This unique ultramarathon format challenges runners to complete a 4.167-mile (6.7 km) loop every hour, on the hour.

Runners must start each loop precisely on the hour. If you fail to complete the loop within the hour or do not start the next one, you're out! The race continues until a single runner completes one final loop alone, crowning them the Last Person Standing.

Each loop is 4.167 miles, taking in the beautiful grounds in and around Turvey House.

The loops are all off road incorporating fields and woodlands.

The race will commence at 9am sharp.

All runners need to be registered by 8.15am, ready for safety briefing at 8.30am.
