Starting in the Town Square at 10am, hundreds of runners are expected to set off on the run, which first takes them downhill for half a mile, before turning left at Riverside and continuing on out of town to reach the road leading out to Newmills. From there, they will climb to Tregadillett, then there will be a steady downhill race via Treburseye, Upper Chapel, Moorland Road, St John's Road and Western Road, before reaching the finish line in the grounds of Launceston Castle.

The race is part of the Cornish Grand Prix and is organised by Launceston Road Runners. It attracts runners from across Devon and Cornwall every year, and has become one of the most anticipated local sporting events in the calendar. What's more, there is still time to sign up if you've been thinking about taking on this challenge.

• Tregadillett, 10.15am to 11am
