The course is mainly along quiet country roads through the stunning Ashridge Forest but this year with NO canal sections.
The routes are well sign-posted with mile markers every mile, fully marshalled with water stops and much-loved jelly baby stop!
At the end there will be well-earned tea, coffee, juice and cake waiting for you as always!
