Challenge is the key word with this one. You must rely on your own navigation skills to get through. Great drinks stations with water, squash, bread pudding and a good amount of spectators in the villages. It's mostly trails. No course markings, no course marshals and no police support. This is all as advertised. It's a challenge. You make your way around the course by following written instructions. It really was a lot of fun and I plan to run it again even though I usually don't do a marathon twice.
