Riders contending for the series overall are measured on their best five results, with seeding counting for up to 50 points and race runs up to 200 points for the win.
The course itself is steep and technical as it winds itself down the famous Llangollen hillside with a spectator route cut top to bottom meaning nobody has to cross the course.
Saturday is practice all day from 09:30 to 18:00 with live timing in place for all riders.
Sunday is practice in the morning followed be seeding runs and then one race run, again with live timing throughout.
On Sunday between the intervals for seeding and race runs the Strider Downhill Race is packed with 40 stars of the future who will tackle a course that starts next to the famous Llangollen step downs.
They will then fire into the long finish arena and across the finish line and into the hot seat. The Strider riders will be in age categories and complete downhill timed runs.
