Safety and legal Notices

You must be fit to take part, and if necessary, should seek advice from your GP before entering the event.

Entrants must take care when crossing roads, although marshalling assistance may be given.

Whilst every reasonable care is taken, entrants cannot hold the organisers, sponsors or landowners responsible for their safety

The course is unsuitable for wheelchair users, and no accompanying dogs or following cycles are allowed

All entrants must show consideration for other users of public footpaths and rights of way.  The route is open to the general public and crosses main roads a number of times.  The traffic on these roads will not be stopped.

Entry fees are non-refundable, including the cancellation of the event due to circumstances outside the organisers control.  Entrants are permitted to transfer their place via the results base entry system up to 12 noon on 22nd March 2024.  Entrants are also permitted to defer their entry for one year but only if they have contacted the race organisers by email by 12 noon on 1st March 2024.  Please see the entry page of this site for more details.

In the event of the race being cancelled due to the impact of COVID, entrants will be contacted and entry deferred until the following event.

The organisers reserve the right to withdraw entrants from the event and anyone that opts to continue does so entirely at their own risk.

The run will take place through rugged, uneven and potentially muddy terrain.  Appropriate footwear must be worn.  It may also be cold or wet and thus entrants must take reasonable precautions.

There is no official cut off, and ‘not fast’ runners are very welcome.  However we expect runners to be able to complete the course in under 4 hours 15 mins (those going slower than this will find that marshals have been removed).  We expect all participants to run the vast
majority of the course.  Please don’t enter if you expect to walk a substantial part of the course.

The route is around an area of outstanding natural beauty so please ensure that no rubbish is left or discarded at any point on the route.

Details of the Ashridge Boundary Trail route can be found by clicking here.  The only deviation from the official boundary route is that entrants will go to the top of Ivinghoe Beacon.  The National Trust has advised that due to ensuring no damage is done to the top part of the beacon, a small route variation may take place on the day.  Entrants will be advised of this in advance.

The route is well signed and marshalled on race day.  We haven’t lost any runners yet !

The start and finish of the race will be at the Aldbury recreation ground, Stocks Road, Aldbury.  There are toilets and ample free parking available at the start.  Please park in the field as directed by the marshals.

The use of ipods and mp3 players is permitted but please ensure that you are able to hear other runners and marshals if using them.

Competitors will not be allowed to start the race after 10am, so please ensure you arrive before this time.  If you arrive late and decide to run in any event, you will not be issued a number.


There are toilets at the start/finish.  No showers are available
