THE HEART OF WALES ULTRA MARATHON 2026
An adventure through the ancient borderlands where Wales meets England
MAY 2nd 2026
Join us as we set-off to discover the HEART of WALES and 30 miles of true welsh beauty. An ultra marathon designed to discover everything mid Wales has to offer. Starting from the town of Llanidloes, the route takes in the Sarn, Glyndwr’s Way, Severn Way and Wye Valley Walk. Heading out towards the breath taking Clywedog Reservoir, stepping on to the infamous Glyndwr’s Way, then onwards to the HEART of WALES and the source of the River Severn before heading back to the picturesque town of Llanidloes.
The Heartlands of Wales
The Heartlands of Wales circular is a spectacular combination of 4 trails merged into 1. Meandering through the heartlands of Wales, the route takes in the Sarn, Glyndwr’s Way, Severn Way and Wye Walk in what must be one of the most spectacular areas of Wales.
Point of interest
The Clywedog reservoir is a reservoir near Llanidloes, Wales on the head-waters of the River Severn. Don’t worry, you won’t miss it.
In 2025 we had a record number of runners, a 100% finish rate and our female runners outnumbered our male runners. Challenge your perceived limits in a safe, supportive and friendly environment. Join us for the HOWUM in 2026!

Time Limits and Checkpoints
Please note we do not have time limits. Like we’ve stated previously, you’ve trained and paid to enter this race… We owe it to each participant to provide the help, support and time to get you to the finish line. Although we want our participants to challenge themselves, we don’t believe you have to run your heart out to do so. Take in the scenery, have a chat with a local, but most of all… enjoy the adventure!
In terms of Checkpoints, there are 3 along the route. They will be fully manned and stocked with snacks, fresh fruit, drinks (hot and cold), seats, power banks and music . Please include your dietary requirements when signing up, and we will accommodate accordingly.
