its my first time to Beacon's Field, and i'm planning to drive with the family (the run is almost on our route North), and have noticed from looking at a course map that the postcode you gave for the catholic high school is not the nearest car park to the race. where are folks parking? thanks!!!!!
Hazel,
My directions above are from the race (hart's lane) to the showers (college)...
If you park there you'll have about 3 miles jog through Skem to the race...
I won't advice it unless you feel really energetic ;D
Below you can find the directions from Garston to the race (hart's lane)..
