If you are thinking of newly joining CHIG, if you join in November or December 2019, you get these months free when you take a membership for 2020. Memberships are available online via the British Orienteering website.
Senior memberships (which include British Orienteering membership) are £25 and only £6 for junior memberships.
For existing club members who pay by direct debit, these will be taken in December. Club members who do not currently use direct debit can set this up on the BOF website or choose to pay for 2020 online using debit card.
