Guildford St. Martha’s Trail MapRun


St Martha’s Trail Run is one of our MapRun “virtual” courses and about 10km long (nominal length of 9.2km and a climb of about 220m).  The circular route starts from Newlands Corner on the outskirts of Guildford, heading northwest into the woodland, then along the North Downs Way aka Pilgrim’s Way to St Martha’s Hill returning via Pewsey Down.  It’s mostly bridleways so there should be plenty of space to social distance, but you might come across some cyclists as it includes part of Cycling UK’s 150 miles North Downs Way route.

On the way you reach St Martha’s Church, with the original structure dating from the 12th century, although rebuilt in the 19th century.

There are 10 controls to guide you on the way.  Navigation won’t  be too difficult as the MapRunF app will show your track and current position.  The map is at 1:15000 scale and is similar to a traditional orienteering map but with white denoting any type of woodland (rather than the usual green on an Ordnance Survey map).
Although the map shows the Start and Finish at Newlands Corner, you can start anywhere on the route (but you must finish at the same control).  This may be more convenient for you!

It’s easier to follow a printed map – the “Map” link below gives you an A4 (Landscape) pdf to print out – if you print it out ‘Actual Size’, then the scale will be correct at 1cm = 150m.  The Control Descriptions and Safety Notes are included as the 2nd page of the map. To see the times / tracks of other runners, use the “Results” / “Tracks” links below.

Safety Notes:

  • The trail has been created from Open Street Map – we can’t guarantee that a route shown on the map is a legitimate right of way – please keep to public roads, paths and open spaces.
  • When running the trail please be aware of horse riders / cyclists / walkers – maintain social distancing and give way if necessary.  Please follow the applicable government COVID-19 restrictions and the British Orienteering Covid Guidance.
  • This trail is located in Surrey which from 20/12/2020 is in a Covid Tier 4 area and from 05/01/2021 is subject to National Lockdown.  Our understanding is that a single daily session of (local) outdoor exercise is permitted for those not required to self-isolate, but you should not travel beyond your local area to do it (see British Orienteering Stay At Home Guidance).  You should check current government rules for yourself as to whether this activity is permitted – don’t forget that your name will be shown in the MapRun results!
  • When encountering horses on the bridleways, approach carefully and don’t startle them – make sure they can see you clearly.
  • The area is popular with cyclists – be alert to mountain bikes, there won’t be much warning of them.
  • Parts of the trail may be quite muddy and slippery, especially in winter – please choose appropriate footwear!
  • Particularly around Newlands Corner (Controls 1, 2, 3 etc.) you will encounter many yew trees (Taxus baccata) – all parts of this tree including berries and leaves are extremely poisonous (to humans and dogs)!
  • You will need to cross Guildford Lane, Halfpenny Lane and White Lane, none are usually busy but can used as a short cut at times – check for traffic including cyclists before you cross!  For this reason, under 16s MUST be accompanied by a responsible adult.
  • You are responsible for your own safety – this has NOT been registered as an event with British Orienteering and is not covered by their liability insurance.
  • Nearest A&E Hospital: The Royal Surrey in Guildford GU2 7XX. Directions.

Parking is at Newlands Corner Car Park,  (GU4 8SE) off the A25 Shere Road, SE of Guildford.  There are no parking charges but it can be busy.  If starting elsewhere, then there are 4 other car parks available with approximate positions on the pdf map:  Guildford Lane (2 locations, both GU5 9BQ) / Halfpenny Lane (GU4 8PZ) and the Chantries (GU4 8AW).

The Start and Finish on the pdf map is at the far western end of Newlands Corner Car Park – where there’s white hatching on the carpark and a footpath heads north west into the woodland, next to a disused Pay and Display parking machine.

But don’t forget that you can start at any control on the route, just follow the Controls in order (when you get to Control 10, go to the Start Control, then Control 1 until you get back to your starting Control).

When you pass the Finish control, then it will stop the timer, once you have started and found at least one other control.
