The 10 km course has about 393 m of ascent and reaches around 508 m. All routes are fully marked. The 21 km has a 5 hour time limit; the 10 km has a 3 hour time limit.

Entry fees are listed as 10k £32 and 21k £37 plus a 5% online fee, with a minimum entry age of 17. Entries close in early November and no late entries will be available.
Hydration stations: two on the 21 km and one on the 10 km, located at Spooky Wood and Tower Rig for the 21 km. Stations may be moved or removed in icy conditions; no cups will be provided so runners should carry their own drinking system. A kit list is mandatory for 21 km participants. Sections of the routes are used with Forestry Commission permission and may be busy with mountain bikes outside the event. Visit the organization's website for the most recent information.
