Course Details

Half marathon - Starts at 9am
The half marathon is fully signposted. You'll explore several ancient woodlands and forests, climb to the highest point in Cardiff (Rhymney Ridgeway), and enjoy panoramic views across South Wales and the Bristol Channel. The elevation is 2,400ft but with a generous cut-off of 6.5 hours, this event is suitable for runners or fast walkers (2.5mph).

Marathon - Starts at 8am
With over 4,500ft of elevation you will encounter plenty of climbs including to the top of Machen mountain and the Rhymney Valley Ridgeway - both will reward your efforts with sensational panoramic views.

Of course, there will be plenty of thrilling descents too!

The full marathon requires self-navigation for the first half before picking up the, fully signposted, half marathon at the midway point. This makes it ideal for runners whose map reading skills falter as they tire. Trackers will also be provided.

Cut-offs - Half marathon
For the half marathon, cuts off are generous and allow for approximately 2.5 mph progess - fast walking. Remember there are some hills so this is quite a challenge if you're considering walking the entire route.

Race Start: 9:00
CP1 Cut Off: 10:30 (4 miles) (no supplies here)
CP2 Cut Off: 11:45 (6.8 miles)
CP3 Cut Off: 13:15 (10.6 miles)
Race Finish: 14:30 (14ish miles)

For the Full Marathon, since we see this as a race for the more experienced runner, there will be an overall time limit of 8 hours for the full marathon route. This equates to about 3.25 miles per hour.

Cut-offs - Marathon​
CP1 Cut Off: 11:20 (11 miles)
CP2 Cut Off: 12:30 (15 miles) (no supplies here)
CP3 Cut Off: 13:30:45 (18 miles)
