Altra Kielder Marathon, Britain’s Most Beautiful

+ 10k, Duathlon, Half, Junior

2nd - 3rd October 2027

03/10/2026

That’s a wrap on day one of the 2026 Altra Kielder Marathon Weekend — and what a way to kick things off🌲🏃‍♀️🚴‍♂️

A huge thank you to everyone who joined us — whether you were racing, supporting from the sidelines, volunteering or simply soaking up the atmosphere. You helped make Saturday one to remember 🙌

We started the morning with a Rise & Stretch session with Lucy Aldridge ⚡️ of teamcycles.com, followed by an Altra Women’s Shakeout Run powered by the BOLDLI | women’s running safety + community She Runs Free team, and a foot health workshop led by James Wauchope.

Then, it was time to hit the trails. Kielder was buzzing as runners and riders took on the 10K and Gravel Duathlon, with brilliant performances, muddy miles, big smiles and plenty of memorable moments along the way🌲

We rounded off the first day with An Evening With The Founders — an inspiring conversation between Brian Beckstead, Altra Co-Founder, and Steve Cram CBE, Kielder Marathon Founder, hosted by North East Mayor Kim McGuinness. The evening brought together stories, memories and plenty of insight, all topped off with pizza 🍕

A massive thank you to all of our incredible partners for helping us bring the weekend to life, with a special shoutout to our title partner, Altra, for their amazing support👏

One day down…and we’re only just getting started. Tomorrow, it’s time for the Half Marathon, Marathon and Junior races🌲🏅

Bring on day two 👀

Today’s the day! We’re back for the 2026 Altra Kielder Marathon Weekend and it’s a special one, because this year, we are celebrating 100 years of Kielder Forest.

In April 1926, a small area of experimental planting of trees took place in a remote area of northern England. It would lead to the country’s biggest forest, which a century later spans 250 sq miles (447 sq km) across Northumberland and Cumbria, with 158 million trees mostly planted by hand.

Kielder Water is the largest man-made lake in Northern Europe by capacity, with Kielder Forest being England’s largest working forest.

The area is known for its breath taking beauty, wilderness and is a designated Dark Skies site. The shore line, including Bakethin is 27 miles and has a surface area of 2,740 acres. At its deepest point, the reservoir is around 52 metre and is capable of holding 44,000 million gallons of water.

Kielder Water is a hidden gem with only small towns and villages in close proximity. It’s truly the star of our show and it’s why the Altra Kielder Marathon is called Britain’s Most Beautiful.

We’re delighted to welcome you down to Kielder this weekend to celebrate. See you all on the start line 🏁
