Mardley Heath

Welcome to one of our Saturday series events which is also part of the club Youth League. Beginners are very welcome and there are courses for all standards.

TERRAIN Mardley Heath is a small but complex woodland, mainly regenerating naturally following gravel extraction in the middle of the last century. A small area of open heathland has been maintained in the northern part of the site. The area is now a Local Nature Reserve owned and managed by Welwyn Hatfield Borough Council, who have kindly given us permission for our event.

Gravel working has left this area with complex contour detail, in addition to the already hilly nature of the site. Public access for walkers, horse riders and cyclists has added a maze of small footpaths. Open areas and the mature remnant former woodland offer fast running, whilst the less mature areas provide plenty of route choice where close contact with the map will be required.

PARKING The event centre is Scout & Guide HQ, Canonsfield Road, Welwyn, AL6 0QA. OS grid ref TL242179

Free parking on the road near the event centre and around the A1(M) bridge. Space is very limited and it would be greatly appreciated if people could share transport. Many of the local lanes are not suitable for parking, so to minimise congestion please follow marshals’ instructions.

PUBLIC TRANSPORT Bus 300/301 from Hemel Hempstead, St Albans, Hatfield, WGC and Stevenage stops at the bottom of Canonsfield Road roughly every 20 minutes on Saturdays.

BEGINNERS First timers are very welcome. Look for our greeters in hi-vis jackets who will give you socially-distanced help.

If you’re not run before, we suggest most people start with yellow. Young juniors, say primary school age, and family groups are better on white. People confident with a map and compass may start on orange.

Note for improvers – if you are not sure which course to choose, best to be cautious. Mardley is a complex area.
