Straight the Taff Trail south to Abercanaid, Troedyrhiw and Aberfan and back

10 mile runners do 1 loop, 20 mile runners do 2.
Q. Can I wear headphones?
The short answer is 'No'. As the route is mainly off road and there are a few crossings, being able to hear the race marshalls is important. Also, the course is on the shared route of the Taff Trail with walkers and bikers also out and about.
Q. Is there a cut off time?
For the 20 mile race, 'Yes'.
The Race Time Limit is 4 hours and 30 minutes. To ensure this is adhered to we will operate a course closure at the 10 Mile mark at 2 hours and 15 minutes.
Please do not enter the 20 Miler if you cannot achieve the cut off and the final time limits.
