Up Hill Down Dale are excited to release the Rebellion.

The Rebellion is a 135 mile (217 Km) Ultra Marathon in Mid Wales.

The route is along the full length of Glyndŵr Way National Trail with a total ascent of just over 25,000ft (7700m). The route takes you through some of the most beautiful and remote parts of Mid Wales. Starting in Knighton looping through Machynlleth and then finishing in Welshpool - the route is one of the most picturesque and challenging in the UK.

The Glyndŵr Way National Trail is an unusual National Trail as it doesn’t follow any particular geographic features or any historic routes. It is named after Owain Glyndŵr who led a rebellion against the English and the last Welshman to hold the title Prince of Wales.

The Glyndŵr’s Way is an arbitrary route merely linking a variety of towns and villages with Glyndŵr connections. This the reason for its unusual V shape.

The race starts at 7pm on Friday and has a 72 hour time limit to reach Welshpool (7pm on Monday). Meaning competitors must average just 1.85 miles (3km) per hour to complete the race.

There are 4 checkpoints on route that all competitors must pass through within a time limit. Each checkpoint is a community hall/leisure centre that is well stocked with food, hot drinks and water for competitors to recharge and re-supply. There will also be floor space at each checkpoint for competitors to sleep if they so wish. Competitors can use drop bags, accessible at each checkpoint.
