Start Times


We will be aiming to get the 50k and Marathon registrations done first and away as soon as possible.


We cannot get into the school before 7:30 So please bear with us, we will work as quickly as possible to open registration. Registration will open as soon as we have the gazebo set up. Once we have the first small group of people registered we will give a short safety briefing and send you out in small batches.


Toilets may not be available initially.

Briefings will then be every 10 minutes. Runners can leave at any point once they've been briefed. Briefings will include important information updates. Ensure you have registered your start time with the start marshall, the event is manually timed.
