For those of you taking note. YOU CAN pick a good line going up to Brown Knoll.
Yes there are better lines if you stick left a bit. Particulary just as you start the final climb to the top, you drop down a bit then climb again. Always always stay left, it saves you going in that ultra boggy bit.
Just thought I would mention that after the race.

A big thankyou to the marshall who provided the ladder at the barbed wire fence after the descent off lose hill. Nice touch
