- Parking - Is in Dorking Railway Station car park, a 10 minute walk away. This is a pay and display (FREE on Sundays we believe…) and a short walk to Denbies.

If the weather and conditions allow then the parking will be at the race base in Denbies - this won’t be confirmed until near to the race, but plan for having a short walk from the nearby Station car park.

- Venue - Denbies Wine Estate, Dorking, RH5 6AA

- Bag Drop - There is ample undercover storage for you to bring warm clothes for before/after the race and leave in our marquee venue space. Any bags / belongings will be left AT YOUR OWN RISK, though there should realistically be members of our team in and around the venue area at all times. (a fairly waterproof bag will be best, as the bag drop area will be on our tarpaulin sheets on the ground in the marquee…)

- Registration is from 8.30am and will be signed and set up in the event HQ marquee within Denbies grounds, adjacent to the start & finish. Here you will receive your race number, any event T-Shirts etc etc. Toilets will be situated here.

- Race start is 10am

Kit List for this race has been planned to ensure you have AT LEAST the bare minimum with you to be safe in the event of bad weather or accident and takes into account the time of year, regular support on the course and ease of access to the the route should there be an emergency.  This basic kit is mandatory and is to be carried by each participant at all times during the race.  

  • Waterproof Jacket (Windproof not sufficient, must be hooded jacket with taped seams)

  • Hat (Buff or cap acceptable as your head cover)

  • Foil space blanket (even better, one of these!)

  • First Aid Provision - Sterile dressing and bandage as a minimum

  • Charged mobile phone (Waterproofed in plastic freezer bag or equivalent)

  • Hydration system with minimum 500ml capacity

  • Folding Cup for drinks in Checkpoints - there will NOT be plastic/paper cups for participants in this race. You may use your bottles in checkpoints instead of bringing a cup - that’s fine. The point is we will NOT have cups for you at checkpoints!)

  • Basic nutrition (to be supplemented via Checkpoints)

  • Consider an extra layer to have with you in case of accidents or a turn in the weather

  • Headtorch - this is not mandatory for everyone to carry. BUT if you are expecting to be out for around 7 hours or more then you will need one!


- Running poles and Headphones are allowed but please be aware and considerate to other participants and members of the public at all times.  Take headphones out when crossing / following any roads during the route.

Time Limit is 10 hours from your race start.   This event is purposefully accessible to people wishing to try an Ultra distance running race or for those wishing to walk the whole way.

We recommend having a gps device as backup whilst you are running - many running watches allow you to upload the route onto them, or viewranger is a great free app to enable your smartphone to be used as a gps.

Route Markings are small permanent discs that are generally fixed to posts with an obvious 'North Downs Way’ on them whilst you are on this Trail.  The race route follows just over 12 miles of the North Downs Way from Denbies to the edge of Guildford, then returns the same way before leaving the NDW for a roughly 6 mile loop through Westhumble and Norbury Park. We will also use plentiful race specific signage throughout the route.  These will be small blue arrow signs with the FR from our logo on them, stapled to posts to guide you.
