Thwarted Rebellion


The Thwarted Rebellion is a 75 mile (120 Km) Ultra Marathon in Mid Wales starting on 15th July 2022. It follows the first 75 miles of the Glyndwr’s Way National Trail with a total ascent of just over 12,500ft (3810m). The event starts in Knighton, just on the Welsh border and finishes in Machynlleth. It is one of the most beautiful and demanding ultra running routes in the UK.

The Glyndwr’s Way National Trail is an unusual National Trail as it doesn’t follow any particular geographic features or any historic routes and offers a great ultra running change. It is named after Owain Glyndwr who led a rebellion against the English and the last Welshman to hold the title Prince of Wales. The Glyndwr’s Way is an arbitrary route merely linking a variety of towns and villages with Glyndwr connections. This the reason for its unusual V shape.

The race starts at 19:00 on Friday the 15th July 2022 and has a very generous 40 hour time limit to reach Machynlleth (11:00 on Sunday 17th july 2022). Meaning competitors must average just 1.85 miles (3km) per hour to complete the race. There are 2 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.
