Yes. There are sections of the course where you will be running along single lane carriage ways or crossing busier B roads. The trail does appear at busy junctions, at some points abruptly and therefore you must be alert at all times. Runners pass along the course entirely at their own risk. Much of the course is on private land and as a result there are gates and stiles to negotiate. All gates must be closed properly after you make your way through.
A full aid station list is available here.
There will be 16 aid stations including the finish.

If you need to answer a call of nature whilst on the route you must make sure you are as far off of the marked trails as you can go.
No. The hall we use for HQ is small and constantly extremely busy with the coming and going of runners and volunteers. We advise all runners to book accommodation in Goring or Streatley for the night before and after the race. Do not attempt to drive home directly from the finish without sleep.
