Intresting to read at the bottom of the results, that the cut off time may be reduced at checkpoint 4 by 15 minutes and the entry on the day increased to £15.00.
The RO thinks that this will mean last runners finishing around the 4hr 30mins mark and encourage pre entry.
Sounds like a good plan to help out the marshalls, but how pee'd off would you be if you missed the cut off having paid £15 quid .....
