Eston Moor and Lazenby Bank are on the south side of Middlesbrough, east of the A19 and south of the A174.

Parking, registration and the finish are at the NHS offices off Flatts Lane, Normanby on the south side of Middlesbrough.  For most people the best approach is from the A171 between Nunthrope and Guisborough, from which the event will be signed.  (Please note there is no access directly on to Flatts Lane from the A174 eastbound).  The grid reference of the entrance to the car park is NZ 552170 and the postcode is TS6 0SZ.

There are three distinct parts to the competition area.

Eston Moor is a relatively flat area of open moorland with many paths, a few wooded areas and areas of thicker vegetation.  Many parts of the moor offer fast running.

At the northern edge of Eston Moor there is a fairly steep slope leading down to the farmland below.  On the slope there are small patches of trees and a number of rock features.  The bracken gets high during the latter part of the summer, but will be much less of a hiderance to progress at this time of year.  The start is likely to be along this slope.

Lazenby Bank extends to the east of the Eston Moor slope.  The area is well contoured and wooded and adds a different navigational and physical challenge to the moor.  The proximity to the Start allows all courses over 4 km to reach this area.

Note:  As the event is taking place in April and the competition area includes exposed moorland, it's quite possible that cagoules may be made compulsory.  Please come prepared.


White, Yellow, Orange, Red, Light Green, Very Short Green, Short Green, Green, Blue and Brown.

Note: The Red course (sometimes called 'Long Orange') is suitable for runners with limited navigational experience.  It aims to give you a good run out with enough navigational challenge to make things interesting.

Map: Scale 1:10,000 with 5m contours.   The courses will be overprinted on the maps, which will be printed on waterproof paper.
Punching system:

SPORTident electronic punching will be used.

The controls will be enabled for touch-free SIAC punching, but please note that all competitors – including SIAC users – will need to punch manually at the Start and Finish.

SI-cards will be available for hire on the day at a cost of £1 each.  Please look after your hired SI card as there will be a £40 charge for any lost SI-card.
