The flat profile of this event does indeed make pacing tricky. There is actually one hilly part, but it
I essentially ran the first 25 miles, then switched to a time based strategy of run 25 minutes walk 5 minutes. As the race progressed, I dropped the ratio down to 20/5 and later 15/5. Some people with more experience of this sort of thing than me, advocate using a 25/5 strategy straight from the starting gun, and have suggested that I would have got a better time had I done this.
As a rule of thumb, I would expect a person who takes 4 hours to run a city marathon, to finish this event in about 9 hours using a run walk strategy. Unless you are very fast, it will be dark when you cross the finish line, and you will need a head torch.
