The HARD FORT duathlon is the main event of the day and is not for the faint of heart. The amount of climbing will test the toughest of athletes. Your reward though, is breathtaking, unspoilt scenery to rival anything you have experienced in a race before. See below for an overview of the course.

Run 1 – 20km
A very challenging 20km route that starts and ends on road. The majority of the route is on footpaths, trails and forest paths and after circumnavigating Colstey Wood, continues on to Sunny Hill and the ancient Bury Ditches Hill Fort.  After the Fort summit, there will be a short section that skirts the hill before retracing the route back through Gilden Down and back to transition.

Bike Course – 91km
The bike course heads north from Clun towards Bishops Castle.  The first key climb ascends from the A489 and to the summit of the Kerry Ridgeway. A long fast descent back to Clun is then followed by the notoriously leg-sapping double-climb from Clun to New Invention and then to Knighton. The course then head back to Purslow via Twitchen and rolls gently back to Clun. Beware – this is a tougher course than the profile suggests.

Run 2 – 11km
Two laps of a 5.5km route, the second run leg heads away from Clun with an initial long drag up hill before turning around for a fast descent. Followed by circling the town via the river, the church and finally the picturesque castle, before heading through the streets and back to race HQ, before completing another loop and finally in to finish the race.
