fascination with the past so I’m forever scrutinising the globe for new destinations and new people to meet.


Adam Flowers
Social Media Manager

Adz is an enthusiastic, motivated & experienced social media guru with a love for performance analytics. He’s responsible for creating memorable cross-platform campaigns and producing engaging content for our Ultra running community across Facebook, Twitter & Google+.

Adz has quickly established himself as an expert on social media. After proving his abilities at Hampton & Richmond Borough Football club, he joined hotels4u.com before taking up a challenging role as Social Media Manager for Thomas Cook UK. We love Adz for his unrelenting passion & knowledge of digital media.

Here’s more from the man himself on his life and career to date:

KFC. For most folk, those three letters conjure up an image of freshly cooked, slightly greasy chicken. For me, it’s a constant reminder that I can achieve anything I desire.
There’s no getting away from the fact that social media is probably one of life’s greatest treasures. Rapid technology change only serves to inspire & fascinate me and it’s this requirement to keep learning that spurs me on.

When I have free time, I’m often getting snap-happy with my digital camera, reading randomly purchased books, cycling around parks or building over-priced (but hugely enjoyable) Lego sets. After all, we’re all big kids really!

It’s my love for nature & quest for new challenges that convinced me that RunUltra was the place to be. There clearly is a small but hard-core fan-base who value ultra running more than anything in this world and that truly is inspirational.

So in a nutshell, that’s me. I can’t wait to speak with you on our social media channels but feel free to say hi on my own Twitter feed to: @AdzFlowers (It’ll prove you’ve read this far at least).

Oh, and in case you were wondering:
K - Know what you want
F - Find out if you’re getting it
C - Change what you’re doing.


Luke Jarmey
Community Manager

Luke is our Chief Listener for runners and is their relationship manager. Luke's role is to build our active RunUltra member base and reach out to the communities of runners across the internet. He invites them to connect with us and share reviews on our huge list of ultra events around the world. Luke works closely with Adam on making sure our runners know how they can participate in our online runner communities.

Here's more from Luke about his life story and passion for sports and the outdoors:

Whilst sinking my teeth into a Geography and Geology degree at the University of Manchester, I decided that upon graduating I had better rock out as fast as I could to Chamonix in the French Alps. I wanted to immersive myself in the ice-covered peaks and forested valleys. Three years later and I’m still here…

My passion could be defined as ‘mooching’ my way through the mountains via a variety of mediums; these being Skiing (of the Touring, Freeride and Mountaineering flavours), Running and Mountain Biking.

Particular highlights have been ski touring 4000m peaks such as the Gran Paradiso, the Bishorn, climbing and skiing various couloirs around the Mont Blanc Massif.

I also love to use photography as a tool to capture and encapsulate the emotion experienced through outdoor adventure. I love being able to invoke a feeling through an image; be this the sheer grandeur of a mountain face shrouded by cloud, the power of a well executed turn, or the look on someone’s face as they concentrate on their next move.


Alice Morrison
Writer and Editor

Alice has joined RunUltra as a writer and editor for the articles and reviews that are posted on the website and in the newsletter. Her background is as a journalist in magazines, on TV news and online. In 2011, she stepped off the corporate treadmill to race across Africa on a bike and she is now pursuing a career as an adventure writer.

This is what she has to tell us:

I came to running really late when I decided to run the Marathon Des Sables in 2014. I hadn’t even run a marathon when I signed up and “reluctant” would best describe my approach to my morning training. So, my first marathon was actually an ultra and I found that I relished the adventure of the long miles.

I love it best when it is just me and my trainers out in the wild somewhere. I am never going to be a great runner, or even a good one, but I can endure a lot of pain, so enjoy the longer events. I also found it to be a really welcoming community, with a fantastic sense of the absurd.

My aim at RunUltra is to work with our team of contributors to make our content absolutely brilliant!
