The length of the course is very challenging and for competitors own safety and fairness the following rules must be adhered to. Failure to comply with these rules may result in disqualification from this and future events.

The Event

The Windsor Ultra is organised by Ultra Running Limited and is open to individuals who must achieve a minimum 4 mph pace. Below 4 mph you will not be allowed to continue and stopped at the first available check-point. All entrants must be 20 years of age or over at the start of the race. Each competitor must ensure that they carry with them all of their individual requirements needed to complete the race.
Every entrant must confirm that they have read these rules and other event information and therefore understand the nature of the event and that participation is at their own risk.

Race Entries

Competitors must register at the start location at least one hour before the start of the race and present their kit for examination on request. Race start is 8.00 am.

Each participant will be given a race number which must be clearly attached by safety pins to the front chest. If this is not clearly visible you may be delayed at checkpoints.

Competitors must be self-sufficient, and carry the following mandatory items:

a. Backpack or equivalent
b. OS Map for their route
c. Compass or GPS device
d. Whistle
e. Mobile phone
f. First Aid Kit
g. Reusable cup for CP Stations

Checkpoints and Water Stations

The Windsor Ultra benefits from three check point stations which are at pre-determined points along the route. The race organisers will provide water and some nutritional nibbles at these check points. Please remember to bring your reusable cup as all of our events are now cup-free.

Competitors must go through all check points and it is their sole responsibility to ensure that the check point attendant has recorded their race number; failure to do so at any check point will mean the competitor has failed to complete the race and will be disqualified.

Any competitor found to not follow the pre-determined race route will be disqualified.

Competitor Retirement

If any competitor has to retire for whatever reason they must contact the race organisers immediately, either by advising a checkpoint attendant or telephoning the emergency number given at the start of the race. The emergency number will also be written on each competitors Bib number.

Time Restraints

The Windsor Ultra is incredibly demanding and few athletes will have the fitness or resolve to complete the course. As such Ultra Running will pre-set cut-off times based on a minimum of 4 mph along the route. In addition, if Ultra Running or any of its representatives deem for any reason that a competitor should not continue, Ultra Running Limited’s decision will be final.


Camping facilities are available, at an additional cost of £35.00 per person, which includes pitch cost and tent hire. It is requested that all of these facilities and the Windsor Ultra route itself, are respected and kept litter free by all competitors, family, friends or anybody else with an association with the race.

The organisers are more than happy to source alternative accommodation such as B&B or hotel, subject to availability and cost at any of the camp locations for any family member or supporter who wishes to attend the event.
