The closing date for online entries is 18:00 on Friday 13th February
However to be guaranteed a course map on waterproof paper for your chosen course you MUST pre-enter by midnight on Monday 9th February
We will print some extra waterproof maps for late entries. After the cut-off date, if your preferred course is full (see entry limits below), contact eventadmin@esoc.org.uk and we may be able to offer you a non-waterproof version (at the same cost).
