Built in summer 2009, Root Canal (formerly known as 423) has been used as a race track for various regional champs, and features every year on the Aston Hill race calendar.

Straight off from the start you’re into one of the biggest features of the track, a table top landing down onto the fireroad. Getting progressively steeper as it goes down, the track continues into a series of jumps, loose turns and finally ends up at the infamous J-turns before dropping into the finish.

Trail surface types
